Voltage Control in Power Grids With High Renewable Penetration

As the integration of renewable energy sources (RES) such as solar photovoltaics (PV) and wind power increases, voltage control in power systems has become a critical challenge. Traditional voltage control methods struggle to accommodate the variability and intermittency of these energy sources, leading to potential power quality issues and system instability. This thesis explores the role of PV smart inverters in voltage control strategies to enhance grid stability and minimize voltage fluctuations in high-RES penetration power systems. By implementing and simulating advanced voltage control techniques using MATLAB and MATPOWER, this study evaluates the effectiveness of photovoltaic solutions in maintaining the reliability of the power system. The results indicate the potential for PV-based control methods to improve grid stability; however, more sophisticated methods will be required for real-world scale solutions.
