An optimal tracking approach to load-frequency control

Abstract

This paper takes the view that the predominant problem of load frequency control (LFC) resides in the low frequency domain assosiated with bulk generation change and which is dominated by limited generation response capability. In this setting LFC is formulated as a tracking problem in which energy source dynamics and load following play a central role. It is shown how load prediction and coordination of area generation in a multi-area interconnection can effectively improve the regulation of inter-area power flows.
