The models required for power system dynamic analysis are continually growing larger and more complex as power system interconnections are growing more significant. The purpose of this research is to improve both the efficiency and reliability of today's simulation, and to lead to a capability to perform the more complex simulation of tomorrow. The approach taken was to identify the fundamental characteristics of dynamic power system models, and to relate these to candidate numerical methods. The performance characteristics of the methods were analyzed for efficiency, reliability, and stability. Finally, extensive testing was performed on selected test cases (smaller cases were tested first, with testing on larger cases now proceeding) to identify the best computational procedures for solving power system dynamic problems. A diagnostic transient stability program has been developed to perform this testing. This program not only performs transient stability computation, but also analyzes the performance of the numerical methods. The diagnostic program, developed entirely on this research project, is presently being documented for use by other researchers. Conclusions of this first phase include specific recommendations of integration methods, step size requirements, and algebraic solution methods which will provide the basis for a new industry standard transient stability program. Recommendations are also included that will be useful for improving the efficiency and reliability of existing stability codes with minimal changes required.
