A suitable method for the user to control operation of the network side from microgrids

The present invention discloses a method for operation control from a user-side network suitable for microgrid. Micro grid for off-grid mode of operation of the present invention studied, using a layered structure microgrid coordinated control strategy, the layered structure comprising a local control layer and a centralized control layer, for a variety of load and operating conditions of the multi-power coordinated control between. In the present invention, the premise of ensuring power quality, full use of the advantages of each micro power supply, efficiently and reliably on the user side microgrid many types of micro-power cooperative control, to meet the energy Ping Heng microgrid and output requirements. The method is simple and practical, the internal micro-grid voltage, frequency stability, to protect the important load safe operation, taking full advantage of the photovoltaic power generation system output to improve the utilization of renewable energy.
