Abstract: Provided is a system and method for detecting source(s) of oscillation on a power grid. In one example, the method may include receiving measurements from one or more sensors on a power grid, the measurements including data of an oscillation within the power grid, determining, via execution of one or more machine learning model, a candidate set of power system components disposed on the power grid that are candidates for being the source(s) of the oscillation, identifying, via execution of an optimization model, a component from among the candidate set of power system components which is the source (e.g., location, controller type, and/or asset type) of the oscillation, and displaying, via a user interface, information about the identified component.

Abstract: Briefly, embodiments are directed to a system, method, and article for generating a power system load model of a power system. Power grid disturbance data may be accessed. A power system simulation engine may be prepared, wherein the simulation engine may implement the power system model of the power system. A parameter subset A may be identified from a knowledge-based approach. The parameter subset B may be identified based on a special grid event type based on the power grid disturbance data. A final parameter subset may be selectively determined based on parameter subsets A and B using a decision-making approach. At least one parameter of the final parameter subset may be tuned. One or more parameters of the power system load model may be modified based on the tuning.
