<p>Provided is an apparatus for controlling reactive power injection of a grid connected inverter. The apparatus includes: a reactive power command calculating unit configured to calculate a relative value of a reactive power command or an absolute value of the reactive power command by corresponding to a plurality of wireless power injection methods to output the value; and an effective power/reactive power command level adjusting unit which receives a reactive power injection method selection signal, and performs adjusting the level of one reactive power command selected from the relative value of the wireless power command and the absolute value of the reactive power command within a rated current range of the inverter, and the level of the inputted effective power command within the rated current range of the inverter to output each result.</p> |
