摘要：

With the application of DC micro-grid in buildings and other DC applications, the problem of power quality has begun to receive attention. As the DC bus voltage is the only standard for the electric energy quality of the DC micro grid, this paper presents a control strategy based on hybrid energy storage to improve the DC bus voltage in DC micro grid. Taking advantage of the high power density of the Super capacitor and high energy density of the battery, the bus voltage is segmented to be managed based on Bus voltage deviation under different voltage conditions. The voltage stability of DC bus can be improved by two different energy storage control strategies. The correctness and feasibility of the proposed method are demonstrated by the simulation results based on Matlab/Simulink [1].
