Abstract

This paper presents a method of integrating Active Power Filter (APF) in Photo Voltaic(PV) system. Distributed Generation (DG) concept is attracting the attention of power sector engineers throughout the world due to its technical, economical and environmental benefits. Among the various possibilities of DGs, photovoltaic (PV) systems have drawn prominent attention In spite of their high cost and poor conversion efficiency. Power quality issues such as harmonics, are inevitable in such distribution system which must be sorted out. Separate Passive/Active Filters can be used for this purpose. However single VSI Converter can be made used for processing and connecting PV energy to system as well as for power Quality improvement of the whole system. This reduces the complexity and cost of the system significantly. The proposed PV System with single converter acting as APF is not only able to track the maximum power point of the photovoltaic energy but also compensate harmonic currents from the grid line and correct the power factor. Peak detection method of control strategy is employed in APF for power quality improvement. P&O algorithm is used for achieving Maximum Power Point Tracking of the PV generator. The proposed system of APF embedded in PV system is simulated using MATLAB/SIMULINK and tested for power quality improvement under the maximum Power Point Tracking of PV generator.
