Solar PV Generation system Interfaced to3- �� Grid with Compensation

This book is focused on the improvement of the current quality at the Point of Common Coupling (PCC) of a three-phase grid connected photovoltaic system supplying unbalanced and nonlinear loads.To improve the grid current quality at the PCC the PV inverter is performed as a shunt active power filter in addition to its main task which is the injection of the PV generated power. Thus this book proposes a novel and efficient algorithm based on the symmetrical component methodology and the FFT to extract the positive sequence current which represents the balanced fundamental load current.
