POD Based FACTs Controller for Power Quality Enhancement in Wind Integrated System

In remote areas or in a region where the grid cannot provide supply the only solution is by generating power using renewable resources. Among renewable resources wind energy has its mark among other sources. The power generation by wind faces many challenges one among those is the fault. It is a critical parameter while considering power generation so there is a need of compensating devices like FACTS. Different types of FACTS devices are available they are shunt connected device and series connected device. STATCOM is well known among shunt connected facts devices and SSSC among series connected device. Combination of both shunt and series connected device is Unified Power Flow Controller (UPFC). By connecting these devices on the load side of Induction generators the problem during the fault that is the sag in voltage can be eliminated. A detailed study among these devices and their effect on the load side of induction generator are presented in this paper
