【 摘 要 】

This paper study the structure and operating characteristic of the hybrid energy system which is made of super-capacitor and battery. The system is controlled by strategy of bus voltage following. The bus voltage can change the state from swings to stable quickly when load mutation occurs in the micro grid. The transient impact also can be reduced by this way. The passage set up the model of energy system and make an analysis by the software named MATLAB/Simulink. At last, the passage proves the correctness and the effectiveness of the control strategy and draws a conclusion that the transient impact can be inhibited which occurs in the bus voltage of energy system.
