What aspect is essential for the restoration of the transmission system?

The synchronization of generation is crucial for the restoration of the transmission system because it ensures that all generating units operate in unison, maintaining stability and allowing for the smooth integration of power into the grid. When a transmission system experiences a fault or outage, restoring power requires that the generating units be aligned in terms of frequency and phase. This synchronization prevents issues such as voltage fluctuations and potential damage to equipment as power is restored.

If generation units are unsynchronized, it can lead to instability and oscillations within the system, making it challenging to supply power reliably. Therefore, achieving synchronization is a fundamental step in the restoration process, facilitating a smooth and coordinated return to normal operations. This aspect overarches the importance of resources and load management, as even with sufficient resources and effective management strategies, without synchronization, the transmission system cannot be restored effectively.
