Abstract : The stability of the power systems is of major concern when the produced power undergoes various deterioration due to various factors. The feedback systems like PID controller are used with coordinated controllers in order to maintain the stability by improving the gain of the system when it is affected. In the same way, the Power Stability Systems are used to maintain the equilibrium of the power system. Irrespective of the usage of PID controllers and PSS, there is the presence of stability issues in the system. Biogeography based Optimization is an eonian approach that works in the assumption less environment. Therefore, this paper proposes the usage of BBO algorithm in the stability enhancement to vary the excitation level based on the error occurred. In order to reduce the computation complexity, improved BBO algorithm is used to select the appropriate stability parameter values to excite the coordinated controller.
