The microgrid composed of new power generations has been studied recently. The microgrid without utility power system will be examined in the future. We assume the isolated microgrid consists of a synchronous generator and an inverter power source. In this paper the stable operation of the microgrid without utility power system is studied in viewpoint of how larger capacity of the inverter power source compared to the capacity of the synchronous generator can be connected. Moreover, effects on stable operation by different inverter controls are discussed. Result of simulation shows that the capacity of the inverter less than or equal to five times of the generator gives stable operation. And the simulation result shows the application of the voltage control to the inverter will contribute stable operation of the power system.
