Vincent (Princeton University)","","2024","Peer-to-peer (P2P) energy trading and energy communities have garnered much attention over in recent years due to increasing investments in local energy generation and storage assets. Much research has been performed on the mechanisms and methodologies behind their implementation and realisation. However, the efficiency to be gained from P2P trading, and the structure of local energy markets raise many important challenges. To analyse the efficiency of P2P energy markets, in this work, we consider two different popular approaches to peer-to-peer trading: centralised (through a central market maker/clearing entity) vs. fully decentralised (P2P), and explore the comparative economic benefits of these models. We focus on the metric of Gains from Trade (GT), given optimal P2P trading schedule computed by a schedule optimiser. In both local market models, benefits from trading are realised mainly due to the diversity in consumption behaviour and renewable energy generation between prosumers in an energy community. Both market models will lead to the most promising P2P contracts (the ones with the highest Gains from Trade) to be established first. Yet, we find diversity decreases quickly as more peer-to-peer energy contracts are established and more prosumers join the market, leading to significantly diminishing returns. In this work, we aim to quantify this effect using real-world data from two large-scale smart energy trials in the UK, i.e. the Low Carbon London project and the Thames Valley Vision project. Our experimental study shows that, for both market models, only a small number of P2P contracts i.e. less than 10% of the possible P2P contracts are required to achieve the majority of the maximal potential Gains from Trade. Similarly, only a fraction of prosumers are required to participate in energy trading to realise significant GT; namely we found that 60% of the maximal GT can be realised with only 30% of prosumers’ participation, with the percentage of maximal GT reaching 80% when participation increases to 50% of prosumers. Finally, we study the effect that diversity in consumption profiles has on overall trading potential and dynamics in an energy community. We show that in a community with a DF(load diversity factor) = 1, 80% of potential maximal GT can be achieved by 10% of prosumers engaging in P2P trading, while in a community with DF = 1.5, it is beneficial for 40% of the prosumers to trade.","Peer-to-peer trading; Energy community; Negotiation","en","journal article","","","","","","","","","","","Intelligent Electrical Power Grids","","",""

