摘要(Abstract):

调频性能指标是机组参与电力市场调频辅助服务能力的重要参考,提升机组调频性能对稳定电力市场下系统频率具有重要意义。通过对浙江省电力现货市场4次结算试运行期间火电机组调频性能现状的分析,指出了导致目前火电机组调性能指标偏低的主要原因,提出了提高AGC(自动发电控制)速率设定、优化协调控制策略、综合分析“两个细则”、滑压曲线切换、加强运行管理、储能调频等改善机组调频性能的方法。应用结果表明,所采取的措施能够有效解决部分机组调频性能指标偏低的问题,并可增加火电企业电力市场调频辅助服务收入。
The frequency modulation performance index is an essential reference for the unit to participate in the auxiliary service capacity of frequency modulation in the power market. It is of great significance to stabilize the system frequency in the power market by improving the frequency modulation performance of the unit. By analyzing the current situation of frequency regulation performance of thermal power units during the four settlement and trial operation of electricity spot market in Zhejiang,this paper summarizes the main factors leading to the low frequency regulation performance index of thermal power units and proposes such means as improving AGC(automatic generation control)rate setting,optimizing coordinated control strategy,comprehensive analysis of the“Two Rules”,sliding pressure curve switching,energizing operation management and energy storage frequency modulation. The application results show that the above measures can solve the low frequency regulation performance index of some units to improve the income of frequency regulation auxiliary services in the power market.
