An integrated design of robust decentralized observer and controller for load frequency control
<|reference_start|>An integrated design of robust decentralized observer and controller for load frequency control: This paper focuses on designing completely decentralized load frequency control (LFC) for multi-area power systems to achieve global optimized performance. To this end, a new concept of integrated design is introduced for designing the decentralized LFC observers and controllers simultaneously off-line, by taking into account of the interactions between areas and the bidirectional effects between the local observer and controller in each area. The integrated design in this paper is realized via $H_\infty$ optimization with a single-step linear matrix inequality (LMI) formulation. The LMI regional eigenvalue assignment technique is further incorporated with $H_\infty$ optimization to improve the closed-loop system transient performance. A three-area power system is simulated to validate the superiority of the proposed integrated design over the conventional decentralized designs.<|reference_end|>