(mentor); Kamp, L.M. (mentor); Delft University of Technology (degree granting institution)","2023","The global shift towards sustainable and renewable energy sources is an undeniable necessity. Energy communities, grounded in principles of community participation and environmental sustainability, are emerging as key players in driving this transformation. Flanders, a region in Belgium, has witnessed the rise of energy communities as they take on the challenges and uncertainties inherent to their mission. This thesis embarks on a journey to uncover the dynamics, challenges, and opportunities that these energy communities in Flanders face in their quest to facilitate the energy transition.
While energy communities have garnered attention as a social innovation, there remains a need to explore the specific context of Flanders, its niche development, and up-scaling patterns. To address this gap, our research focuses on understanding the unique characteristics and challenges of energy communities in Flanders and their role in shaping the regional energy landscape. This study seeks to answer the following main research question:
""What are the characteristics, challenges, and scaling patterns of energy communities in Flanders, Belgium, and how do these communities contribute to the energy transition?""
To address the research question, a qualitative data analysis with a case study approach was adopted. Qualitative data collection methods, such as stakeholder interviews, were utilized to gain insights from the local actors involved in the energy community niche. Additionally, the Strategic Niche Management (SNM) framework was applied to assess the development and scaling of these energy communities. The analysis considered various factors, including expectations, network formation, and key learning processes within the niche. Also, the concept of Scaling the Community Energy niche was analysed based on the qualitative data collected from the semi-structured interviews and the different typology patterns of scaling this niche innovation in the Flanders region have been displayed. Moreover, the concept of shielding and nurturing the community energy niche and their future perspective in the Flanders area is discussed on.
The study uncovered a series of insights regarding energy communities in Flanders:
1. Common Challenges for Energy Communities: Energy communities in Flanders face complex regulatory environments, competition for land, and the need to enhance public awareness and business case viability. They also grapple with legislative variations, participant knowledge gaps, administrative burdens, and the need for clarity in objectives and definitions. Adapting to evolving legislation and managing transaction costs are additional challenges.
2. Challenges Specific to DSO and VEKA: Distribution system operators (DSOs) like Fluvius must reduce grid fees fairly to avoid burdening non-participants. Flemish Energy and Climate Agency (VEKA) should ensure a comprehensive understanding of complex legislation and manage administrative complexity.
3. Niche Characteristics and Processes: The research identified three critical attributes of the community energy niche in Flanders, including dynamics of expectations, network formation, and essential learning processes. These aspects were elaborated upon, providing a comprehensive understanding of the niche dynamics in the region.
The study significantly contributes to several academic debates:
1. Strategic Niche Management (SNM): The application of the SNM framework to analyze Flanders' energy communities enriches the understanding of how these communities conform to or challenge niche management processes. It confirms the adaptability of SNM in assessing their development.
2. Empowerment of Community Energy Niches: By exploring empowerment strategies used by Flanders' energy communities, the study aligns with debates on empowerment and adaptation in community energy niches.
3. Up-Scaling Patterns in Flanders: The research identified different up-scaling patterns, confirming the relevance of various strategies within the region.
4. Stakeholder Involvement: The study complements other research by providing insights into how stakeholders operate and coordinate within Flanders' energy communities.
5. Investments in Renewable Energy Initiatives: In addition to investigating determinants of investments, the study also explores economic factors like job creation, local economic stimulus, and property values.
6. Community-Based Governance and Sustainable Energy Usage: The research expands the focus on up-scaling patterns and empowerment strategies driving sustainable energy behaviour within Flanders energy communities.
Additionally, The study offers several recommendations for policymakers to support energy communities in Flanders:
- Standardize and harmonize energy community regulations across different Belgian regions to reduce complexity and uncertainty.
- Introduce participative criteria in tenders for renewable energy projects to enable energy communities to compete fairly.
- Support targeted public awareness campaigns to bridge the gap between energy communities and the broader public.
\item Explore financial incentives tailored to the Belgian context to establish a compelling business case for energy community participation.
\item Invest in educational and training programs to bridge the knowledge gap among participants.
\item Streamline registration processes and regulatory compliance to reduce the administrative burden.
\item Provide clear definitions and objectives for energy communities within the Belgian context.
\item Stay responsive to changing regulations to enable energy communities to thrive.
\item Encourage collaboration, knowledge sharing, and advocacy efforts within the Flanders energy community niche.
\end{itemize}
In conclusion, this research contributes to a better understanding of energy communities in Flanders, offering insights for policymakers and energy communities. It emphasizes the importance of empowering these communities to accelerate the energy transition and achieve lasting benefits for society and the environment in the region.
The chosen research approach is a comparative case study, focusing on smart grid integration in the Netherlands. The Institutional Analysis and Development framework aids in analyzing complex socio-technical systems, particularly energy transitions and smart grids. Three cases were examined: Schoonschip Amsterdam, GridFlex Heeten, and Groene Mient The Hague. Data collection involved literature review and 14 semi-structured interviews with experts and stakeholders. Interview data was deductively coded using the IAD framework, facilitating comparative case analysis and cross-case analysis using the ASI diagram (Actors, System & Institutions).
The transition of the Dutch electricity system into a competitive liberalized market has increased the importance of smart grids for sustainability. Decentralized energy production, facilitated by smart grids, requires technological advancements and institutional changes at various levels. Successful smart grid implementation in the Netherlands involves obtaining exemptions, feasibility studies, and engaging legal entities like homeowners' associations and energy cooperatives. Cases emphasized the significance of pre-exemption feasibility studies, technological requirements, stakeholders like Distribution System Operators, and energy management systems.
The findings highlight the uniqueness of each case and the role of institutional rules. In Schoonschip, boundary, position, choice, and payoff rules were pivotal. GridFlex highlighted position, choice, information, and scope rules. Groene Mient showcased boundary, position, choice, payoff, and scope rules. These case studies underscore complexities in decision-making and governance within smart grid initiatives. Successful implementation requires considering technology, institutions, and stakeholders as indicated by the ASI diagram. The IAD framework analysis reveals the impact of biophysical conditions, community attributes, and rules-in-use on smart grid outcomes.
Recommendations include further research on evolving rules, understanding actor positions, interdisciplinary research, integrated decision-making frameworks, empirical case studies, and policy recommendations such as financial support, clear policy roles, local smart energy systems, positive framing, standardized data exchange, and umbrella organizations for cohesive local smart grid projects.
In conclusion, the study underscores the intricate nature of smart grid implementation, emphasizing the need for comprehensive consideration of technology, institutions, and stakeholders. The IAD framework sheds light on the complex dynamics, guiding effective decision-making and policy formulation for successful local smart grid development.
Previous research has highlighted how an off-grid configuration would result in inconveniently high costs for the community's users, if compared to the average cost of energy in The Netherlands. The aim of this thesis is to study the system in a grid-connected configuration, and in particular to find the optimal sizes of the components in order to achieve the best trade off between three conflicting objectives : minimizing total costs, maximizing self- sufficiency and maximizing reliability. After modeling the system's components and their mutual interactions, the optimization was carried out on MATLAB using a variant of the NSGA-II algorithm, which provides a Pareto Set of equally optimal solutions for the problem. The solutions were then ranked with a Technique for Order Preference based on Similarity to the Ideal Solution (TOPSIS), to assist the decision-making process.
The simulations have determined that an installed capacity of 85.41 kWp (composed of 234 panels of 365 Wp each) results in the most effective choice for the solar energy generation, irrespective of the external conditions imposed. The optimal storage capacity, however, results significantly more influenced by factors such as grid imports limitations and price uncertainties. Under the conditions of limited imports from the grid, an optimal capacity of 75 kWh in the form of batteries was found. In general, the study confirms that the adoption of an hydrogen storage system is far from being convenient on a small scale residential level, regardless of the pricing conditions. The research has also posed an accent on the incremented costs incurred to reach full reliability of the system with low values of dependence from the grid, due to the high costs of the necessary storage equipment. Additionally, despite the best solutions found represent the optimal compromises balancing the conflicting objectives, reasonable solutions in terms of costs faced by the Community's users are usually not among the first choices of the ranking algorithm, mainly because they necessitate of at least 50% of the load to be supplied through grid imports.","Energy Community; Multi Objective Optimisation; PV system; Hydrogen storage","en","master thesis","","","","","","","","2025-09-06","","","","Electrical Engineering | Sustainable Energy Technology","24/7 Energy Lab",""

