摘　　要：高比例新能源背景下,建立与能量市场相适应的容量市场机制可以保障电力系统充裕性。文章从机组投资决策的角度出发,研究了高比例新能源下容量-能量市场耦合的机组投资决策行为,并分析容量市场机制的运行效果。文章提出了机组决策、容量市场和能量市场的三层优化投资决策模型,针对该模型难以直接求解的问题,提出了容量-能量市场解耦的分阶段循环迭代求解策略。最后,基于某省网实际数据,运用所提方法对比和分析了高比例新能源接入下单一能量市场和容量-能量市场耦合下的容量充裕性保障效果。In order to guarantee capacity adequacy for the power system with a high penetration of renewable energy resources,it is necessary to establish a capacity market mechanism that is compatible with the energy market.From the perspective of investment decision-making,this paper analyzes the efficiency of capacity market mechanism in the power system with high-proportion of renewable energy by studying supplier's investment behavior in capacity-energy market with high integration of renewable energy.Firstly,a three-layer optimization model is established for the investment decision problem,including unit decision-making,capacity market and energy market model.Then since the model is difficult to solve directly,a phased loop iterative solution algorithm is proposed,being able to solve the problem with the capacity and energy market decoupled.Finally,based on the actual data of a certain provincial network,this paper uses the proposed method to compare the effects of energy-only market and capacity-energy market on capacity adequacy for the power system with a high proportion of renewable energy.
