摘要(Abstract)：

基于模块化多电平换流器(modularmultilevel converter,MMC)的超级电容储能系统(super capacitor energy storagesystem,SCESS)用作电能路由器(electricalenergy router,EER)前端接入中压配电网时,由于其储能子模块(energysub-module,ESM)众多,储能容量利用率受限于各ESM荷电状态(stateofcharge,SOC)。针对现有SOC均衡控制策略的不足,该文在对MMC-SCESS数学建模的基础上,引入SOC平衡因子概念,并提出基于相间、上下桥臂、桥臂内的三级改进型SOC均衡控制策略。仿真研究表明,该文所提控制策略提升了系统鲁棒性和动态性能,尤其适合于未来能源系统中EER应用。
