Single Phase Grid Connected PV with Active Filtering

Single Phase Grid connected PV, which works both as Grid tied inverter and active power filter.

A single-phase grid-tied photovoltaic system, which can operate, simultaneously, as shunt active power filter andinjecting active power into the grid. The photovoltaic system is composed of DC/DC step-up (boost)converter and full-bridgeDC-AC converter, performing both reactive power compensation and harmonic currentsuppression generated by nonlinear loads.Thealgorithm adopted to obtain the current reference of the DC-ACconverter is based on the synchronous reference frame (SRF)method.P & O MPPT algorithm is used to control theboost converter and extract maximum power from the PV array.
