    Abstract: This paper proposed a new approach to design the power system stablizers (PSS) by utilizing the fuzzy theory, genetic algorithms and grey system theory. The design of a PSS can be formulated as an optimal linear regulator control problem; however, implementing this technique requires the design of estimators. This increases the implementation and reduces the reliability of the control system. Therefore, a favor control scheme that uses only some desired state variables; such as torque angle and speed will be used. To deal with this problem, we use the optimal reduced models to reduce the power system model into two state variables system for each generator and use the variable structure dynamic grey prediction controller to find the control signal of each generator. The grey predictor is adopted to make the next-step prediction for the output states of the power system, the fuzzy system is built to produce an appropriate forecasting step and the GA is used to choose the appropriate parameters of the fuzzy system. Finally, the advantages of the proposed method are illustrated by numerical simulation of the two machines-infinite-bus power systems.
