面向新型电力系统的市场化容量充裕性机制实践与建议OA

Capacity adequacy of power system is crucial for ensuring power system security and stability,as well as the stable operation of electricity markets.At present,China is in an accelerated transition phase of building a new power system,facing the dual challenges of coordinating energy structure adjustment and advancing market-based reform.The current energy-centric market system lacks market-based mechanisms to incentivize long-term system adequacy,which hinders the achievement of power and energy balance across multiple time scales in electricity markets.Accordingly,this paper first proposes a renewed connotation of capacity adequacy based on the operation characteristics of the new power system.Next,it reviews current practices of capacity adequacy mechanisms both domestically and internationally and analyzes the applicability of different mechanisms under evolving power system conditions.On this basis,a fundamental framework for establishing capacity adequacy mechanisms is proposed.Finally,it provides recommendations for developing capacity adequacy mechanisms tailored to the new power system,covering aspects such as mode selection,development pathways,and key issues in implementation.
