Under emergency situations the system security is the most important concern. The main preoccupation of dispatcher in such critical situation is to assure service continuity and to keep the index power quality (voltage and frequency) in the secure limits. Relieving overloads and voltage violations caused by system contingencies, has great economic advantage compared to other control strategies, such as generation rescheduling, and load shedding. The coordination of control performances of multi type FACTS devices is very important issue, for the future power system planning and operation. In this paper, an approach based in flexible strategy is presented to find the optimal parameters setting of multi unified power flow controller (UPFC) devices to relieve overloads and voltage violation based in practical experience rules from fuzzy logic concept. The approach proposed is implemented with Matlab and tested to IEEE-30 Bus system and to the England test system 39 buses.
