区域电力市场阻塞管理方法评述

Review of congestion management methods in regional power markets

电力市场化改革要求开放本地市场,开展跨区交易,促进竞争,其主要目的是提高市场效率,降低电价。但是,跨区交易同时也带来了一些重要问题,区域间的阻塞就是一个不可忽视的问题。对近年来国外提出的跨区域阻塞管理方法进行评述,比较了他们的特点,从中得出了一些结论,为进一步研究跨区交易的输电服务、制定合理的跨区交易的输电价格提供参考。并对我国的跨区域阻塞管理提出一些建议。

With rapid growth of the power market reform, the borders opening, inter-regional trade developing, and competition promoting are required in order to increase market efficiencies and decrease electricity prices. However, some unavoidable problems are also brought forward, such as inter-regional transmission congestion. In the paper, the existing methods of managing inter-regional congestion abroad are reviewed, their characteristics compared and some meaningful conclusions reached, which can be used to study inter-regional transmission services and make sound inter-regional transmission pricing. Some suggestions for the inter-regional congestion management in domestic are given in the end.
