Power Quality Enhancement through Reactive Power Compensation Using Hybrid STATCOM

The power quality issues is the major concerned because of increase in power demand as well as integration of various distributed generation system in to the grid. This result in to the increase in voltage instability, power flow fluctuations, voltage flickers, voltage sag/swell and harmonics in the power system. This paper is based on a shunt FACTS device used to improve the voltage profile by compensating reactive power with Thyristor based LC filter in conjunction with low DC link voltage VSC based Inverter. Modelling and design of the said topology is presented in the paper. Also MATLAB simulation design with various type of load conditions are provided in the paper.
