Abstract
This research proposes the control power filtering single-phase grid-connected photovoltaic system using a single stage converter with active and reactive power filter functionality (ARPFF). The proposed system offers multi-functionality, namely the excessive power transfer from the nonlinear load on the grid, simultaneously acting as an active power filter to compensate for reactive power and to mitigate harmonics of the grid current resulting in nearly unity grid power factor, the capability of reactive power control and maximum power point tracking of the photovoltaic modules. The implemented system tested under various conditions such as power transfer with different current command throughout maximum power point transfer at different insolation, a step change in nonlinear load level, and reactive power control supplied to the grid. The experimental results are in accordance showing the correctness of the proposed technique.
