This paper proposes to set up 100 KWp grid connected photovoltaic (PV) power plant. The maximum power point tracking (MPPT) of this PV power plant is controlled by using a proposed combination between the incremental conductance and integral regulator (CR) control and the fuzzy logic control (FLC). This combination is applied to the PV power plant through dc-dc boost converter. The proposed combination collects both advantages of CR and FLC control methods. Whereas the CR control method is simple and widely used for controlling MPPT of PV panels, the FLC provides accurate fast response, high performance and maximum efficiency. Therefore, the combination of these controllers together could improve the MPPT and the PV performance, especially with existing fluctuated solar irradiation and electrical noise. For comparative evaluation, the response of the PV plant with the application of the combined CR and FLC is compared to the responses of the application of each of them separately. The PV plant is simulated using MATLAB and Simulink.
