Aimed at the shortcomings of one single energy storage system in terms of power and energy demand, as well as the problems of low management efficiency and poor economy, the impact of energy storage filtering time constant on the working efficiency is analyzed, with a focus on the traditional hybrid energy storage crossover control method. In addition, a multi-mode coordinated control strategy based on the monitoring of state-of-charge (SOC) is put forward. By dynamically adjusting the filtering time constant and dividing the energy storage into different working areas, the flexibility of energy storage power allocation in DC microgrids is realized to improve the working efficiency. At the same time, according to the source-charge power difference and the SOC of energy storage, four operation modes are designed to optimize the source-charge-storage coordinated control strategy, so as to reduce the number of battery charging and discharging times and improve the system economy. The results of actual microgrid tests show that the proposed control strategy has a higher efficiency and better economy, indicating its value for engineering popularization and application.
