Growth in energy demand together with the expansion of variable renewables has significant implications for the future electricity system. The increased volatility from growing intermittent production requires new sources of flexibility at a much greater scale to help maintain system balance. In...

Electricity wholesale markets are undergoing rapid transformation due to the increasing share of distributed and variable renewable energy sources (vRES) penetrating the market. The increasing shares of stochastic wind generation bring along greater deviations between the real time power...

France wants to become carbon-neutral by 2050. Renewable energies and nuclear power are expected to make the main contribution to this goal. However, the average age of nuclear power plants is approaching 37 years of operation in 2022, which is likely to lead to increased outages and expensive...

We analyse the drivers of European Power Exchange (EPEX) wholesale electricity prices between 2012 and early 2022 using machine learning. The agnostic random forest approach that we use is able to reduce in-sample root mean square errors (RMSEs) by around 50% when compared to a standard linear...

The electricity price is the sensitive signal of the supply-demand balance and some other market incidents. The analysis of the price data can provide plenty of the market information. It is helpful for the participants to understand the market and improve future strategies. However, most of the...

This paper studies the bidding strategy of a Virtual Power Plant (VPP) in a market of energy and regulation service. The operation of distributed energy resources (DER) and battery energy storage inside the VPP is analyzed. A bidding strategy of the VPP including the spinning reserve contract...

To achieve the commitments to both carbon peaking and carbon neutrality, China should focus on those policies of significant impact on emissions reduction at the lowest cost. Launching the national carbon market with the power generation sector is a good start point in this direction. Since its...

Contracts for differences are widely discussed as a cornerstone of Europe’s future electricity market design. In this paper, we make three contributions to the debate. First, we summarize the dispatch and investment distortions that traditional CfDs cause. Second, we propose an alternative CfD...

Germany's energy transition is associated with increasing congestion in the electricity transmission grids due to increasing infeed from renewable energy sources, especially from wind turbine installation at the periphery in coastal areas. Here, regional differences in generation and demand lead...
