电力市场环境下无功辅助服务

Reactive Power Ancillary Services in Electricity Market

作为电力市场辅助服务项目之一的无功辅助服务虽然研究的时间不长,但已成为当前研究的热点。为了使人们更加清楚地了解当前的研究进展,介绍了各国无功辅助服务获取方法,从投资和生产成本上详细分析了无功成本的构成,同时依据无功成本的不同以及无功的地域性,将当前无功电价的制定归为两类:无功的容量电价和电量电价,而电量电价又包括忽略无功生产成本的边际定价方法和考虑无功生产成本的边际定价方法以及基于区域市场的无功定价,指出了这些定价方法的缺点。另外回顾了当前四种无功资源价值评估方法和无功市场力的概念,以及当前FACTS设备对无功电价制定的影响。讨论了当前合适的无功市场模式,最后对展望了无功辅助服务研究的方向。

The acquirement methods of reactive power ancillary services in different countries are introduced. The construction of reactive power ancillary cost is analyzed from investment and production cost. The reactive power price is classed into two sorts according to its cost and local difference. They are reactive capacity price and volume electricity price. The defects of these pricing methods are discussed. Four reactive power valuation methods and concepts Of reactive market power are reviewed. The influence of FACTS devices on reactive power pricing methods is analyzed. The reactive power market mode is discussed.
