What must a Reliability Coordinator ensure before Synchronizing systems?

The requirement for a Reliability Coordinator to ensure that system load and generation are balanced on both sides, along with closely matching voltage and frequency, is fundamental for safe and reliable synchronization of electrical systems.

When synchronizing systems, it is critical that the generation output matches the load demand to prevent imbalances that could lead to instability or outages. If the generation on one side does not equate to the load demand on the other, it can result in power fluctuations that jeopardize system integrity.

In addition, voltage and frequency matching are vital for synchronization. The voltage must be approximately equal so that when the systems connect, there is no sudden voltage surge that can cause equipment damage or malfunction. Similarly, frequency must be closely aligned because different frequencies can lead to rotor movement in generators, which could cause severe mechanical issues or power quality problems.

While options mentioning requirements such as phase angle or generation specifics may touch on certain aspects of synchronization, they don't encompass the broader and equally important criteria of load balance and the close matching of voltage and frequency, which are central to the correct answer provided.
