Harmonics Reduction in Grid-Integrated Photovoltaic Cell and Wind Generator System Using Type-2 Fuzzy Voltage Source Converter (VSC) Control

The integration of sustainable energy sources, including photovoltaic (PV) cells and wind generators, into the electrical grid presents certain hurdles, including the production of harmonics that have the potential to deteriorate power quality. This work investigates how to reduce these harmonics in a grid-integrated PV and wind generating system by using a Type-2 Fuzzy Voltage Source Converter (VSC) control approach. In contrast to conventional PI controllers, the Type-2 fuzzy logic controller takes uncertainty into account and offers a more reliable performance in changing circumstances. The effectiveness of the suggested system is assessed in various scenarios, such as shifting wind speeds for wind turbines and fluctuating irradiation levels for PV cells. According to simulation results, the system's total harmonic distortion (THD) is much decreased by the Type-2 Fuzzy VSC management, allowing for a more seamless integration of renewable energy sources into the grid. Furthermore, the power system's dynamic response and stability are improved by the suggested control approach. According to the research, using Type-2 Fuzzy VSC management in hybrid renewable energy systems is a viable way to enhance power quality and dependability, which will promote the development of a more sustainable and effective energy infrastructure.
