What results from Net Scheduled Interchange being greater than Net Actual Interchange?

When Net Scheduled Interchange surpasses Net Actual Interchange, it indicates that there is more power scheduled to be delivered to a specific area than what is actually being provided. This discrepancy leads to inadvertent generation. Inadvertent generation occurs because the system must compensate for this shortfall in actual generation to balance the supply with the demand. This often results in unwanted generation from power plants that were not scheduled to run, creating an imbalance that can affect grid stability.

In the context of the electric power sector, managing the balance between scheduled and actual interchange is critical to maintaining the integrity of the power grid. The difference can arise due to various factors, such as unexpected outages or changes in demand, but the result is that in order to meet the demand, the grid may automatically draw on surplus generation resources, which is categorized as inadvertent generation.

The other options do not address this specific condition of scheduled versus actual interchange as appropriately as inadvertent generation does. While frequency deviation can arise from such imbalances, it is a broader consequence of overall system instability rather than a direct result of the imbalance itself. Similarly, excess demand and regulatory penalties are also potential issues in the power system, but they do not directly stem from the relationship between Net Scheduled and Net
