电力市场无功发电成本与补偿

无功功率服务是电力市场辅助服务的一个重要组成部分。而发电厂的无功电价又是无功市场辅助定价的基础。对发电厂的无功生产成本进行了探讨．首次提出将发电厂无功电价划分为无功容量电价和电量电价，并通过算例证明无功辅助服务在电力系统功率传输中的重要作用。研究表明发电厂的无功服务应得到一定的经济补偿，使其由自觉地维持电力系统的安全和稳定远行。

Reactive Power Generation Costs and Compensation in Electricity Market

Reactive power service is a key component of power market ancillary service, and reactive power price in the generation side is the base of reactive power market. In this paper, reactive power generation costs are discussed, which are decomposed into two parts: reactive capacity price and reactive power production price. The method is tested on the three-bus system. The results demonstrate that reactive ancillary service plays an key role in active power transmission. Research shows that with a reasonable economic compensation, generators will act to maintain security and stability of the system on its own initiative.
