DG system is constructed by the solar photovoltaic array, and power electronic converter is applied to control the magnitude of injection power. This operation method of customer participate in equipped with DG to system load leveling can effectively relief the transmission congestion, and do not influence the system dynamic performance. Afterward increases a storage system ,the storage equipment is constructed by a battery, and connect to the DC side of the DG. When the energy of photovoltaic array is excessive, these excess energy is absorbed and stored by the battery. On the other hand, when the energy of the photovoltaic array is insufficient, battery provides the lack power to maintain the required supply. From the simulation results, the storage system may admit the system surplus energy and supplement system insufficient energy, enhances the system reliability and the energy utilization ratio.
