This paper describes the innovative concept of a electromechanical approach for recognition the identical behaviour of machines for various power system disturbances. This aspect is used as a basis for generating nonlinear dynamic equivalents which can be applied in transient stability studies incorporating the physical model parameters of the generators. The approach is developed on the basis of the identity conditions, which are solved using standard pattern recognition algorithms. The principal property of this approach consists of the introduction of an electromechanical distance that it significantly improves the accuracy and efficiency of calculating identity-based dynamic equivalents and thereby enhances their consistency, effectiveness and application.Test of these approach have been performed and evaluated in large-scale model of the European Interconnected Electric Power System (western European Union for the Coordination of Transmission of Electricity (UCTE), the central European power system (CENTREL)).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
