Modeling and simuling power active filter using method of generalized reactive power theory

The paper present the structure of an active parallel filter for distorting regime and reactive power compensation. The active power filter control is based on generalized reactive power theory. The authors present the modeling of parallel active filter based on this theory and the simulation results in MATLAB-SIMULINK for two methods of power filter regulator. One of this is based on instantaneous reactive power (TGPI_Q) and the other is based on instantaneous active power (TGPI_P).
