Capacity Mechanisms: ensuring long-term system adequacy during the energy transition in the electricity market

Electrification by means of renewable energy sources in electricity production (RES-E) is a key strategy to meet global climate goals established in the Paris Agreement. The increasing share of RES-E as a result of this has significant implications on the functioning of the electricity system and the adequacy of the electricity market design, as...

Generating multivariate load states using a conditional variational autoencoder

For planning of power systems and for the calibration of operational tools, it is essential to analyse system performance in a large range of representative scenarios. When the available historical data is limited, generative models are a promising solution, but modelling high-dimensional dependencies is challenging. In this paper, a...

Market Signals as Adequacy Indicators for Future Flexible Power Systems

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...

A proof of concept for simulating long-term energy system development in a myopic investment detailed operational model: The case of system adequacy

In an energy-only market, private investors play a crucial role in realizing the security of supply. However, several specific characteristics inherent to his market design cause concern about whether this market design is suitable for system adequacy. Moreover, due to policy goals aimed at working towards low-carbon energy systems, these...

Assessing Energy Storage Requirements Based on Accepted Risks

This paper presents a framework for deriving the storage capacity that an electricity system requires in order to satisfy a chosen risk appetite. The framework takes as inputs user-defined event categories, parameterised by peak power-not-served, acceptable number of events per year and permitted probability of exceeding these constraints, and...

How do demand response and electrical energy storage affect (the need for) a capacity market?

To ensure security of supply and incentivize reliable investment in generation capacity, capacity markets (CMs) have been implemented or are being considered. However, demand response (DR) and electrical energy storage (EES) also contribute to system adequacy. In this paper, we analyse the change in the need for a CM if DR and EES are...

Regulatory Design of Capacity Remuneration Mechanisms in Regional and Low-Carbon Electric Power Markets

Capacity remuneration mechanisms (CRMs) are “climbing” regulatory agendas in all liberalised power sectors, especially in the European Union. CRMs are introduced to improve system reliability and to minimise power shortages to an economically efficient extent. These schemes will have a central role in future power systems. This PhD thesis...
