NOVEL OPERATION OF PV SYSTEM INTERFACED SHUNT ACTIVE FILTER FOR POWER QUALITY IMPROVEMENT

摘要

This paper presents an optimal operation of Photo-voltaic (PV) system based Shunt Active Filter (PV-SAF) for harmonic mitigation and reactive power compensation. When the PV system generates excessive or equal power required to the load demand, the coordinating logic disconnects the service grid from the load, reducing the panel tariff and global warming gasses. The PV module is connected to the DC side of SAF through the DC-DC converter with a fuzzy based Perturb & Observe (P&O) Maximum Power Point Tracking (MPPT) algorithm to eliminate the drawback of the conventional PV system. The reference currents extract by the Fuzzy logic controller is based on a PQ control strategy. This proposed PV-SAF, if connected at the terminals of a small industry or a home or a small enlightening 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.
