基于调频贡献率的调频辅助服务结算方法

Settlement Method for Frequency Modulation Auxiliary Service Based on Frequency Modulation Contribution Rate

调频辅助服务是电力市场中辅助服务市场交易的重要组成部分,已成为我国电力市场改革研究的重点。围绕调频辅助服务结算问题,基于我国现行的调频辅助服务考核三项指标提出了调频贡献率指标。以量化发电机组提供调频辅助服务过程中的贡献程度,以指标为核心构建基于调频贡献率的调频辅助服务结算方法。最后基于我国某电网实际数据构造算例,验证了所提出方法的有效性。

Frequency modulation auxiliary service (FMAS), an important part of auxiliary service market transactions in the power market, has become a research focus in power market reform in China. Aiming at FMAS settlement, frequency modulation contribution rate index was proposed, based on the three currently valid FMAS evaluation indexes in China, to quantify the contribution degree during FMAS of the generator unit. Using this index as core, an FMAS settlement method was built up on the basis of frequency modulation contribution rate. Finally, the validity of the proposed approach was verified, based on an actual data structure for a power grid in China.
