Systems and methods for power system stabilization and oscillation damping control

A method comprising:

• receiving, at a computing device, frequency data associated with a power system;
• calculating, by the computing device, an estimate of a speed of a center of inertia signal for the power system, based at least on the received frequency data;
• calculating, by a controller, a control error signal for the power system based at least on a difference between a rotor speed and the estimate of the speed of the center of inertia signal;
• calculating, by the controller, an auxiliary input signal based at least on the control error signal;
• and
• receiving, by an actuator, the auxiliary input signal and provide an output configured to improve a stability of the power system.

A non-transitory computer readable medium having executable computer-executable instructions stored thereon that, if executed by one or more processors of a computer device, cause the computing device to perform one or more steps comprising:

• receiving frequency data from a plurality of sensors within a power system;
• calculating an estimate of a speed of a center of inertia signal for the power system, based at least on the received frequency data;
• calculating a control error signal for the power system based at least on a difference between a rotor speed and the estimate of the speed of the center of inertia signal;
• calculating an auxiliary input signal based at least on the control error signal;
• and
• receiving the auxiliary input signal and providing an output configured to improve a stability of the power system.
