英文摘要：

Taking into account the state of charge （ SOC） of energy storage system （ ESS） , a method waspresented to determine the distribution coefficient of ESS and conventional generator （CG） dynamically based onthe available regulation capacity, and an aggregative indicator was used to evaluate the relating effects and SOCmaintaining effects. The simulation results show the method proposed can improve the frequency regulation serviceand maintain the SOC within a desired range, providing technical support to the optimized operations of the grid.
