The battery energy storage system(BESS) can effectively suppress the influence of randomness and volatility of distributed generation on the power grid. Therefore, it is widely used in microgrid. Aiming at the overcurrent problem of BESS during the recovery stage of voltage drop fault, A low voltage ride through strategy using dynamic limiting and reactive power coefficient compensation is proposed to improve in this paper. Firstly, the typical topology and control strategy of BESS are given. Then, the causes of the over-current problem are analyzed during the fault recovery stage. Finally, the mathematical relationship between the terminal voltage and the limiting value of the outer loop PI controller is established, and an overcurrent suppression strategy is proposed. Furthermore, the effectiveness of the strategy is verified base on PSCAD/EMTDC. The results show that the proposed LVRT strategy can effectively solve the over-current problem of BESS during the recovery process.
