摘要
利用基于电量不足期望值贡献系数的方法,并结合可靠性灵敏度分析,将事故备用费用分摊到发电侧和输电侧,并形成了相应的发电侧和输电侧可靠性电价。利用模糊聚类分析方法,根据用户的可靠性服务综合指标要求,将系统中的用户划分为几个层次类别,对每层用户进行归一化处理并用一个虚拟用户来代表该层用户的可靠性服务要求,然后根据各层虚拟用户的可靠性服务要求购买可靠性服务备用并将费用分摊到各个虚拟用户得到用户侧可靠性电价。通过算例仿真表明,所提出的可靠性电价体系能够有效地实现可靠性服务的差别定价。
Utilizing the contribution coefficient based on expected energy not supplied （EENS） and combining reliability sensitivity analysis, the contingency reserve cost is allocated to generation side and transmission side, and corresponding reliability pricings at generation side and transmission side are formed. Using fuzzy clustering analysis and according to customers＇ requirement on comprehensive index of reliability service the custormers in power grid are divided into several categories belonging to different hierarchies; then the customers in each hierarchy are normalized and a virtual customer is designed to represent the reliability service requirement of custormers in this hierarchy; finally, according to reliability service requirements of virtual customers in different hierarchies the reliability service reserves are purchased and the cost of the bought reliability service reserves is allocated to all virtual customers to obtain the reliability pricing at customer side. The discriminating pricing of reliability service can be effectively implemeted by the proposed reliability pricing system.
