An Optimization Model for Capacity Planning and Ordered Discharging of Centralized Charging Stations

In this paper, a new optimization model is proposed for capacity planning and ordered discharging strategies of centralized charging stations. The proposed method is divided into two stages: firstly, the operating states of the battery pack are analyzed at each moment by combining with the distribution modes, then the first stage planning can be processed, where the model aiming at minimizing the construction cost of centralized charging stations can be solved by simulated annealing particle swarm optimization (SAPSO); Next, in order to maximize the peaking effect of the centralized charging station, the cost function aiming at minimizing load variance is proposed, and the discharge power of each time can be obtained by using yalmip. Finally, simulation results are presented to verify the usefulness of the proposed method.
