Application of Optimization Techniques to Mitigate Voltage Sag and Swell by Using Real Time Values

In this Research paper removal of faults associated in real life situation related to 11KV substations is investigated. The power system data is taken at different time periods under various fault conditions and voltage sag/swell both are mitigated from the real time data by using D-STATCOM. When Grey Wolf Optimization technique is associated with D-STATCOM, it has shown more efficient results for voltage sag/swell. Later, a FACT controller device called UPQC has been used to overcome the same problem of voltage fluctuation in distribution system. The results have shown that UPQC is more efficient in comparison to D-STATCOM and GWO as values obtained through MATLAB SIMULINK in case of UPQC are closer to normal values.
