摘　　要：基于电力需求容量成本分摊的峰荷定价机制能有效避免交叉补贴的现象,有利于实现系统负荷容量的公平分摊。阐述了该机制的基本原理,构建了以社会净福利最大化为目标的目标函数,利用Kuhn-Tucker最优条件对模型求解,确定了使社会福利最优的用户可接受价格。通过算例验证了模型的合理性及算法的有效性。The peak-load pricing mechanism based capacity cost allocation of electric power demand can avoid phenomenon of cross-subside effectively and it is in favor of system load capacity sharing fairly.In this paper,the basic principle of peak-load pricing mechanism is elaborated.And the objective function is established for maximizing social net welfare.Then the model is solved with the Kuhn-Tucker optimal condition and the acceptable price for user is determined by maximizing the social welfare.Finally,an example shows that the peak-load pricing model is reasonable and the algorithm is effective.
