Optimal Dispatching of Cascaded Hydropower Stations Based on Bat Algorithm
Hydropower as an important clean and renewable energy,how to realize the dispatching operation of giant scale cascaded hydropower stations which is gradually formed in our country is of great significance under the background of clean and low-carbon development.With the deepening of the hydropower development,the number of hydropower stations has continuously increased in one cascade.The traditional optimization algorithms,such as Dynamic Programming(DP)algorithm and Progressive Optimization Algorithm(POA),encountered the dimensions disasters and overlong calculation time,so that they were difficult to meet the requirement of optimization algorithm for the increasing number of cascaded hydropower stations.For this purpose,the Bat Algorithm(BA)was introduced to solve the optimization scheduling model of cascaded hydropower stations in this paper,and was applied to the optimization scheduling of the cascaded hydropower stations with Huanren hydropower station,Huilongshan hydropower station and Taipingshao hydropower station in the Hunjiang River.By comparing with the application results of Progressive Optimization Algorithm(POA),it showed the advantages of BA on computing speed and convergence,and the optimal result was satisfied.
