Web-based interface of chaotic swing dynamics in electric power systems

Abstract

Researchers have showed that bifurcation and chaos theory are a proper and applicable method to study the mechanism of producing cascading failure in a power system by numerous studies. Because of the need for this analysis of cascading failures in power system, we should use such chaotic models and bifurcations models which require strong mathematical background for nonlinear differential equation solution tools and iterative methods. In this context we can say that MATLAB® is a widely used strong computational environment for research and development many large applications continue to be developed and deployed using MATLAB. MATLAB has also enhanced toolboxes and is flexible environment for web platforms. Especially after releasing Deployment Project Toolbox, MATLAB simulations and calculation capabilities have generously been transferred into web environments especially using WebFigureControl component. Web platform is also a great chance for sharing nonlinear dynamics and chaotic modeling studies. These great gaps into literature directed us to transfer our nonlinear dynamics workings in electrical power engineering via web platform. By these thoughts, we have designed a chaotic simulation web portal that simulate and model our nonlinear power system analysis workings. In this study, we focused on a Two machine infinity bus (TMIB) power system model as case study. Key words: Power system, swing dynamics, chaos, WebFigureControl, web simulations.
