What is considered the ideal operating point for regulation?

The ideal operating point for regulation is the midpoint. At this point, the generation resources are able to respond effectively to fluctuations in demand. Operating around the midpoint allows for sufficient capacity to be ramped up or down as required to maintain system reliability. This is particularly important for balancing supply and demand in real-time, as it provides the flexibility needed to make adjustments.

When generation resources are at the midpoint operating point, they have a good amount of reserve capacity available without being stressed or overly taxed, which is critical for keeping the power system stable. This balance ensures that operators can manage small variances in load without needing to take drastic actions or cause undue stress on the generation units. Consequently, maintaining operation around the midpoint enhances overall system responsiveness, efficiency, and reliability in power delivery.
