Large-scale PV power generation connected to the grid is causing a number of problems, such as voltage stability, reactive power adjustment, operational dependability, and more. In order to offer reactive power adjustment and boost the controllability of PV systems, new switching devices and improved control techniques of FACTS devices like STATCOM are deployed. Proposed control techniques include Proportional-Integral (PI) and Fuzzy-PI controllers (FL-PI), as well as their optimization using newly created Hybrid Chi-Mo optimization. The benefit of Hybrid Chi-Mo optimization is that it can solve high-dimensional problems while reducing two fundamental issues, such as sluggish convergence speed and local optimal trapping. Comparing the PI controller to the optimized FL-PI controller, the simulation results have been enhanced.
