Abstract The paper deals with mathematical modelling and the control system for UltraFast Charging Stations (UFCS) based on DC micro-grid concept and Energy Storage System Integration to feed new Electrical Vehicles (EVs) at 800V DC in order to reach the EVs power requirement for charge-time less than 10 min. The UFCS integrates a battery energy storage system (BESS) to reduce the peak power of AC main grid, decoupling the dynamics of the DC charging station from the AC grid by means of its dedicated control system. Designing procedure and Control Strategy, based on Load Levelling power management, are dealt with numerical simulation results in Matlab-Simulink software, presented in order to verify UFCS performance and the charging station’s dynamics.

电动汽车超快充电站：动态建模、设计和控制策略

摘要 本文讨论了基于直流微电网概念和储能系统集成的超快速充电站 (UFCS) 的数学建模和控制系统，以 800V DC 为新的电动汽车 (EV) 供电，以满足电动汽车的电力需求。充电时间小于 10 分钟。UFCS 集成了电池储能系统 (BESS) 以降低交流主电网的峰值功率，通过其专用控制系统将直流充电站的动态与交流电网解耦。设计过程和控制策略，基于负载均衡电源管理，在Matlab-Simulink 软件中进行数值模拟结果处理，以验证UFCS 性能和充电站的动态。
