Power system disturbance localization using recurrence quantification analysis and minimum-volume-enclosing ellipsoid

A system, comprising:

• a power system;
• a plurality of sensors distributed across the power system;
• and
• a computer system including one or more processors, one or more display units, and memory storing instructions adapted to be executed by the plurality of processors to perform operations comprising:
• receiving data from the plurality of sensors;
• identifying, based on the data and from the plurality of sensors, a number of sensors that are closest to a disturbance in the power system;
• constructing a plurality of minimum-volume-enclosing ellipsoids based on and enclosing the data received from the identified sensors;
• extracting one or more parameters from the plurality of ellipsoids;
• inputting the one or more parameters into a regression algorithm to determine the location of the disturbance;
• and
• modifying an operation of at least one element in the power system to mitigate an impact of the disturbance on the power system based on the determined location of the disturbance.

A computer program product, comprising:

• a tangible computer readable storage medium comprising computer readable program code embodied in the medium that when executed by a processor causes the processor to perform operations comprising:
• receiving data from a plurality of sensors distributed across the power system;
• identifying, based on the data from the plurality of sensors, a number of sensors that are closest to the disturbance;
• constructing a plurality of minimum-volume-enclosing ellipsoids based on and enclosing the data received from the identified sensors;
• extracting one or more parameters from the plurality of ellipsoids;
• inputting the one or more parameters into a regression algorithm to determine the location of the disturbance;
• and
• modifying an operation of at least one element in the power system to mitigate an impact of the disturbance on the power system based on the determined location of the disturbance.
