变调节因子的不同容量锂电池储能系统能量控制策略OA

To achieve state of charge(SOC)balancing control and power allocation of energy storage units(ESUs)with different capacities,an energy control strategy with variable regulation factors for energy storage systems with different capacities is proposed.By establishing an exponential function that introduces a capacity factor,each ESU allocates output power according to its capacity ratio,while setting a dynamic adjustment factor to increase as the difference between the SOC of each ESU and the global SOC average decreases,solving the problem of the imbalance between maximum output power and equilibrium speed.To reduce communication pressure,a dynamic consistency algorithm is used to obtain the global average value and develop a control strategy in case of communication failure,so that the system can operate stably.Finally,the Matlab/Simulink simulation is conducted,and the results show that the proposed strategy has faster equalization speed and more accurate power allocation compared to the fixed adjustment factor SOC equalization strategy.
