Load-frequency control
Load-frequency control (LFC) is a type of integral control that restores the system frequency while respecting contracts for power provision or consumption to surrounding areas. The automatic generation scheme described in § Frequency and load establishes a damping that minimizes the magnitude of average frequency error, Δf, where f is frequency, Δ refers to the difference between measured and desired values, and overlines indicate time averages.
