Abstract

Accurate simulation of power-systems dynamics over an extended time period results in a model that is relatively stiff; the solution of such models requires a numerical integration method that is not only fast and accurate, but also capable of using long time steps. An integration method which can be numerically tuned to suit the system of equations is developed and is shown to be superior to the trapezoidal rule when very long time steps are used. While the fixed-tuning methods are easy to implement, they are not recommended since they resulted in no significant improvements. Adaptively tuned techniques performed better and some worthwhile gains were obtained with long time steps
