System Restoration

Definition

System restoration refers to the processes and actions taken to bring a power system back to a stable state following a blackout or significant disturbance. This involves restoring power generation and distribution, ensuring the stability of the grid, and gradually re-energizing affected areas while managing load demands. The effectiveness of restoration efforts is critical in minimizing the consequences of blackouts, which can include economic losses and impacts on public safety.
