多区域互联系统最优无功价格研究

提出了一种研究多区域互联系统优化无功价格的方法。系统内的无功支持除取有减少网损和改善电压安全性外，还能增加系统向外传送功率的能力，从而获得巨大的经济效益。提出以无功支持取得经济效益的大小来决定多区域互联系统的无功价格。并以３区域互联的ＩＥＥＥ１１８节点系统为例，进行了相应的计算和分析。

STUDY OF REACTIVE POWER PRICING IN MULTI-AREA POWER SYSTEMS

This paper presents an approach to study the price of reactive power support service in the multi\|area power system.In addition to reducing the costs and modifying voltage security,the VAR support in transmission system can increase the transfer capacity and thus increase power delivery of tie\|lines.The increasing of power delivery on tie\|lines means the great economic benefits from applying VAR support service.Therefore the VAR price can be determined by calculating these economic benefits from increasing power delivery of tie\|lines in the competitive environment with multi\|areas.The proposed VAR pricing scheme is tested on IEEEE 118\|bus system.Which is divided into three areas.The detail results and benefit\|cost analysis are given in the paper.
