Abstract: Renewable energy power system connected to the grid reduces the gap between source and demand and also limits the carbon emission. When SPV system integrated with the grid, the main grid issues are power quality, voltage stability and reliability. The voltage dips, unbalanced voltage and negative sequence voltage creating power quality issues with the grid. Many research works are under development to get balanced grid voltage. By the introduction of STATCOM in grid-connected systems, this can be achieved. In this study, grid integrated SPV system analyzed for both the unbalanced and voltage fluctuation and fuzzy gain scheduling controller is proposed for voltage compensation in STATCOM to enhance voltage stability. The total system is examined by simulation using MATLAB/Simulink.
