Abstract

As a preliminary analysis, this paper presents the design of Bryson, Boudarel and Multistage-based Linear Quadratic Regulator (LQR) optimal controllers for the power system with Uniform Power Flow Controller (UPFC) at light, normal and heavy load conditions. For each load condition, the two best optimized feedback controllers are selected which is based on the preliminary analysis, and optimal switching strategy was implemented between two candidate controllers to optimize the output energy. The proposed solution is tested by using linearized Single Machine Infinite Bus (SMIB) Phillips-Heffron power system model installed with Uniform Power Flow Controller (UPFC). Simulation was done to verify the hypothesis using MATLAB/SIMULINK platform./p>
