The power conversion apparatus includes a control unit and a communication unit. The control unit is coupled to the communication unit and receives a voltage signal 5 corresponding to a voltage of the AC grid. The control unit decomposes the voltage signal into a plurality of frequency components and sets a fundamental component and a plurality of dominant harmonic components as a voltage operation signal. The communication unit receives a current signal corresponding to a current flowing through a circuit node through a current port and generates a current information signal. The communication unit receives the voltage 10 operation signal transmitted from the control unit and calculates power information by multiplying the voltage operation signal and the current information signal.
