摘　　要：发电侧和需求侧资源的优化配置不仅可提高系统运行的经济性,还可减少资源的浪费和污染物的排放,实现社会效益的最大化。根据需求侧可中断负荷可以参与系统备用的思想,考虑发电机组污染物排放费用,建立了一种基于最优潮流的主备用资源联合优化模型,研究了按发电机组停运确定系统最优备用容量以及可中断负荷参与系统备用对市场运行费用的影响。IEEE14节点算例表明,按发电机组停运确定系统备用容量减少了备用成本,优化了备用容量分布;可中断负荷参与备用虽然增加了系统备用成本,但减少了污染物排放费用,降低了系统总运行成本。Optimal configuration of the resources between supply and demand sides,can enhance the economy of power system,and reduce resource wasting and pollution discharging,and then realize maximum social benefits.Considering the cost of units＇ pollution emission,an energy and the power flow （OPF）model for joint optimal dispatch between host and reserve resources is proposed based on the methodology that interruptible loads （ILs） could participate in system reserve.The power market total operational cost is studied when optimal system reserve capacity is determined with generator outages and ILs participate in system reserve.The results of IEEE 14-bus system indicate that the reserve cost is reduced and distribution of reserve capacity is optimized when system reserve capacity is determined with generator outages.It also asserts that the total operational cost and pollution cost are reduced,except that the payoff for system reserve is augmented.
