A Robust Solution for PI-based LFC Problem with Communication Delays

抄録

This paper addresses a new method to design a PI-based load-frequency control (LFC) with communication delays. First the LFC problem is reduced to a static output feedback control synthesis for a multiple delays system, and then the control parameters are easily carried out using robust H_∞ control technique. A 3-control area power system example is given to illustrate the proposed control methodology and the results are compared with the H_∞-based delay-less control system design.
