چکیده
The output power of photovoltaic (PV) module varies with module temperature, solar isolation and 1oad changes etc. In order to control the output power of single-phase gridconnected PV system according to the output power PV arrays, this paper presents a single-phase photovoltaic system that provides grid voltage support and Compensation of harmonic distortion at the point of common coupling (PCC) with fuzzy controller. The output power provided by the PV panels is controlled by a Maximum Power Point Tracking (MPPT) algorithm based on the incremental conductance method specifically modified to control the phase of the PV inverter voltage. A control circuit is developed and the performance of the control circuit is investigated in MATLAB-SIMULINK. The Matlab simulation results show that, the proposed method has good performance.
