Microgrids are becoming increasingly attractive to consumers as it allows utilization of easily available renewable energy sources. They are usually installed at consumer’s sites i.e the distribution end. Due to high saturation of distributed generation units with different types of loads, microgrids can cause power quality issues. Some of them are voltage swells and sags, and low power factor which further require reactive power compensation. This paper presents the utilization of the custom power device specifically STATCOM in mitigating the problem of voltage sags occurring in microgrid. The performance of STATCOM, installed in microgrid, is analyzed for reactive power compensation to overcome these concerned issues. The design of a neural network controller using voltage as feedback for significantly improving the dynamic performance of converter. The performance is analyzed with the help of neural network controller and the simulation studies have demonstrated the effective influence of the STATCOM on the improvement of the voltage using MATLAB/Simulink.