The current energy system causes climate change, pollution, and pressure on space (Our World in Data, 2021) (Withagen, 1994) (KNMI, 2020)(NOS, 2017). The energy transition begins to take shape, companies are investing in large-scale wind farms at sea, and people are installing solar panels on their roofs.
However, nothing changed in lifestyle and energy consumption. By approaching the energy transition from with the current mindset, it tackles the problems surrounding climate change and pollution, but the pressure on space will increase (Sijmons et al., 2014).
Throughout history, the relationship between space and energy has been great; the energy landscape signi-ficantly influenced our living environment (PBL, 2003)(Toekomstatelier NL2100, 2022). Over the years, it has become increasingly distant from our immediate living environment. Out of sight, out of mind (PBL, 2003). As a result, the consequences of unrestrained energy consumption are unclear, and people are not inclined to change. This research focuses on how this problem came about and the possibilities for the future. The design brings the energy landscape back into the living environment in the middle of the city.
The research focuses on Oud-Crooswijk, a neighbourhood in the city of Rotterdam, the Netherlands. Here, the design investigates the potential of inner-city energy production and its spatial consequences. The energy transition is the catalyst for investment in spatial quality in the district. If the development is already there, much more can be made possible.
In addition, the research shows how our lifestyle needs to change to achieve the intended quality. How people should adjust their behaviour and become more frugal and at the same time work together. As a result, the design creates a more conscious and social living environment. The research shows that by changing our behaviour and decentralise sustainable energy generation we can improve spatial quality, microclimate, and community. Now it is just a matter of daring to switch off.","Enery transition; Energy Community; Environmental psychology; Decentralised energy system; Energy potential; Urban energy landscape","en","master thesis","","","","","","","","","","","","Architecture, Urbanism and Building Sciences","","51.9324818, 4.4946682"

(TU Delft Energie and Industrie); Okur, Ö. (TU Delft System Engineering)","","2023","Energy communities play an important role in the energy transition to future clean and sustainable energy. The economic feasibility of an energy community is largely affected by its investment options: either a third party or households themselves can invest in distributed energy resources. Another common problem for energy communities is cost allocation among local community members to ensure cost recovery. For these reasons, in this paper, an economic feasibility analysis for energy communities with two investment options is conducted: third party investment and self-investment, while also taking into account various cost allocation methods. An optimization model is developed to solve the optimal operation of the energy community with both investment options. The results indicate that it is economically feasible for a third party to invest in an energy community with the right energy prices and payback time. In this case, the third party makes the highest profits when the payback time is 15 years, which is around 50% percent of its total investment cost. In addition, it is possible for the third party to have multiple cost allocation methods within the same energy community. On the other hand, local community members benefit the most from a joint investment, despite the high initial investment costs. The energy costs of each household are largely affected by the payback time and cost allocation methods. These variations are the largest when payback time is 25 years, which is also the system lifetime. Overall, this study provides insights both for third parties and households to make decisions on investment options and cost allocation.","Cost allocation; Distributed energy resources; Energy community; Investment; Optimization","en","journal article","","","","","","","","","","","Energie and Industrie","","",""

