Abstract

Modular battery energy storage systems (MBESS) allow individual battery power control, with reduced voltage ratings of the converters, and enhanced system reliability. The power is shared amongst different battery modules based on the state of charge (SoC) of each module. In this paper, an adaptive power sharing control method is proposed for an MBESS that is connected to the DC bus voltage of a distributed generation system. The adaptation process considers the efficiency and balancing speed of the system at different battery loads. Simulation results (MATLAB/Simulink) are presented to compare the proposed systems performance in terms of balancing speed and efficiency, with conventional and adaptive power sharing methods.
模块化电池储能系统功率共享的自适应控制器
模块化电池储能系统(MBESS)允许单独的电池功率控制,降低转换器的额定电压,提高系统可靠性。根据每个模块的充电状态(SoC),功率在不同的电池模块之间共享。针对与分布式发电系统直流母线电压相连接的MBESS,提出了一种自适应功率共享控制方法。该自适应过程考虑了系统在不同电池负载下的效率和平衡速度。通过MATLAB/Simulink进行了仿真,比较了系统在平衡速度和效率方面的性能,并与传统的和自适应的功率共享方法进行了比较。
