摘　　要：在“碳达峰、碳中和”背景下,可再生能源的快速发展将进一步推动电源结构的优化转型,然而可再生能源出力的随机性和波动性对电网可靠供电、对新型电力系统的发电容量充裕性带来了严峻挑战。近年来,学术界对容量充裕性机制已开展不少研究,但尚未定量评估不同充裕性机制在引导系统最优容量方面的效果。为此,该文选取稀缺性定价、传统容量拍卖和引入可靠性期权的容量拍卖这三种容量充裕性机制,探究这些机制在确定性下引导系统最优容量的等价性及在系统停电小时数、机组出力的不确定性下对发电商收入的影响。最后,对我国电力市场容量充裕性机制的建设提出建议和关注点。Under the background of “carbon peaking and carbon neutrality”, the rapid development of renewable energy resources will further change the power supply structure.However, the randomness and volatility of renewable energy outputs bring severe challenges to capacity adequacy. Recent studies have been carried out on capacity adequacy mechanisms, but the effects of different adequacy mechanisms on guiding optimal capacity have not been quantitatively evaluated. This paper selected three capacity adequacy mechanisms: scarcity pricing, traditional capacity auction, and capacity auction with reliability options, explored the equivalence of these three mechanisms in inducing optimal capacity under certainty and the impact on supplier revenues considering the uncertainty of outage hours and generation outputs. Finally, suggestions and concerns were put forward to select capacity adequacy mechanisms in China’s electricity market.
