Control Method of Stand-alone Microgrid using Inverter for ESS

The present invention relates to a plurality of control method of the energy saving stand-alone micro-grid using the apparatus inverter, and more particularly, using a plurality of energy storage devices in a stand-alone micro-grid is stable with a minimum of operation of the diesel generator reliability is high It relates to a method of controlling a stand-alone micro-grid using a plurality of inverters for the energy storage device for maintaining the electric power system. The present invention provides a method of controlling a stand-alone micro-grid using a number of diesel generator and a plurality of inverters for the energy storage device, a first step of identifying the operating state of the diesel generator, in dependence on the operating state of the energy storage and a second step of controlling the operating mode of the for unit inverter, wherein each inverter in the second stage depending on the occurrence of a signal input from the other inverter through the digital controller of the internal self-control with the operating modes provides a number of energy saving control method of a stand-alone micro-grid using the device for the inverter, characterized in that a.
