This panel presentation discusses the development of a symbolic numeric steady state power flow model suitable for fast and comprehensive contingency analysis. The model uses sparse polynomial presentations of the branch outages. Results are presented for the IEEE 118 and the IEEE 300 test system
This panel contribution presents an integrated approach that combines symbolic and numeric computations to investigate dynamic analysis and simulation issues in power systems. Power system studies including load flow and local bifurcation analysis, require the numerical solution of non-linear equations using the Newton-Raphson-Seydel technique. This algorithm requires the computation of higher order...
This paper presents a Matlab-based voltage stability toolbox (VST) designed to analyze bifurcation and voltage stability problems in electric power systems. VST combines proven computational and analytical capabilities of bifurcation theory, and symbolic implementation and graphical representation capabilities of Matlab and its toolboxes. The motivation for developing the package is to provide a flexible...
This paper describes the history and use of symbolic computation in power systems, from the tools used for power system analysis such as power flows, to its application in the class room to facilitate the explanation and understanding of complex models and concepts such as device modeling and simulation. An example of the use of symbolic computation to develop a basic power flow program with the help...
