Design and performance of dynamic voltage restorer using genetic algorithm

In the present scenario, sensitive loads suffer nearly 80% of power quality problems especially due to voltage sag. Dynamic voltage restorer (DVR) finds its perfect application as a compensator to mitigate the voltage sag problem. In this paper, source voltage suffers voltage sag of 30% and load ter...

Description
Summary:In the present scenario, sensitive loads suffer nearly 80% of power quality problems especially due to voltage sag. Dynamic voltage restorer (DVR) finds its perfect application as a compensator to mitigate the voltage sag problem. In this paper, source voltage suffers voltage sag of 30% and load terminal voltage is regulated using proportional and integral (PI) controllers. Synchronous reference frame algorithm is adopted to generate reference load voltage for voltage source converter switching. Optimised values of the gains of PI controllers are achieved using genetic algorithm. Control strategy of the DVR is simulated using MATLAB software and performance of DVR is studied.
