State-Feedback Control for Damping Inter-area Oscillations on Electrical Power Systems

In this work a state-feedback controller for pole placement is presented. In addition, a model predictive control (MPC) to minimize the magnitude of the controller input is also presented. The MPC use an observer to estimate the states of the plant and optimize a cost function to maintain the input within a pre-defined limit. The proposed approach is validate trough nonlinear simulations using the equivalent Nordic power system and where a Static Var Compensator is used as actuator. Wide-area signals from Phasor Measurement Units (PMUs) are used to improve the damping of the system.
