In order to simulate and predict the behaviors of the real photovoltaic system, this paper develops a grid-connected photovoltaic simulation system with maximum power point tracking (MPPT) function using MATLAB software. An engineering model for the photovoltaic (PV) cell is first established and then combined with the models of an MPPT controller and a DC-DC converter. This paper uses an improved algorithm in the MPPT controller by comparing with the commonly-used algorithms. A DC-AC inverter using double closed loop control method is used to track the grid characteristics. The simulation results show that the system not only achieves the maximum power point tracking function quickly but also modulates the outputs of the inverter into sine waveforms accompanied with fewer ripples. And the power factor is close to 1.
