This paper presents, investigation on PQ based problems using DVR. Dynamic Voltage Restorer (DVR) is a series connected flexible AC Transmission System controller used to compensate PQ problems like voltage swells and sags. A DVR used to compensate deep PQ problems and harmonics. The control of DVR has been proposed by using dqo based Pseudo-inverse and Magnitude Conversions transformation for mitigation of PQ problems in power systems. The proposed article explains the load flow dqo transformation algorithm working for mitigation of PQ problems and used for increase power quality in efficient. The control of DVR was achieved by using proposed algorithm. Here the device used to the load with negligible effect on PQ compensation capability. The high oriented graphical representations are facilitates and topology was modeled, simulated using MAT Lab/Sim power systems.
