Design of Decentralized Load-Frequency Controllers Using Pole Placement Technique

This paper presents a new procedure for the design of decentralized load-frequency controllers for an interconnected power system using a pole placement technique. This technique is based on a new algorithm which assigns desired poles using decentralized constant gain feedback. It is assumed that all the local state informations are available for feedback in each area. The proposed design procedure is conceptually simple and computationally attractive. As the poles of the system are directly handled during the design, it guarantees closed-loop stability of the overall system. The proposed technique is applied to a two-area interconnected power system. The results demonstrate the usefulness of the proposed design.
