Description
Summary:Thid paper deals with the improvement of the quality of the grid current which is affected by nonlinear load supplied by single-phase photovoltaic system connected to the grid. Thus, different perturbations are introduced by nonlinear load such as harmonic distortion and power factor deterioration, which lead to the degradation of the quality of the current of the PV system. To eliminate these disturbances, this work consists on the use of the inverter connected to the grid as a shunt active power filter. Therefore, based on an effective control method of the PV inverter which uses an original algorithm useful to determine the disturbing current, the quality of the grid current is strongly improved by cancelling the different disturbances injected by the nonlinear load. The effectiveness of the suggested algorithm to improve the quality of the current is verified by simulation and validated experimentally through an experimental platform.