However, roadmap for PCMs’ application in carbon-neutral transition is ambiguous in the current academia, and a state-of-the-art overview on latent thermal storage is necessary. In this study, a comprehensive review was conducted on cutting-edge technologies for carbon-neutral transition with latent thermal storages. Both carbon-positive and carbon-negative strategies in the operational stage are reviewed. Carbon-positive solution mainly focuses on energy-efficient buildings, through a series of passive, active, and smart control strategies with artificial intelligence. Passive strategies, to enhance thermal inertia and thermal storage of building envelopes, mainly include free cooling, solar chimney, solar façade, and Trombe walls. Active strategies mainly include mechanical ventilations, active water pipe-embedded radiative cooling, and geothermal system integration. The ultimate target is to minimise building energy demands, with improved utilisation efficiency on natural heating (e.g., concentrated solar thermal energy, geothermal heating, and solar-driven ventilative heating) and cooling resources (e.g., ventilative cooling, geothermal cooling, and sky radiative cooling). As one of the most critical solutions to offset the released carbon emission, carbon-negative strategies with PCMs mainly include cleaner power production and waste heat recovery. Main functions of PCMs include energy efficiency enhancement on cleaner power production, steady steam production, steady heat flux via the latent storage capacity, and pre-heat purpose on waste heat recovery. A thermal energy interaction network with transportation is formulated with PCMs’ recovering heat from internal combustion engines and spatiotemporal energy sharing, to provide frontier research guidelines. Future studies are recommended to spotlight standard testing procedure and database, benchmarks for suitable PCMs selection, seasonal cascaded energy storage, nanofluid-based heat transfer enhancement in PCMs, anti-corrosion, compatibility, thermochemical stability, and economic feasibility of PCMs. This study provides a clear roadmap on developing PCMs for transition towards a carbon-neutral district energy community, together with applications, prospects, and challenges, paving the path for combined efforts from chemical materials synthesis and applications.","Carbon-neutral district energy community; Cleaner power production; Energy efficiency enhancement; Latent thermal storage; Low, medium and high-temperature PCMs","en","review","","","","","","Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.","","2023-07-01","","","Design & Construction Management","","",""

The potential of these initiatives, as identified from this clean energy production, to play a key role in the energy transition is assumed to be vital as recognized by the European Commission’s Clean Energy for All package and the provision of a legislative framework for their operation in European countries. In the light of this, European policy makers assume that promoting the engagement of more citizens in such initiatives will lead to a rise in energy justice and a fairer energy transition. However, several researches show that this assumption maybe flawed as the relation between the two is not explicitly verified. Through the acknowledgement of minority groups, this research aims to investigate whether an increased citizen engagement in energy communities could lead to a rise in energy justice. For this, the research is broken down into three key steps involving: 1) investigating what factors could affect the willingness of citizens to engage in energy communities by conducting a literature review and then evaluating potential influence of the identified factors for the city of The Hague as case study area, 2) investigating the distribution of the identified factors around areas with energy communities to find out whether there are any social groups favoured by the distribution of these factors around neighbourhoods with 24 energy communities. This is done by conducting spatial data analysis to investigate whether the engagements of any particular social groups or classes of people might be favoured by the spatial locations of energy communities in specific areas of The Hague 3) finally by conducting one on one interviews with 8 board members of energy communities in The Hague, the research seeks to investigate the relation between the identified factors potentially affecting citizens' desires to engage and the three tenets of energy justice. The results show that in the city of The Hague, although a majority of neighbourhoods in which energy communities are located are characterized by a high number of minority groups, a high majority of the energy communities interviewed (7 out of 8) acknowledge that minority groups are generally less involved. However for the classes of people engaging in such initiatives, a majority seeks to raise their powers and that of other community members in the decision making process. Hence, this allows to conclude that for the case study area, energy communities might only lead to a limited rise in Energy justice due to the partial or non-acknowledgement of minority groups.","Energy Community; Energy Justice; Data analysis; Citizen Engagement; socioeconomic factors; Recognition Justice","en","master thesis","","","","","","","","","","","","Engineering and Policy Analysis","",""

Existing studies on community energy projects are primarily focused on residential members, and have little to no inclusion of nonresidential community members. However, recent studies regarding demand response in the energy community highlight the benefits of having a mixed configuration of residential and non-residential members. Introducing non-residential community members such as SMEs, offices, and schools with a complementary demand profile can help the community in attaining self-sufficiency through demand response.

