摘要：Demand in electricity makes the passion for renewable energy. The renewable energy can be effectively utilized when it is grid connected. In this paper Photo Voltaic (PV) power system is proposed for grid connected applications. Important factors to be considered in grid connection are quality of power, stability of the voltage and reliability. The quality and stability of voltage in a grid connected PV system can be improved by a STATCOM. Many researchers analyzed the performance of STATCOM with balanced grid voltage dips. Under unbalanced grid voltage dips, the negative sequence voltage causes poor power quality of power. In this paper, grid connected PV system with a STATCOM is proposed with balanced and unbalanced voltage sags and swells. The positive and the negative sequence voltage compensation by a STATCOM is proposed to improve the stability and quality of voltage. The entire system is analyzed by simulation using MATLAB/ Simulink.
