Short-term Optimal Scheduling Method of Cascade Pumping Stations in Water Conservancy Projects Based on Particle Swarm Optimization Algorithm
This paper points out that cascade pumping stations in water conservancy projects are a complex and changeable system,and their operation involves the cooperative work among multiple pumping stations,but these relationships are often simplified,reflecting that the dynamic characteristics of pumping stations and the changes of actual operating conditions are too one-sided,resulting in large energy consumption of the generated dispatching scheme.Therefore,this study discusses the short-term optimal scheduling method of cascade pumping stations in water conservancy projects based on particle swarm optimization algorithm.The characteristics of cascade pumping stations in water conservancy projects are deeply analyzed,including the relationship between pump flow,lift and rotation speed,and the method of determining the working point of the pumping station;with the main goal of reducing energy consumption,the objective function of short-term operation of the pumping station is constructed;the relevant constraints are set,and particle swarm optimization algorithm is used to solve the objective function,so as to achieve the optimal scheduling strategy with the overall energy optimization as the goal.The experimental results show that under the same experimental conditions,the short-term optimal scheduling method of cascade pumping stations in water conservancy projects based on particle swarm optimization algorithm is the best in energy consumption,which is helpful to guide the operation of pumping stations more accurately.
