What is the action taken after a manual load dump is issued?

When a manual load dump is issued, it typically results in an "All Call" action. This refers to a systematic process in which a signal is sent out to all relevant areas of the grid to either shed load or confirm system stability. The "All Call" action is critical for managing grid reliability, especially following incidents that may have caused significant voltage or frequency disturbances.

By executing an "All Call," operators can ensure that all generators and load resources are synchronized and prepared for recovery from the disturbance, thereby maximizing the overall stability and efficiency of the power system. This coordination helps prevent cascading failures and reassures that all parts of the grid are aligned for a successful load recovery process.

In contrast, actions like "Partial Reset," "Load Recovery," and "System Check" each play distinct roles within system operations, but they do not correspond directly to the immediate and broad-based response necessary following a manual load dump.
