Abstract

The purpose of this investigation is to design a nonlinear controller that can be used in maintaining the bus voltages of power systems at desired values. The proposed controller is used for maintaining the bus voltages at desired values in response to faults or contingencies that occur in the transmission system. This study shows that the proposed nonlinear controller when used in conjunction with the shunt synchronous voltage sources can control the bus voltages to their desired values. The nonlinear controller is based on feedback linearization control (FBL) of nonlinear control theory
