What effect does an increase in load have on a generator’s frequency?

An increase in load on a generator typically leads to a decrease in frequency. This phenomenon occurs because generators are designed to operate at a specific frequency, often 60 Hz in North America. When the demand for electricity increases (an increase in load), the generators must work harder to supply the additional energy. However, if the pace at which the generators can produce power does not match the rising demand, this imbalance can result in a drop in the system frequency.

As the generator struggles to keep up with the demand, it may not be able to maintain the rotational speed required for the designated frequency, thus causing the frequency to decline. This underscoring of frequency is a crucial aspect of maintaining grid stability, as a significant dip in frequency can lead to operational issues and possible cascading failures if not addressed promptly.

The other options do not accurately represent the relationship between load and frequency in power generation. Increased load leading to no effect on frequency, an increase in frequency, or immediate shutdown inaccurately depicts the standard operational behavior of generators concerning load changes.