The Shapley value, a solution concept in cooperative game theory initially proposed by Nobel prize-winning economist Lloyd Shapley, has attracted increasing interest for redistribution in energy settings. However, due to its high time complexity, it is intractable beyond communities of a few dozen prosumers. This study proposes a new deterministic method for approximating the Shapley value in realistic community energy settings and compares its performance with existing methods. To provide a benchmark for the comparisons of these methods, we also design a novel method to compute the exact Shapley value for communities of up to several hundred agents by clustering consumers into a smaller number of demand profiles. Experimental analyses with large-scale case studies of a community of up to 200 household consumers in the UK show that the newly proposed method can achieve very close redistribution to the exact Shapley values but at a much lower (and practically feasible) computation cost. Furthermore, it performed similarly to the probabilistic, state-of-the-art approximation method while having smaller time complexity as well as other desirable characteristics for cost redistribution in energy communities.","Energy Community; Shared assets; Shapley value; Approximation algorithms; Smart grid; Stratification; Cost allocation","en","master thesis","","","","","","","","","","","","","",""

Much research has been performed on the mechanisms and methodologies behind their implementation and realisation. However, the efficiency and micro-structure of trading in such markets raise many important challenges. To analyse the efficiency of peer-to-peer energy markets, we consider two different popular approaches to peer-to-peer trading, i.e. centralised and decentralised and explore the economic benefits these models bring given optimal trading schedules computed by a joint schedule optimizer. In both these modes, benefits can be realised mainly due to the diversity in consumption behaviour and renewable energy generation between prosumers in an energy community.
This diversity decreases quickly as more peer-to-peer energy contracts are established and more prosumers join the market, leading to significantly diminishing returns. In this work, we aim to quantify such effects using large-scale real-world data from two trials in the UK, i.e. the Low Carbon London project and the Thames Valley Vision project.
We show that only a small number of peer-to-peer contracts and a fraction of the prosumers are needed to realise the majority of the Gains from Trade.
One assumption, based on experience with projects with various European cities, is that cities—their administrations and other stakeholders—generally have insufficient understanding of how to gain and maintain control over the complex process of the energy transition with its multiple actors and diverse objectives and responsibilities.
Another suggested reason is the lack of appropriate approaches, strategies, and methods to guide the energy transition in formulating clear targets and intermediate steps of mainly technical and spatial interventions. These, however are currently under development, and are being tested in cities across the continent—such as in Gothenburg, London, Rotterdam, Cologne, and Genova within the EU project Celsius (www.celsiuscity.eu), and in Amsterdam and Grenoble, for the EU project City-zen (www.cityzen-smartcity.eu)—with promising results so far.
The main research question underlying this chapter is: How can cities be supported in their energy transition toward carbon neutrality?
We will describe the development of approaches, strategies, and methods for the urban energy transition, their background and theoretical basis, and present urban case studies where they were applied. Finally, an outlook will be given for methodological developments in the near future.","Urban Studies; Energy communities; methods","en","book chapter","Elsevier","","","","","Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.","","2019-02-24","","Architectural Engineering +Technology","Landscape Architecture","","",""

Accordingly, local energy initiatives are emerging and increasing number of the business models are focusing on the end-users. In this context, Integrated community energy systems (ICESs) are emerging as a modern development to reorganize local energy systems allowing simultaneous integration of distributed energy resources (DERs) and engagement of local communities. With the emergence of ICESs new roles and responsibilities as well as interactions and dynamics are expected in the energy system. With this background, this thesis aims to understand the ways in which ICESs can contribute to enhancing the energy transition.
This thesis utilizes a conceptual framework consisting of four institutional and three societal levels in order to understand the interaction and dynamics of ICESs implementation. Current energy trends and the associated technological, socio-economic, environmental and institutional issues are reviewed. The developed ICES model performs optimal planning and operation of ICESs and assesses their performance based on economic and environmental metrics. This thesis demonstrates the added value of ICESs to the individual households, local communities, and the society. As the added value of ICESs is impacted by the institutional settings internal and external to the system, a comprehensive institutional design considering techno-economic and institutional perspectives is necessary to ensure effective contribution of ICESs in the energy transition.
