Abstract: | Integrating renewable sources into the weak distribution grid is challenging due to the distortions in the grid voltages and the load currents. This article implements a dual second-order generalized integrator frequency locked loop (DSOGI-FLL) and a robust modified Champernowne function-based adaptive filter (MCAF) based control scheme to enhance the power quality in a grid-connected photovoltaic system (GCPVS). The control scheme utilizes DSOGI-FLL to extract the fundamental positive sequence components (FPSC) from distorted grid voltages to further use in synchronization. The MCAF filters the distorted load currents to improve the grid power quality (PQ). The photovoltaic (PV) system is integrated into the weak grid while the grid PQ is within the limits defined by the IEEE-519-2022 standard. The behavior of GCPVS is analyzed at distorted grid voltages, load variation, and solar irradiance variation. The MATLAB simulation results are presented to understand the operation of GCPVS |
