Real-time control and monitoring technologies used for multi-type energy storage laboratory in Zhangbei

Supervisory Control and Data Acquisition (SCADA) and the energy management system (EMS) have been used extensively in power generation systems. This paper presents the design and application of a novel SCADA and battery EMS (BEMS) for a multi-type battery-energy-storage system (BESS) tested at the State Energy Smart Grid Technology R & D Center of the China Electric Power Research Institute (CEPRI) located in Zhangbei, Hebei province, the People´s Republic of China (PRC). The realtime SCADA and BEMS were developed based on web technology and TCP/IP communication networks. A Zhangbei multi-type energy-storage laboratory was built to combine a 1 MW/1h lithium-ion BESS, a 0.65 MW/4h lithium-ion BESS, a 500 kW/2h Vanadium Redox Batteries (VRBs) energy-storage system, a 700 kWh lead-acid BESS, and other energy storage systems. Control strategies for the hybrid wind/BESS power system and its application to the laboratory were formulated based on the experimental results for several typical applications of a large-scale BESS.
