摘要：

Inconsistent State of Charge (SOC) of parallel Distributed Energy Storage (DES) can cause issues in microgrid stability and energy storage battery lifespan when using conventional Droop with fixed droop coefficients. DES with low SOC value may discharge prematurely and exit from operation, disrupting the microgrid's stable operation. To address this, this paper proposes an adaptive Droop control strategy based on dynamic correction coefficients that consider the local SOC of each DES and coordinate their output, to maintain stable microgrid operation. Its efficacy is confirmed through simulations on the PSCAD/EMTDC platform.
