What appropriate actions will Transmission Operators take to mitigate System Operating Limits (SOL) and maintain system reliability?

Transmission Operators are tasked with managing system reliability, particularly when dealing with System Operating Limits (SOL). In this context, changing the output of generators is a direct and effective way to mitigate SOL and maintain stability within the power system. By adjusting generator output, operators can better balance generation and load, ensuring that the system operates within its safe parameters.

Enhancing generation output can be utilized to meet demand during peak periods or to compensate for unexpected loads or generator outages. This proactive measure helps in avoiding congestion and keeps the system from exceeding its established operational limits.

While strategies like increasing load and generation interchange and enhancing communication with consumers are important for overall system planning and operation, the immediate action to directly influence SOL and provide a stable, reliable system rests with modifying generator outputs. Reducing system monitoring would be counterproductive as it can lead to lack of visibility and control over the system's performance, thus increasing risks to reliability.
