Operation of PV System With dc-dc Boost-Fed Shunt Active Filter to Mitigate Current Harmonics and Energy Conservation

摘要

A three-phase four-wire shunt active filter (SAF) with photovoltaic (PV) array operated dc-dc converter is proposed in this paper. When the PV system generates excessive or equal power required to the load demand, then the coordinating logic disconnects the service grid from the load and reduces panel tariff. The PV array is connected to the dc side of SAF through the dc-dc converter with fuzzy-based perturb and observe (P&O) maximum power-point tracking (MPPT) algorithm to eliminate the drawback in the conventional PV system. The reference currents extracted by the fuzzy logic controller-based p-q control strategy. This proposed PV-SAF, if connected at the terminals of a small industry or a home, or a small, lighted institution, can avoid the use of an interruptible power supply and individual stabilizer. A MATLAB simulink is presented to validate the advantage of the proposed system.
