Abstract The invention discloses an improved hybrid energy storage coordination control method and an improved hybrid energy storage coordination control system. The method comprises the following steps of acquiring an active direct current component and a reactive direct current component of a three-phase alternating current; obtaining an effective active component of the alternating-current side current;calculating an effective reactive component of the alternating-current side current; calculating a dq-axis component of an alternating-current side voltage given value of a voltage source converter VSC, and converting the dq-axis component into an abc three-phase static coordinate system to obtain a three-phase alternating-current side modulation voltage given value; obtaining a driving signal ofthe voltage source converter VSC through a PWM modulation circuit, and controlling the on-off of a switching tube in the VSC. The invention further provides a corresponding system, computer equipmentand a computer-readable st
