电力市场中损耗分摊方法选择与比较研究

Research on losses allocation methods and their comparisons in electricity market

在电力市场环境下,输电服务起着非常重要的作用.针对如何处理伴随输电系统开放而带来的新问题,对联营与双边交易共存(P-B)市场模式下的损耗分摊问题进行了研究.首先对市场成员进行认定,将其划分为内部成员与外部成员;然后对不同类型的成员选用相应的损耗分摊方法.这种划分方式有利于确定市场成员的权利与责任,能够体现损耗分摊的公平性与合理性.IEEE-57母线标准测试系统和某实际系统的计算验证了所提方法的有效性.

Transmission service is playing an increasingly vital role in the modern power system. How to deal with the new problems accompanying open transmission access is becoming a hot spot of research. Losses allocation in a competitive electricity market with pool and bilateral (P-B) transactions is explored. Market participants are firstly divided into interior participants and exterior participants. Then corresponding losses allocation methods are selected for different types of participants. This method of division contributes to the determination of the individual participant′s right and obligation, which can reflect equability and reasonability when allocating the transmission losses. Capabilities of the proposed method are illustrated on the IEEE-57 bus system and a realistic power system.
