Comparative Study on Regulating Power Markets for Maintaining Stability and Flexibility of the Electricity Supply System

European Union (EU) countries try to integrate electricity markets to secure supply efficiently. The EU's most important task is to create a power system that can deal flexibly with fluctuations in renewable energy. In this research, we focus on the mechanism of regulating the power markets such that a physical security of supply is guaranteed. EU countries operate a variety of different regulating power market systems. Therefore, we compare the differences in regulating the power market system of each country and evaluate the influence of these differences, especially on maintaining a flexible power market.
