Abstract :
A simulation model of Maximum Power Point Tracking(MPPT)controller is developed using incremental conductance and a simulation model for photovoltaic array is developed based on the mathematical model of photovoltaic module under Power Systems CAD(PSCAD)environment. Then a single-phase grid-connected photovoltaic generation system has been built based on the method of current hysteresis control. The simulation result indicated that this system can realize the Maximum power point tracking rapidly when the intensity of solar radiation changes. Also the united power factor of grid-connected current can be obtained.
