ACTIVE POWER CONTROL METHOD OF PLURAL ENERGY STORAGE DEVICES FOR GRID CONNECTION OF INTERMITTENT GENERATION

摘要

PURPOSE: An active power control method of a plurality of energy storage devices for system access of an intermittent energy source is provided to control optimal active power through an objective function. CONSTITUTION: An objective function for optimal active power control of a plurality of energy storage devices is defined(S21). A solution of the objective function is extracted to satisfy a constraint condition with respect to output power and SOC(State of Charge) of a plurality of the energy storage devices and constraint condition related to a ramp rate limit regulation required for system access is calculated(S22). The optimal active power with respect to a plurality of the energy storage devices is estimated by calculating the solution of the objective function(S23).
