PV/WT Integrated System Using the Gray Wolf Optimization Technique for Power Quality Improvement

This paper presents the integration of renewable energy sources such as photovoltaics, wind, and batteries to grid. The hybrid shunt active power filter (HSHAPF) is optimized with Gray wolf optimization (GWO) fractional order proportional integral controller (FOPI) for harmonic reduction under nonlinear unbalanced load conditions. With use GWO, parameters FOPI are tuned, which effectively minimizes harmonics. proposed model has compensated total distortions when compared without passive filter, a PI controller, GWO-FOPI-based controller. performance tested better tuned GWO technique. comparative results reflect best HSHAPF. suggested built in MATLAB/Simulink Platform.
