Load Frequency Control (LFC) is a crucial process in power systems that maintains the balance between electricity supply and demand. It ensures that the frequency of the electrical grid remains stable, typically around 50 or 60 Hz, by adjusting the output of generating units in response to changes in load. When there is an increase in demand, the frequency tends to drop, prompting LFC to increase generation. Conversely, if demand decreases, the frequency rises, and LFC reduces generation. This automatic adjustment helps prevent blackouts and ensures a reliable power supply for consumers and industries.
