摘　　要：西电东送对于加快中国能源结构调整、促进西部地区经济发展和实现资源优化配置有着重要的战略意义。随着西电东送电价水平的逐步提高,西电东送矛盾逐渐凸显。分存量和增量2个部分对"十三五"西电东送输电价格定价机制进行了研究。基于分层送电曲线提出了增量部分的两部制输电价格定价方案,确定了容量电费与电量电费比例关系,并采用峰荷比例法对容量电费进行分摊。测算分析了两部制输电价格机制对于送受端和输电公司的利益影响,以及保障曲线、协议曲线和超送曲线下的各方利益情况。测算分析表明,提出的分层送电曲线下的两部制输电价格机制,能够平抑输电公司的收益水平,激励送端增加送电量并提高受端接纳西电的积极性,对于解决西电东送落地电价缺乏竞争力问题有着重要的借鉴意义。West-to-east power transmission is of strategic significance for speeding up China＇ s energy structure adjustment and promoting the economic development and optimal allocation of resources of the western regions. Along with the gradual rise of the power price level, the problems of west-to-east power transmission are getting prominent. A study is made on the pricing mechanism of west-to-east power transmission during the ＂13th Five-Year＂ priod （2016-2020） in terms of stock and increment. A two-part transmission pricing mechanism of the incremental part is proposed based on the hierarchical power transmission curve, and the ratio between of the electrical capacity charge and power charge is determined, and the electrical capacity charge is apportioned with peak-load electricity capacity ratio method. An analysis is made on the impact of the two-part transmission pricing mechanism on the interests of power feeding and receiving ends as well as transmission companies. And the interests of the shareholders are also discussed respectively under guarantee curve, protocol curve and super delivery curve. It is concluded that the proposed two-part transmission pricing mechanism under the hierarchical electricity curve can stabilize the income level of transmission companies, and encourage the enthusiasm of both the feeding-end and the receiving-end respectively for increasing the generation capacity and receiving the western power. The proposed idea can be an important reference for solving the west-to-east power transmission pricing problems.
