摘要
近年来南方区域西电东送格局有所发展与变化,现行单一制电量输电定价已不能适应,为此提出了两部制输电定价机制。首先对西电东送线路按输电工程类型和价区进行划分,提出了输电工程投资分摊方法;在此基础上,计算各价区的年准许收入并测算单一制电量输电价格和两部制输电价格。最后,用南方区域2012年西电东送实际交易电量对两种输电定价机制进行了计算分析,结果表明,两部制输电定价有利于缓解输电量波动所导致的输电公司收入波动,同时能够提高受电方消纳西电的积极性,对促进西电东送可持续发展具有积极意义。
In recent years,with the development and alternation of the west-to-east power transmission in the southern region of China,the prevailing one-part transmission pricing cannot meet the requirements at the present as well as in the future.To address this problem,a two-part transmission pricing mechanism is presented.Specifically,types of power transmission projects and price zones of west-to-east power transmission are initially divided,and an approach of allocating the investment of power transmission projects among various price zones is proposed.On the basis,of above work,the annual permitted revenue for each price zone is calculated,and then the one-part transmission price and two-part transmission price are figured up.Finally,based on the actual trading electricity quantity of the west-to-east power transmission in 2012,the effects of the one-part transmission pricing and two-part transmission pricing are calculted and analyzed in detail.The results show that the two-part transmission pricing is better for maintaining a stable revenue level for the transmission company in case that the actual trading electricity quantity is significantly less or more than the planned.Meanwhile,it can provide more motivation to the eastern provinces for purchasing electricity from the western provinces,and the sustainable development of the west-to-east power transmission is promoted.
