南方区域跨省跨区电力交易偏差结算机制探讨

Discussion on the deviation and settlement mechanism of inter-provincial and inter-regional power transaction in southern region

偏差电量的处理是跨省跨区电力交易结算的关键环节,首先对国内外典型电力市场的偏差结算模式进行概述总结,然后分析了当前常用的3种偏差电量分摊结算方法,总结其优缺点,并分析随着南方区域市场的发展,当前偏差结算方法存在的问题。为做好与现货市场结算机制衔接,充分发挥市场定价作用,提出偏差电量单独定价结算方法,并给出偏差定价及偏差费用分摊机制设计。最后,根据南方区域市场不同发展阶段的结算要求,对偏差结算方法的选择,提出合理性建议,并对未来南方区域跨省跨区结算机制如何完善进行了展望。

The processing of deviation power is a key link in the settlement of power transactions across provinces and regions.Firstly,the deviation settlement models of typical power markets at home and abroad is summarized,and then the three commonly used methods for allocation and settlement of deviation power to summarize their advantages and disadvantages are analyzed.And the problems of the current deviation settlement method with the development of the southern regional market are analyzed.In order to connect well with the spot market settlement mechanism and give full play to the role of market pricing,a separate pricing and settlement method for offset power is proposed,and the design of offset pricing and offset cost allocation mechanism is given.Finally,according to the settlement requirements of different development stages of the southern regional market,the reasonable selection of deviation settlement methods is put forward,and the prospect of how to improve the inter-provincial and inter-regional settlement mechanism of the southern region is expected.
