Integrating Hybrid Energy Storage System for Power Quality Enhancement of Grid Integrated Large Scale Wind Energy System

The global trend of incorporating renewable energy sources (RES) into conventional power grids is driven by environmental regulations, increasing electricity demand, and the regionalization of electricity generation. However, RES’s intermittent and unpredictable nature presents challenges for their integration into power systems, such as power quality, active and reactive power management, low-voltage ride-through capability, and protection issues. This paper examines the effects of large-scale wind energy systems on power quality parameters in traditional distribution systems, using a modified IEEE 33-node radial distribution test system as a basis. The study considered voltage profile, voltage and power fluctuations, and harmonics. A battery-supercapacitor hybrid energy storage system (HESS) is proposed to enhance power quality parameters, along with a power management algorithm for improved system performance. The proposed approach was validated through a simulation analysis conducted using MATLAB/Simulink software, demonstrating its effectiveness in addressing the challenges associated with integrating large-scale wind energy systems into power networks.
