基于麻雀搜索算法的梯级泵站优化调度OA北大核心CSTPCD

Aimed at the problems of low operating efficiency and high energy consumption loss,an optimal scheduling model of cascade pumping stations is developed.This model adopts the sparrow search algorithm(SSA)of strong searching ability and high exploratory accuracy,and compares and selects its two parameters:safety threshold and scout ratio.Then,based on this algorithm,we formulate a new optimal scheduling method for cascade pumping stations,and apply it in the case study of a three-stage pumping station in the Miyun Reservoir regulation and storage project.The results show that under three different flow conditions,compared with the current scheme,the system efficiency of the optimized scheme obtained by the particle swarm optimization(PSO)and Pareto-archived(GA)algorithm are increased by 0.03%-0.18%,and the annual operating cost is saved by ¥9,700-¥69,500.More prominent is the SSA optimized scheme in ameliorating the two indexes mentioned above,which can achieve an efficiency increase of 0.98%-1.20%and an annual operating cost saving of ¥369,000-¥443,900.This verifies the feasibility and efficiency of SSA in the optimal scheduling of cascade pumping stations,along with its application to the scheduling as a reasonable and reliable method.
