现货市场中实现保供目标的容量补偿定价方法OA北大核心CSTPCD

To address the issue of installed capacity scarcity of power system on the power spot market,a capacity com-pensation pricing method is proposed to realize objective of capacity adequacy of power system.First,according to the power system reliability standard required by capacity adequacy,a decision-making model for the investment and retire-ment of generators is constructed based on the internal rate of return(IRR),and an iterative process of"Assessment of generators'revenue on the power spot market,assessment of generators'capacity compensation revenue,and decision-making for investment and retirement"is performed to determine the expected installed capacity of different types of generators on the market in the target year.Then,the reliability index in the target year is calculated,and the capacity compensation price is adjusted according to the difference between the reliability index and the standard until the sys-tem's reliability standard in the target year is satisfied by the power generation capacity margin.The result of a case study shows that the proposed pricing method can reduce the comprehensive electricity purchase cost on the basis of en-suring the power system reliability.
