Market Signals as Adequacy Indicators for Future Flexible Power Systems

De Vries, Laurens (author), Sanchez Jimenez, I.J. (author)

Existing indicators of electricity system adequacy need to be supplemented with economic performance indicators. As power systems are decarbonized, energy storage technologies are being developed and demand is becoming more flexible. Reliability standards need to reflect the price elasticity of these sources of flexibility. During scarcity...

What is a good distribution network tariff?—Developing indicators for performance assessment: Developing indicators for performance assessment

Hennig, R.J. (author), Ribo-Perez, D.G. (author), De Vries, Laurens (author), Tindemans, Simon H. (author)

The adoption of distributed energy resources such as PV cells, electric vehicles and batteries in electric grids is increasing steadily. This brings new challenges for distribution networks. The current network tariffs were not designed for these types of usage and, in many cases, they are not adequate anymore. Thus, many new tariff frameworks...

Participation of active consumers in the electricity system: Design choices for consumer governance

Pelka, S. (author), Chappin, E.J.L. (author), Klobasa, M. (author), De Vries, Laurens (author)

Household electricity use has an increasing impact on the overall energy system. Numerous proposals have been made to support households to consume electricity in a system-friendlier manner. By breaking these proposals down into functions and how they are performed, this paper identifies four distinctive governance designs: energy communities,...

Market Failures in Local Flexibility Market Proposals for Distribution Network Congestion Management

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

The steady uptake of PV cells and high-power flexible loads such as electric vehicles (EVs) and heat pumps can lead to localized network congestion, if their power consumption or feed-in is not controlled well. One potential way that has been proposed to manage this congestion, are so-called Local Flexibility Markets. It is often argued, that...

Making the most of short-term flexibility in the balancing market: Opportunities and challenges of voluntary bids in the new balancing market design

Poplavskaya, K. (author), Lago, Jesus (author), Strömer, Stefan (author), De Vries, Laurens (author)

Electricity balancing is one of the main demanders of short-term flexibility. To improve its integration, the recent regulation of the European Union introduces a common standalone balancing energy market. It allows actors that have not participated or not been awarded in the preceding balancing capacity market to participate as voluntary...

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...

Agent-Based Modelling of EU Energy and Climate Policy: Investment, Uncertainty and Policy Imperfections

Chappin, E.J.L. (author), De Vries, Laurens (author)

We simulate climate and energy policy for the EU using a flexible and modular agent-based modelling approach, we named Energy Modelling Laboratory (EMLab). The agent-based model focuses on investment in power generation and studies long run effects of various interacting European energy policies, and incorporates differences between countries....

Effect of market design on strategic bidding behavior: Model-based analysis of European electricity balancing markets

Poplavskaya, K. (author), Lago, Jesus (author), De Vries, Laurens (author)

Market-based procurement of balancing services in Europe is prone to strategic bidding due to the relatively small market size and a limited number of providers. In the European Union, balancing markets are undergoing substantial regulatory changes driven the efforts to harmonize the market design and better align it with the goals of the...

A coordination mechanism for reducing price spikes in distribution grids

Chakraborty, S.T. (author), Verzijlbergh, R.A. (author), Baker, Kyri (author), Cvetkovic, M. (author), De Vries, Laurens (author), Lukszo, Z. (author)

Recently, given the increased integration of renewables and growing uncertainty in demand, the wholesale market price has become highly volatile. Energy communities connected to the main electricity grid may be exposed to this increasing price volatility. Additionally, they may also be exposed to local network congestions, resulting in price...

Integration of day-ahead market and redispatch to increase cross-border exchanges in the European electricity market

Poplavskaya, K. (author), Totschnig, Gerhard (author), Leimgruber, Fabian (author), Doorman, Gerard (author), Etienne, Gilles (author), De Vries, Laurens (author)

The zonal electricity market design in the Central Western European electricity market relies on redispatching generation units after market closure to manage congestion within bidding zones, while congestion between the zones is handled using flow-based market coupling. The combination of internal congestion in the meshed European network...

Capacity Subscription Tariffs for Electricity Distribution Networks: Design Choices and Congestion Management

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

Residential distribution networks in Europe are undergoing rapid changes. As high-power flexible loads, such as electric vehicle (EV) chargers, become more prevalent, the risk of network congestion increases. This is exacerbated by tariff structures which do not give incentives to limit simultaneous power consumption. Network charges in this...

Markets for Direct Current Distribution Systems: Towards Energy-based vs Flex-based Designs

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

Direct Current Distribution System (DCDS), a promising alternative to existing AC systems, connect customers to DC energy sources without AC/DC conversion. The unique features of DC, including the power-voltage coupling effect, impose different requirements to DCDS operation compared to AC. Addressing a liberalized energy market, this paper...

Trading power instead of energy in day-ahead electricity markets

Philipsen, R.M. (author), Morales-Espana, G. (author), de Weerdt, M.M. (author), De Vries, Laurens (author)

Day-ahead electricity markets are inefficient due to their coarse discretisation of time and their representation of electricity production and consumption in energy per time interval. This leads to excessive costs and infeasible schedules in the market clearing results. Some real-world systems have increased the resolution to improve accuracy,...

Electricity Markets for DC Distribution Systems: Design Options

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

DC distribution systems (DCDSs) are a promising alternative to AC systems because they remove AC-DC conversions between renewable sources and loads. Their unique features compared to AC include low system inertia, strict power limits and power–voltage coupling. In a liberalised electricity market, merely applying an AC market design to a DCDS...

Aligning prosumers with the electricity wholesale market: The impact of time-varying price signals and fixed network charges on solar self consumption

Klein, Martin (author), Ziade, Ahmad (author), De Vries, Laurens (author)

PV-battery systems are currently not operated in an energy system optimal way as their operation heuristic (maximization of self-consumption) is generally unaffected by competitive market signals. To evaluate potential regulatory intervention, we propose a market alignment indicator which measures the relative economic efficiency of a prosumer...

The impact of weather and of batteries on the investment risk for backup gas power plants in a largely renewable energy system

Pelka, Sabine (author), De Vries, Laurens (author), Deissenroth, Marc (author)

With an increasing wind and photovoltaic share, the German generation mix becomes more weather-dependent. Backup technologies can help to bridge scarcity moments. These rare moments with high prices are the main events for their cost recovery. However, the uncertain revenue flow combined with long payback periods leads to high investment...
