摘　　要：定义了面对负荷水平的价格持续曲线和面对考察期内所有负荷的平均价格持续曲线。依照该定义,给出了考虑发电机组强迫停运和机组报价随机性的价格持续曲线的计算方法。该方法通过用等效机组替代发电机组的容量块,从而便于采用电力系统随机生产模拟的方法计算边际电价的概率和价格持续曲线。该方法具有计算速度快且概念清晰等优点。将该算法应用于一个PJM电力市场的计算算例,计算结果说明了文中方法的优越性。In view of the load level,the price duration curve（PDC） is defined.On this basis,the definition of the average PDC under all loads in the study period is given.In accordance with the definition,a calculation method of PDC is proposed by taking account of unit forced outage and unit stochastic bidding.By substituting the equivalent units for the capacity block of generating units,this method makes it possible to obtain the probability of marginal price and PDC based on the power system probabilistic production simulation.This method is characterized by conceptual clarity,flexibility and time saving.Finally,an illustrative case study of PJM electricity market is presented.
