Research on Annual Power Balance and Short-term Optimal Scheduling Considering Abandoned Water Power

With the rapid growth of my country’s new energy installed capacity, the phenomenon of water abandonment, wind abandonment, and light abandonment in the power system has gradually intensified. Especially in areas rich in hydropower resources, the problem of water abandonment is particularly prominent. In order to effectively solve the problem of abandoned water and improve the utilization rate of hydropower, this paper studies the annual power balance and short-term optimal scheduling problem considering abandoned water. Firstly, this paper analyzes the current situation of water abandonment in power system at home and abroad and its impact on power grid operation, combined with the actual operation data of a hydropower station in China, constructs an annual power balance model, and adopts multi-objective optimization method to coordinate and optimize the power balance and water abandonment. The research shows that considering the abandoned hydropower, the waste of hydropower resources can be effectively reduced by reasonable power balance, and the regulation ability and power supply reliability of the power grid can be improved. This paper also combines the optimization algorithm of short-term dispatching to simulate and analyze the dispatching strategy under different load demands and water conditions. The results show that the optimized dispatching strategy can reduce the amount.
