Area load-frequency control
Abstract
Four basic objectives of load-frequency control (LFC) are discussed: (1) total-area generation should be controlled so as to track the area load plus schedule; (2) the individual-unit generations should be controlled so as to track the desired unit economic trajectories; (3) load-frequency control should allow the area primary response to occur naturally; and (4) individual-unit response rate limitations must not be violated. The parallel structure of LFC is exploited by designing independent controllers for each generating unit and a coordinating controller for the control area. These two components of the LFC structure are discussed and evaluated using a combination of the linear-quadratic-Gaussian (LOG) synthesis techniques, linear simulation, and frequency domain analysis.
