[Abstract]:The dynamic regulation of DC microgrid power is slow, and the impact load has a serious impact on the power quality of DC microgrid. In order to solve the problem of balancing supply and demand of impact power in DC microgrid, a compensation method based on hybrid energy storage is proposed. Based on the complementary characteristics of super capacitor and storage battery, a hybrid energy storage control strategy with reference current constraints and dynamic current distribution is proposed based on the traditional hybrid energy storage control strategy. On the premise that the limit value of battery current is not exceeded, the optimal distribution of impact power in hybrid energy storage unit is realized, which can prolong the battery life cycle. The dynamic response time of impulse power compensation in hybrid energy storage system is shortened and the problem of voltage fluctuation in drilling DC microgrid is solved. Simulation and experiment verify the effectiveness and feasibility of the proposed control strategy.
