摘要(Abstract)：

电力市场采用分时电价后,每个时段的负荷量将发生变化,同时会对负荷缺电成本以及可中断负荷赔偿费用产生影响,进而影响系统可靠性以及备用购买情况。针对分时电价对负荷缺电成本以及可中断负荷赔偿费用的影响,以每个时段的购买备用容量社会成本最小为目标,采用概率方法建立了计及分时电价影响的系统动态负荷备用购买模型,并通过算例对不同时段的最优负荷备用购买情况进行了研究。结果表明,社会成本在低谷时段较分时电价实施前有所增加,而高峰时段则有所减少。同时可中断负荷受分时电价影响,其购买量在低谷时段降为最低,高峰时段则为最多,所建模型可以较好地反映分时电价对负荷备用容量购买情况的影响。

关键词(KeyWords)： 分时电价;概率密度;可中断负荷;发电侧备用容量
