Integrated Power Generation Scheduling Compilation Method for Large-scale Small Hydropower Station Group

This paper presented a province-district integrated generation scheduling compilation method for large-scale small hydropower station group.The approach was developed to handle current problems of small hydropower: disorderly management,striking waste of water and seriously abandoned electricity.This proposed method standardized the generation scheduling compilation flow of small hydropower by the idea of hierarchic building and management based on the scheduling relation of small hydropower.The tie-line section security constraint was added into the flow and an adjusting original schedules procedure of overload section was proposed.By the closed-loop mode of reporting proposed generating curves,checking transmission section security,distributing coordinate generating curves,the accuracy of power generation scheduling of small hydropower was increased effectively.The method had been applied to the small hydropower management system of Yunnan power grid.The feasibility and effectiveness of this algorithm has been verified available by the practical engineering.
