Abstract
The battery energy storage system (BESS) using modular multilevel converter (MMC) as interface converter could implement a direct connection to the grid as well as smooth the output power of renewable energy sources.For the large-scale battery energy storage system,it is a major concern of both industry and academic to extend the lifespan of it.To address this issue,this paper proposes a multi-time scale operational principle with three control levels employed.Different control objects are defined to each level and the output power of different battery packs are determined based on their relative state of health (R-SOH).Thus,the SOH of different battery packs are concentrated and the lifespan of whole system is prolonged subsequently.At last,both simulation and experimental results are proposed to validate the effectiveness and feasibility of this novel multi-time scale operational principle.关键词
