Abstract:
The present invention relates to an inverter device for a microgrid, and a method for controlling the same, the inverter device including: a waveform detector detecting a voltage waveform and a current waveform applied to a load; a control unit determining whether a sine wave appears based on the detected voltage waveform and the detected current waveform and performing voltage control or low order harmonic compensation depending on a determination result; and a switch generating a voltage waveform in a form of the sine wave by being turned on/off depending on a control signal received from the control unit and supplying the generated voltage waveform in the form of the sine wave to the load.

Claim (Index 2):
The inverter device of  claim 1 , wherein the control unit comprises:\n a load type determination unit determining that a type of the load is a fundamental wave when determining the sine wave appears in the detected voltage waveform and the detected current waveform, and determining that the type of the load is one of an unbalanced load and a non-linear load when determining the sine wave does not appear; a proportional-resonant controller controlling a voltage when being determined as the fundamental wave; and a resonant controller compensating for a low order harmonic when being determined as the unbalanced load and the non-linear load.
