During the initial system restoration process, load pick-ups are recommended to be limited to what percentage of total synchronized generation?

The recommendation to limit load pick-ups to 5% of the total synchronized generation during the initial system restoration process is grounded in ensuring system stability and reliability. When a power system is being restored after an outage, it is crucial to maintain a delicate balance between generation and load.

By capping load pick-ups at 5%, the system minimizes the risk of overloading generators and associated equipment that may not yet be fully operational or at peak efficiency. This conservative approach helps prevent potential cascading failures that could occur if loads were increased too quickly, allowing operators to gradually bring systems online and verify that they are functioning correctly.

Additionally, this percentage provides a safety margin allowing for unforeseen fluctuations in generation or load dynamics during the restoration process. It serves to ensure that the grid can adequately respond to changes and maintain stability as more loads are added in successive steps.

In summary, maintaining a limit of 5% during initial load pick-up is a sound practice that prioritizes safety, reliability, and stability as systems are brought back online.
