                  摘 要:为缓解能源压力,减少环境污染,终端用户使用分布式电源的比重逐年增加。提出一种终端电能路由器拓扑,提供多类端口,可以灵活方便地接入光伏、储能、交流负荷以及不同电压等级的直流负荷;给出了系统控制策略和能量管理策略,实现并网运行模式和独立运行模式的统一控制,并将终端电能路由器运行状态划分为 5 种,实现了 5 种运行状态的灵活切换。通过MATLAB/Simulink 仿真验证,所提控制策略与能量管理策略实现了母线电压稳定和功率平衡,能够满足用户对电能质量的要求。

                  Abstract: In order to ease energy shortage and reduce environmental pollution, end-using of distributed generation is increasing year by year. In this paper, a terminal power router topology with multiple types of ports is presented which can easily access to photovoltaic, energy storages, AC loads and DC loads at different voltage levels. The strategies for system control and energy management are proposed to realize the unified control on both grid-connected operation and stand-alone operation. Additionally, the operation state of terminal power router is classified into five types in this strategy which can be switched flexibly. Finally, the proposed strategies are verified by simulation in MATLAB/Simulink that they could keep the voltage of busbar steady as well its power balanced and which meets users’ demands for power quality.
                  Key words: terminal power router; control strategy; energy management; power balance
