摘要： The present invention relates to a state of charge (SOC) management system of an energy storage device, the system comprising at least one energy storage device, wherein the SOC management system of the energy storage device manages SOC of the energy storage device by performing P-f (active power-frequency) droop control on the basis of a droop coefficient, a reference frequency, and a dead band, which determine the output of each energy storage device.
