Coordination control system and method for direct-current power grid containing energy storage

The invention relates to a coordination control system and method for a direct-current power grid containing energy storage. The control system comprises a sending end control module, an energy storage power station control module, a receiving-end master station control module and a receiving-end slave station control module, wherein each control module generates a PWM pulse signal for controllinga corresponding converter according to the running state of the direct-current power grid containing energy storage and/or the running state of the receiving-end master station of the direct-currentpower grid containing energy storage, and controls the corresponding converter by using the PWM pulse signal. According to the technical scheme, when the system is in a steady state, it can be guaranteed that the direct-current voltage of the system and the power of each receiving end are stable and controllable and free of steady-state errors, all the converters can respond rapidly and when the direct-current power grid b
