Evolutionary Prisoner´s Dilemma in updating fuzzy linguistic model to damp power system oscillations

This study presents a novel technique to extract and update the rules of fuzzy linguistic model (FLM). The interrelations between inputs and outputs of a FLM are assigned using payoff matrix through Prisoner´s Dilemma (PD). These interrelations are updated by updating the payoff matrix through Evolutionary Algorithm based PD to propose Evolutionary Algorithm based fuzzy Prisoner´s Dilemma linguistic model (FPDLM). The effect of evolutionary algorithm based FPDLM as power system stabiliser is tested on single machine infinite bus system and also multi machine system.
