Market power monitoring and mitigation mechanism of spot market under new power system

Abstract

In recent years, with the continuous development of China's electric power spot market construction, the market power problem brought by the structure of China's power generation-side has gradually become severe, and has evolved as the focus issue in the process of power market reform. The injection of renewable sources and the participation of distributed generation resources have brought profound influence on the power system and the power market, and it is urgent to establish and complete the market power monitoring and mitigation mechanism of China's electricity spot market. This paper primarily discusses the market power monitoring methods and mitigation mechanisms, then introduces the mature experience of typical international power markets in market power monitoring and mitigation mechanisms. Secondly, this paper summarizes the existing power monitoring and mitigation mechanisms in China, and analyzes the development and challenges of market power monitoring and mitigation mechanism construction under the new power system. We aim to provide some reference for the evaluation, monitoring and mitigation of market power in a series of practical aspects.
