Solar-Storage Configuration of Bus Charging Station Considering Load Characteristics and Working Conditions
With the development of light-storage-charge integrated charging stations,how to reasonably determine the light-storage capacity on the basis of existing bus charging stations has become the focus.Therefore,this paper proposes a capacity allocation model for the charging station of optical storage buses that considers the load character-istics and operating conditions.Firstly,considering the charging load characteristics of the bus charging station,the threshold of the charging and discharging state of the energy storage is determined by the moving boundary method,and the more optimal operating conditions and operating conditions of the optical storage bus charging station are con-structed.Secondly,with the goal of maximizing photovoltaic utilization and minimizing system investment and operating costs,the particle swarm algorithm is used to optimize the solution to determine the optimal photovoltaic and energy storage capacity of the solar-storage bus charging station.Based on the actual operation data,an economic comparison is made between the solar-storage bus charging station considering the load characteristics and operating conditions and the unconsidered solar-storage bus charging station.The results show that more reasonable photovoltaic and energy storage capacity can be obtained by considering the load characteristics and operating condi-tions under the same configuration.
