Abstract: A smart grid integration system includes an AC grid and at least one power conversion apparatus. 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 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 operation signal transmitted from the control unit and calculates power information by multiplying the voltage operation signal and the current information signal.

Abstract: A smart switch system (20) includes a smart switch box (10). The smart switch box (10) includes a switch box output side (102), an output-side voltage detection unit (104), a switch control unit (106), a switch unit (108) and a switch box input side (110). The output-side voltage detection unit (104) detects a voltage of the switch box output side (102) and informs the switch control unit (106) of the voltage of the switch box output side (102). According to the voltage of the switch box output side (102), the switch control unit (106) turns on or off the switch unit (108). When the switch control unit (106) turns on the switch unit (108), an input voltage (112) sent from a direct-current voltage generation apparatus (50) is sent to the switch box output side (102) through the switch box input side (110) and the switch unit (108).
