Optimized SOC Control Strategy for Parallel Operation of Energy Storage Systems in Microgrids

The optimal control of energy storage systems is crucial for the operation of microgrids. This paper proposes an optimized control strategy for the parallel operation of energy storage systems in an AC microgrid, using the state of charge (SOC) of the storage systems as a criterion to modulate their power output. The control model was developed in MATLAB/Simulink, and the simulation results demonstrate that the control strategy enables rational energy distribution within the microgrid, thereby enhancing its flexibility and reliability while simultaneously extending the lifespan of the energy storage systems.
