Systems and methods for real-time detection and mitigation of power system oscillatory instability

A method for controlling a power system, the method performed by self-tuning computer system including at least one processor in communication with a power system stabilizer and at least one memory device, the method comprising:

• receiving a plurality of sensor information of operation of a generator;
• detecting an oscillation during operation of the generator from the plurality of sensor information;
• determining a gain and a time constant to counteract the oscillation;
• and
• transmitting, to the power system stabilizer, the gain and the time constant, wherein the power system stabilizer is configured to instruct an automatic voltage regulator to adjust its pulse output voltage based on the gain and the time constant.
