In recent years, there has been a growing interest in renewable energy resources, which are becoming increasingly popular. With the increase of power generation using distributed energy resources (DER), there is a concern about the lack of inertia in the power system. Virtual synchronous generator (VSG)control is known to improve the stability of the grid by providing virtual inertia to the inverters that link DER to the grid. However, in the event of an accident, the inverter is required to instantaneously generate more power than its rated capacity. When power exceeding the rated power is generated, the inverter may be damaged, and operation cannot be continued. In this paper, the stability of the inverter was verified by setting a power limit above the rated power. As a result, it was found that although it was less than ideal VSG control, it was quicker to return to normal operation than conventional inverters.
