基于MATLAB/GUI的电动汽车充电站有序充放电优化调度仿真平台

为实现电动汽车充电站收益最大化以及充电站与配电网之间交互功率波动最小的目标,建立了基于MATLAB的图形用户界面(GUI)的电动汽车充电站有序充放电优化调度仿真平台。模型中的充电站分别采用分时电价、动态电价、节制放电三种电价方式,并通过动态自适应粒子群优化(DAPSO)算法进行调度,同时对比这三种电价对配电网负荷曲线的影响。利用MATLAB中的GUI建立了仿真平台界面,通过设置各个组件按钮的具体参数、属性以及回调编译m文件来实现优化调度,最后在MATLAB中形成可编译、操作的文件。该仿真平台可同时显示多种调度方案的结果,使其可视化和可编辑的优势更加突出,有利于集中呈现充电站优化调度的仿真结果。

Optimal Scheduling Simulation Platform for Orderly Charging and Discharging of Electric Vehicle Charging Station Based on MATLAB/GUI

To maximize earnings for the electric vehicle charging station and minimize the fluctuation of interaction power between a charging station and distribution network,a simulation platform for optimal scheduling of orderly charging and discharging of electric vehicle charging station was established based on MATLAB and GUI.The charging station adopted time-of-use electricity price,dynamic electricity price and controlled discharging,these three strategies,and conducted dispatching by dynamic adaptive particle swarm optimization(DAPSO)algorithm.Meanwhile,the influence of these three strategies on the load curve of the distribution network was compared.Simulation platform was established based on MATLAB GUI interface,and by setting the function of various control parameters and callback compilation m file to realize the function of the optimal operation,finally formed in MATLAB can manipulate files.The simulation platform can display the results of various scheduling schemes at the same time,and has the advantages of better visualization and editability,which is conducive to the centralized presentation of simulation results of optimal scheduling of the charging station.
