What is a Remedial Action Scheme (RAS) designed to do?

A Remedial Action Scheme (RAS) is specifically designed to detect abnormal system conditions within an electrical grid or power system. When such conditions are identified, the RAS can initiate predetermined actions to stabilize the system and prevent further issues, such as overloads or cascading failures.

The primary function of a RAS is to continuously monitor various parameters of the electrical system. If it detects anomalies—such as voltage fluctuations, frequency deviations, or unexpected changes in load—it can automatically take corrective actions. These actions might include disconnecting certain loads, reconfiguring system components, or even adjusting generation levels, all aimed at maintaining stability and reliability within the grid.

In the context of other options, increasing generation may be a response to a detected condition but is not the core purpose of a RAS. Controlling load dispatching is related but falls more under operational procedures rather than the detection and automatic response aspects of RAS. Notifying users, while important for communication, does not encapsulate the fundamental role of a RAS, which is more focused on the immediate detection and response to system abnormalities to ensure grid integrity.
