Development of Optimal Power Flow for the Ancillary Service of Reactive Power Generation under Restructuring Environment

전력산업 구조개편 환경 하에서 무효전력 보조서비스 운용을 위한 최적조류계산법 개발

Under restructuring, not only real power pricing but also reactive power pricing is important for the system operation Especially, making a reasonable reactive power pricing is becoming more important than any other time. In this paper, the authors set a proper power factor and price the portion of the reactive power generation that exceeds the power factor. To apply this method to an optimization problem, we developed optimal power flow based on interior point method. By using this IPM for the power system, the System operator can use this strategy for reactive power generation pricing and also the Generators can got the motivation to generate reactive power.
