This paper proposes a new method for designing decentralized interaction estimators for interconnected large-scale systems and utilizes it to multi-area power systems. For each local area, a local estimator is designed to estimate the interactions of this area using only the local output measurements. In fact, these interactions are the information of other area. A new scheme is developed to construct an approximate model for the interaction dynamics and design a local estimator. The designed local estimator exploits the model of each area and its actual inputs and outputs to produce a good estimation of unknown states and interactions. It is shown that in the proposed method the errors of estimation are globally ultimately bounded with respect to a specific bound. Our scheme is used to design decentralized estimator for a three-area power system to illustrate the effectiveness of the proposed method.}, keywords = {Multi Area Power System,Load Frequency Control,Large Scale Systems,Estimation}, url = {https://www.ije.ir/article_71472.html}, eprint = {https://www.ije.ir/article_71472_d7f783096621077673cf3dc0b6de1bd0.pdf} }
