Problems solved by technology

This method can select the PSO algorithm to control the charging and discharging of energy storage, but the disadvantage of the PSO algorithm is that it needs multiple iterations to find the optimal solution, and the obtained solution is not the only one. The results obtained by using this algorithm are different each time, and the calculation large

Description

Technical field [0001] The present invention relates to the field of light recharge control techniques of electric vehicle charging station, and more particularly to control methods, systems, devices, and media for energy storage and discharge of light storage charger. Background technique [0002] Energy crisis and environmental pollution are important issues facing the current social development. Electric vehicles, renewable energy power generation, and energy storage technology have energy-saving and environmentally friendly features. It is an important part of the future intelligent grid system. At the same time, the electric load is increasing. The existing equipment capacity of distribution network cannot meet demand, and the peaks of the load also gradually intensifies. For the imbalance of supply and demand in power system, the peak power shortage gives local residents' normal life and economic industry development A serious impact. Therefore, the problem of supply and de...
