Abstract

Certain exemplary embodiments provide a method comprising: detecting a NERC disturbance in an electrical power system; determining a first corrective action to return the electrical power system to a pre-disturbance level within a predetermined disturbance recovery time; determining a second corrective action to cause the electrical power system to meet one or more predefined NERC CPS compliance target values; and providing a corrective control signal to the electrical power system.

Claims

1. A method, comprising:

detecting a NERC disturbance in an electrical power system;
