A Review on the Use of Active Power Filter for Grid-Connected Renewable Energy Conversion Systems

Renewable energy sources such as photovoltaic (PV) and wind energies are integrated into the grid due to their low global emissions higher power conversion efficiency techniques. Grid-connected inverters core components of distributed generation networks. However, several harmonic current voltage variations affect performance circuits in grid-connected These issues can be easily resolved using passive filters, static vector generators, dynamic filters (APFs). In higher-level units, cost, dimensions, weight increase proportionally. The purpose this research is evaluate advanced APFs for reducing switches weight, scale. Several studied APF inverter topologies, including single-phase, three-phase AC–AC, back-to-back, common parameters, have been considered. Cost-effective solutions PV-based transformers based on APF, fewer inverters, multiple multifunctional wind-assisted systems studied.
