        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
