Cascade pump stations play a significant role in modern construction projects such as water diversion,irrigation,and ecological environment restoration.In order to promote the efficiency of cascade pump station operation and save operation costs,a scheduling method based on the Runge-Kutta optimization algorithm(RUN)is proposed.Considering a cascade pump station water diversion project,an optimization scheduling model is established with the goal of the highest overall efficiency.Compared with the current operating scenario,the results indicate that the scheme obtained by RUN can improve the operating efficiency by 0.73%and save operating costs by 271,195 yuan/a,which is better than the results obtained by the PSO and GA algorithms,confirming that the proposed algorithm is able to serve the optimization operation of cascade pump stations well.
