Confronting to Non-linear Events and Enhancing the System on the Basis of PV-UPFC

Electric power systems are exposed to various types of Power Quality (PQ) disturbances. A PQ assessment is necessary to maintain the accurate operation of electrical sensitive equipment and to ensure its maintenance. Therefore, there will be a need to investigate and mitigate PQ events. In our modern times, we have noticed that AC distribution systems suffer from very consistent pollution to use a lot of loads as these loads generate harmonics that reduce the power quality of the system. The main objective of this paper is to conserve PQ through Flexible Alternating Current Transmission Systems (FACTS) such as Unified Power Flow Controller (UPFC) using Photovoltaic (PV) arrays. In addition, the system is designed during a generator source with a wind power generator where the results are compared before and after the control on each bus with the display of harmonics of current and voltage. Finally, the results presented in this paper indicate the ability of the UPFC to control the event and inflation and reduce the harmonics.
