This paper presents a new method of designing decentralized discrete-type load-frequency regulator with controlling delay of one sampling time for interconnected power systems. In this paper, the interconnected multi-area electric energy system is decomposed into several subsystems, each of which is controlled separately by using a local feedback only. An especially attractive feature of the proposed control scheme is that it requires as feedback signals accumulative quantities of the area control error on the basis of linear quadratic integrating technique. An additional feature is that it considers the time delay due to the computation time of the control law and the transmission time of the system date over the telemeter links to the controlling plant. The proposed control scheme is illustrated by digital simulation of a 2-area system provided with reheat steam turbines. The results show that this discrete-type regulator can act satisfactorily for improving dynamic responses of the load-frequency control.
