A Three-Phase Grid-Connected PV System Based on SAPF for Power Quality Improvement
Abstract: This paper proposes
a combined system of three-phase four-wire shunt active power filter (SAPF),
and photovoltaic generator (PVG), to solve the power quality problems such as
harmonic currents, poor power factor, and unbalanced load. In addition, the proposed
system can inject the issued energy from the PVG into the utility grid. To
increase the efficiency of the PVG and extract the maximum photovoltaic
(PV) power under variable atmospheric
conditions, a maximum power point tracking (MPPT) technique based on perturb
and observe (P&O) is implemented in the DC/DC boost converter. The
effectiveness of the proposed PVG-SAPF (PVG and SAPF) based on the use of
synchronous reference frame theory (SRF theory) under unbalanced nonlinear
load. The proposed PVG-SAPF is validated through numerical simulations using
Matlab/Simulink software. The simulation results show the effectiveness of the
proposed PVG-SAPF.
