What is meant by 'System Restoration'?

'System Restoration' refers specifically to the process of returning the power system to normal operations after a disturbance. This involves a series of steps and protocols that are activated in the event of a disruption, such as a blackout or significant system failure, to ensure that power is restored safely, efficiently, and in a controlled manner.

In this context, the focus is on not just restoring power, but also ensuring that the system can be returned to stable, reliable operations. This might involve coordinating with various entities, assessing system conditions, and implementing recovery strategies to restore service methodically and prevent further issues.

The other choices, although related to the energy sector, do not accurately capture the essence of 'System Restoration.' Upgrading components or replacing technology might contribute to enhancing system reliability in the long term, but they do not directly relate to the immediate and critical response needed after a disturbance. Developing new energy sources is a proactive measure that is not specific to the restoration process.
