In a load rejection scheme, what does the term 'load' refer to?

In a load rejection scheme, the term "load" predominantly refers to the generator MW output. This denotes the real-time electrical demand that is being met by the generator at any given moment. When a load rejection occurs, such as when a significant portion of the load suddenly disconnects, the generator must respond appropriately. This situation can lead to an imbalance between the generator's output and the remaining load, potentially causing frequency fluctuations or instability within the power system.

The generator's output is critical because load rejection scenarios require automatic or manual mechanisms to either reduce the generation or manage it, ensuring that the system remains stable. By focusing on the output of the generators, operators can assess and respond to rapid changes in loading conditions effectively, maintaining the reliability of the power system.
