Reactive power and voltage harmonics compensation applied of a shunt power active filter

This paper proposes a particular shunt power active filter including a conventional three-leg voltage source-inverter connected to the point of common coupling (PCC) between the distribution network and the load. The paper describes the structure of the power filter and then it gives a detailed explanation of the adopted strategy to control the reactive and active power flows and to compensate the voltage harmonics. Simulation results are presented to verify the performance of the proposed power active filter
