Section iii proposes a possible organization of a reactive power market, a regional reactive power market established according to the distribution of the load and the reactive supply. the regional reactive power market is composed of a reactive energy market based on marginal pricing and a reactive capacity market based on a reactive regulating capacity payment. the cases in section iv, based on the market organization proposals and the reactive bid structure previously presented, performed on a five - bus system and the ieee 14 bus system, are used to analysis the effects of active bid, voltage control and power factor on the reactive marginal price
本文首先回顧了電力市場發展的歷史和現狀；然後對市場中的定價方法和無功輔助服務的內容及特點進行了總結，並介紹了一些國家的無功輔助服務市場模式和交易方法；接著立足我國國情，提出了單邊開放電力市場下的無功市場框架：即根據負荷和無功源的分佈特點建立區域無功市場，各區域無功市場又由相應的無功電量市場和無功容量市場組成；並提出了該無功市場模式下的機組報價模型和基於報價的以系統總購電費用最小為目標的無功電價計算方法；最後用一個5節點系統和ieee14節點系統進行了實例分析，初步研究了發電機有功報價、系統電壓控制以及負荷功率因數對無功電價的影響，得出了一些有借鑒意義的結論。 -
