A 3-PLAYER ITERATIVE GAME TO DESIGN POWER SYSTEM STABILIZER THAT ENHANCES SMALL SIGNAL STABILITY

This paper presents an approach to damp power system oscillations and to improve small signal stability . Power System Stabilizer must be capable of providing adequate stabilizing signals over a wide range of disturbances and operating conditions. Hence, it is very important to appropriately tune the parameters of the power system stabilizer. Present work is to analyze the small signal stability of a multi machine test system. To reduce the complexity in analysis, optimal locations of proposed PSS are found by obtaining participation factor of respective modes. The paper proposes a systematic approach to tune the parameters of PSS by defining the interrelations between inputs and output, i.e., payoff matrix in the iterative prisoner’s dilemma.
