GWO Optimized DC Link Voltage Control for DSTATCOM Power Module in Power Quality Issues Mitigation

The complications related with power quality like swell and sags are presented in this paper. A compensation method of D-STATCOM, which is an electronic device of conventional power is discussed. Moreover, the development and usage of D-STATCOM for swells, voltage sags and the complete outputs are also discussed. The results of simulation proved that the insertion of DSTATCOM reduces the sags in voltage which were caused because of the faults & swell on account of instant load switching in the distribution system. By using Sinusoidal Pulse Width Modulation (SPWM), Voltage Source Convert (VSC) was developed. The control method was found highly robust under the examination of large range of operating conditions in all cases. In D-STATCOM, advanced graphic equipment of MATLAB/SIMULINK is utilized for modelling and simulation. The DC link voltage is controlled through Grey Wolf Optimization algorithm.
