Existing low voltage ride-through (LVRT) control strategies for electrochemical energy storage do not take into account the dynamic characteristics of state of charge (SOC). This leads to over-discharge in low SOC scenarios. Thus this paper designs and introduces an adaptive regulation coefficient to characterize the effect of SOC on the output active current of the storage unit during the LVRT period. Then an LVRT control strategy for the electrochemical energy storage system is proposed by taking into account the dynamic characteristics of the SOC and the charging/discharging state. The control strategy is based on the voltage and frequency requirements of the grid-connected specification, and the adaptive regulation coefficients are quantitatively designed in combination with practical engineering applications, so that the active current output from the storage unit can be dynamically adjusted according to the SOC during a system fault. Simulation results show that this control strategy can effectively limit the active current output and slow down the discharge rate in low SOC scenarios, thus avoiding the risk of small-capacity and large-discharge-multiplication energy storage units quitting the operation because of SOC overrun, and reducing the SOC polarity difference between multiple energy storage units in the process of LVRT. The effectiveness of the proposed strategy is verified by comparing it with the conventional LVRT strategy.
