摘要：

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. © 2016, Electric Power Automation Equipment Press.
