【Abstract】 Super capacitor energy storage(SCES) technology stands out conspicuously, its effect becomes more and more important in energy storage system of microgrid, because of its higher power density and longer service life. The characteristics of super capacitor are analyzed, super capacitor has many advantages, but because of the disadvantages, such as low energy density, high cost, it can’t be used in microgrid alone, which must be used in conjunction with the battery. The basic structure of the microgrid shows that there must be an energy storage system to restrain the power fluctuations frequently because of the distributed generations, which shows the importance of research on Microgrid energy storage system. The hybrid energy storage control strategy is analyzed, the strategy proves that through using super capacitor, battery can be effectively improved the work environment, reduced the charge and discharge frequently. Thus it shows the necessity of the application of super capacitor in microgrid. Finally, the results simulation verify the correctness of the above conclusion.更多还原
