Analysis and Design of a Controller for an SMIB Power System via Time Domain Approach


Background/Objectives: Designing a large interconnected system and to guarantee the system stability at a minimum cost is of very challenging task. From control theory point of view, a power system is a higher order multivariable process which operates constantly in a changing environment. Hence, it is necessary to perform the order reduction, for such a complex system. Methods/Statistical Analysis: In this paper order reduction techniques i.e. Modal Analysis Approach and Aggregation methods have been used to diminish the stable higher order system to a stable demoted order model. Findings: During approximation, the uniqueness of the original system are conserved in its demoted order model. Application/Improvements: The response of the demoted order model has been improved by designing a controller using pole placement technique.
