Commodity: HK-ESGU Energy Storage Unit Controller
Product Overview:
HK-ESG As the connection bridge between EMS and energy storage units,HK--ESGU connects EMS upwards through LAN interfaces,connects PCS downwards through Ether CAT,real-time bus for real-time power control collects and stores data including but not limited to:battery information,distribution switch status,comprehensive protection information,transformer,fire protection and other dynamic environment Information,other instrument information,etc,and uploads EMS to the bus.HK-ESGU collects all PCS data in the aggregation group and combines them into a single PCS according to the relevant conversion basis model,upload the status of the energy storage unit to the EMS in a single PCS state quantity.HK-ESGU receives the EMS master modulation,and at the same time allocates the active and reactive power regulation of each PCS in real time according to the collected PCS and BMS information,and then distributes the regulation of teach PCS to each PCS at the same time.
