Integration and energy management of large-scale lithium-ion battery energy storage station

The battery energy storage system can provide flexible energy management solutions that can improve the power quality of renewable-energy hybrid power generation systems. This paper firstly introduced the integration and monitoring technologies of large-scale lithium-ion battery energy storage station (BESS) demonstrating in SGCC national wind/PV/BESS and trans. demonstration project in Zhangbei, Hebei province, China. Then, the SCADA platform and battery energy management system (BEMS) used for the BESS have been presented. Some experiments and applications results obtained from the demonstration project have also been discussed to verify the effectiveness of the proposed energy management strategy.
