Abstract

To cope with the unstable output power of distributed generation systems, it is necessary to configure an energy storage device with a suitable capacity in the microgrid, and adopt appropriate control methods to achieve the output power of the smooth distributed power generation, so as to achieve the effect of peaking and filling the valley of the microgrid load. This paper proposes the method of applying the upper and lower limit constraint method and the weighted moving average control method to meet the access requirements of the microgrid, targeting the minimum energy storage configuration capacity, and optimizing the configuration of the hybrid energy storage device. The optimized configuration of the energy storage device can be effectively realized by verifying the two methods.
