Performance Evaluation of a PV Inverter with Active Filter Functionalities

This paper presents the analysis of the operational performance of a PV inverter with added active filter (AF) functionalities. The paper details modelling of a PV inverter acting as an AF and performing compensation of fundamental reactive power and non-fundamental distortion power, i.e. compensation of harmonic emission due to nonlinear loads connected in the local network. Several load cases are analysed, including emission by constant harmonic current sources and full-wave rectifier loads, which are also considered for different operating powers.
