PID-MPC Based Automatic Voltage Regulator Design in Wide-Area Interconnect Power System

The objective of this study is to deal with the problem of robust tuning of automatic voltage regulator (AVR) in multi-machine power system. This paper investigates the Model predictive control (MPC) strategy, analyses and compares the control effects with ProportionalIntegral-Derivative (PID) control strategy. The proposed PIDMPC method improved the stability of the power system with multiple generators. The result shows that it can provide better damping of power system oscillations under small and large disturbances even with the inclusion of local power system stabilizers (PSSs). The effectiveness of the proposed approach is demonstrated through a two areas, four machines power system. The proposed algorithm carried out using MATLAB/SIMULINK software package. Keywords—Automatic Voltage Regulator, PID controller, MPC, multi-area power systems, multiband power system stabilizer.
