A transmission line is overloaded by 100 MWs. Which dispatch scenario provides adequate relief for the line?

In this scenario, the transmission line experiencing an overload of 100 MW requires a dispatch strategy that alleviates the excess load while maintaining system reliability. Increasing the Greenwood generator output by 200 MW provides adequate relief for the line because it effectively allows for an additional 100 MW to be redirected from the overloaded line to the generator. This results in relieving the overload while also allowing some additional support to the system, which can help manage peak demands or other unexpected conditions.

This adjustment to the Greenwood generator not only addresses the immediate issue of the overload by providing additional generation but also ensures that there is a buffer that could be essential in maintaining system stability and reliability. The flexibility of increasing generation at Greenwood means that it can help mitigate the risk of further overload situations or cascading failures in the grid.

The options of merely reducing the load on the line or increasing the Harbor generator also imply changes in system operations, but do not provide the same level of system support and excess generation capacity that an increase at the Greenwood generator would offer, especially since reducing load may not be feasible in all cases. Disconnecting the overloaded line, while a possible immediate action, does not address the generation side and could lead to supply issues elsewhere in the system. Therefore, increasing the Greenwood generator
