Abstract :
The author summarizes the research conducted in two projects funded by the NSF program in power systems. The projects deal with extending the applications of the transient energy function (TEF) method. The TEF method is a direct method for the transient stability analysis of power systems. The work done in these research efforts consisted of the incorporation of detailed generator models and excitation control in the TEF method, inclusion of network information, development of analytical sensitivity techniques, and parallel implementation of the TEF algorithm. This project consisted of the development of a parallel version of the TEF algorithm on an IBM 3090-600E supercomputer. A step-by-step procedure to convert the sequential code to a parallel environment was developed. With six parallel processors an elapsed time speed up to 5.36 was obtained. The developments in these projects have been tested on several realistic, large-scale power systems. A sample of these results is presented
