Research of Control Strategy of Storage Energy in Hybrid Integrated Energy Stations

In this paper, the structure of power supply was designed, and a hybrid integrated energy station (IES) system was introduced. The function structure of the battery energy storage system (BESS) was designed, the operation flowchart of the BESS was carried out. And the four operation modes of BESS were put forward, such as spread arbitrage mode, demand response mode, auxiliary frequency modification mode, and uninterrupted power supply mode. A control strategy of BESS according to step power price and BESS operation mode were discussed. Results of the simulation show that the designed control strategy of BESS with high performance and comprehensive energy efficiency in hybrid integrated energy station system.
