摘要
以我国水电主要受端华东电网为背景,提出了特高压直流水电和区内多电源混联的水火电系统短期协调控制方法,以多电网调峰为优化目标,耦合逐次关联搜索、改进切负荷以及直流水电网间协调分配方法和抽水蓄能电站状态交替搜索方法,优化水电、火电、直流联络线和抽蓄电站等电源出力,并以峰荷差异合理分配网间受电,满足多个省网调峰要求。所提方法已集成到华东网调水火电协调优化系统,并通过华东电网某年实际调度数据验证了方法的可行性和实用性。
With ECPG（East China Power Grid） as the main receiving grid of hydropower transmission,a method of short-term coordinated control is proposed for the hybrid hydro-thermal system with hydropower stations and conventional power plants,which takes the multi-grid peak-load regulation as its optimization objective,integrates the successive correlative search,the improved load shedding,the multi-grid coordinated DC hydropower dispatch and the alternate status search of pumped-storage stations into a framework to optimize the power outputs of hydropower stations,thermal power plants,DC lines and pumped-storage stations,and distributes the received power among multiple grids according to the peak-load differences to meet the requirements of multiple provincial grids for peak-load regulation. The proposed method is embedded into the coordinated hydro-thermal optimization system of ECPG and its feasibility and practicability are verified by the actual annual dispatch data of ECPG.
