Multi energy storage SoC equilibrium strategy based on the variable regulating factor
In response to the problem of inconsistency of the state of charge between multiple groups of energy storage units of the Energy Storage DC microgrid. The paper proposes a multi -energy storage SoC dynamic balance strategy based on the the variable regulating factor, related the drooping coefficient of the ESU with the arccotangent function of the SoC. The drooping coefficient can change with the change of the SoC to a certain range to achieve the dynamic balance of multiple sets of energy storage SoC, design change factor m to speed up the SoC equilibrium speed between ESU. At the same time, the introduction of virtual voltage drop compensation links, dynamic elimination of the effects of line impedance on the current distribution accuracy.Simulation results verify the prpposed control strategy can achieve SoC equilibrium between multiple sets of energy storage units and effectively improve the SoC equilibrium speed.
