Can an energy only market enable resource adequacy in a decarbonized power system?: A co-simulation with two agent-based-models

Sanchez Jimenez, I.J. (author), Ribo-Perez, D.G. (author), Cvetkovic, M. (author), Kochems, J. (author), Schimeczek, C. (author), De Vries, Laurens (author)

Future power systems, in which generation will come almost entirely from variable Renewable Energy Sources (vRES), will be characterized by weather-driven supply and flexible demand. In a simulation of the future Dutch power system, we analyze whether there are sufficient incentives for market-driven investors to provide a sufficient level of...

Risk vs. restriction—An investigation of capacity-limitation based congestion management in electric distribution grids

Hennig, R.J. (author), De Vries, Laurens (author), Tindemans, Simon H. (author)

Electrification of energy end-uses brings an increasing load on electric distribution grids with load peaks that can cause network congestion. However, many new end-uses like electric vehicles, heat pumps, and electrified industrial processes have some flexibility to move their power consumption away from peak times. Congestion management...

Enhancing flexibility and strength-to-weight ratio of polymeric stents: A new variable-thickness design approach

Khatami, Mohamad (author), Doniavi, Ali (author), Abazari, Amir Musa (author), Fotouhi, M. (author)

This paper presents a new design strategy to improve the flexibility and strength-to-weight ratio of polymeric stents. The proposed design introduces a variable-thickness (VT) stent that outperforms conventional polymeric stents with constant thickness (CT). While polymeric stents offer benefits like flexibility and bioabsorption, their...

Flexibility Framework With Recovery Guarantees for Aggregated Energy Storage Devices

Evans, Michael (author), Tindemans, Simon H. (author), Angeli, David (author)

This paper proposes a framework for the procurement of flexibility reserve from aggregated storage fleets. It allows for arbitrary tree structures of aggregation hierarchy, as well as easily implementable disaggregation via broadcast dispatch. By coupling discharge and recovery modes, the proposed framework enables full-cycle capacity to be...

Coordination Strategies for Reducing Price Volatility in Local Electricity Markets

Chakraborty, S.T. (author)

With increasing renewable energy and cross-sectoral electrification price volatility is increasing. Flexibility through demand-side management and electric storage has the potential for reducing price volatility. In this thesis, using duality theory the flexibility required for constraining price to a maximum limit is quantified. <br/...

Synchromodal transport planning with flexible services: Mathematical model and heuristic algorithm

Zhang, Y. (author), Guo, W. (author), Negenborn, R.R. (author), Atasoy, B. (author)

As a critical feature of synchromodal transport (ST), service flexibility plays an important role in improving the utilization of resources to reduce costs, emissions, congestions, and delays. However, none of the existing studies considered flexible services under the framework of synchromodality. This paper develops a Mixed Integer Linear...

Aggregator's business models in residential and service sectors: A review of operational and financial aspects

Okur, Ö. (author), Heijnen, P.W. (author), Lukszo, Z. (author)

Flexibility coming from consumers in residential and service sectors has received significant attention to deal with uncertainty and variability of renewable energy sources. Since these consumers are too small individually to participate in the electricity markets, their assets can be pooled by an aggregator. The aggregator can implement...

Electricity Markets for DC Distribution Systems: Locational Pricing Trumps Wholesale Pricing

Piao, L. (author), De Vries, Laurens (author), de Weerdt, M.M. (author), Yorke-Smith, N. (author)

DC distribution systems are a promising alternative to existing AC distribution systems. They connect customers to local energy sources without conversion, thus reducing power losses. However, the unique features of DC impose strict requirements for system operation compared to AC. Within the context of a liberalized energy market, this...

Benchmarking Flexible Electric Loads Scheduling Algorithms

van der Linden, J.G.M. (author), Lane, N.R. (author), de Weerdt, M.M. (author)

Due to increasing numbers of intermittent and distributed generators in power systems, there is an increasing need for demand responses to maintain the balance between electricity generation and use at all times. For example, the electrification of transportation significantly adds to the amount of flexible electricity demand. Several methods...
