摘　　要：针对能量路由器储能需求,提出利用其自身拓扑结构中的桥臂电路充当储能系统的充放电接口,无需额外增加功率变换电路,灵活实现自储能。研究了自储能控制策略,并分析了控制性能。提出的自储能型能量路由器能实现输入端功率缺额时能源子网的电压稳定,并在能源子网离网切换时提供短时的能量供应,而且控制储能系统充放电的同时不影响桥臂电路对中线电流的控制。仿真研究了输入端电压深度跌落和能源子网分布式能源功率波动时的工况,验证了所提拓扑及控制策略的正确性和有效性。For energy storage requirements of energy router, a new approach with one of its bridge arms served as interface to connect energy storage system is proposed, eliminating additional power conversion circuit. Control strategy is designed and system performance is analyzed. Self energy storage based energy router （SESER） has ability of voltage stability in power vacancy and short time energy supply in time of energy subnet switched to off-grid mode. Neutral current control is not affected in charging and discharging processes. Simulation for voltage deep droop of input port and power fluctuation of distributed generation are carried out. Results verify validity and effectiveness of the proposed topology and its control strategy.
