Abstract

The point of common coupling (PCC) voltage fluctuation and waveform distortion will arise due to high penetration of distributed PV system connected to the distribution network. This paper analyzes the principle of voltage fluctuation and distortion in the PCC, points out shortcomings of the existing regulation methods, and proposes the voltage quality regulation technology that is based on the dual second-order generalized integration phase-locked loop with a pre-filter (DSOGI-WPF-PLL), realizes the voltage phase locked and the fundamental frequency positive sequence voltage component detected very accurately, meanwhile extracts the harmonic voltage components. In order to suppress PCC voltage fluctuation and distortion, the comprehensive controller with proportional integral control and repetitive control is used to achieve good tracking of the reference current. The MATLAB/Simulink simulation results demonstrate the effectiveness of the proposed control technique.
