STAG-a new unified software program for the study of the dynamic behaviour of electrical power systems
TLDR
In this article, a program is developed for the numerical simulation of dynamic phenomena in power systems, which unifies the conventional fields of transient, mid-term and long-term stabilities.Abstract:
A program is developed for the numerical simulation of dynamic phenomena in power systems. This program unifies the conventional fields of transient, mid-term and long-term stabilities. The integration algorithm ensures a constant level of accuracy in the calculation of fast or slow transients through a continually variable step and through suitable numerical stability properties. The performance levels reached, both as regards ease of utilization and the size and complexity of the simulated systems, allow the majority of cases to be covered so far as the dynamic system behavior study requirements of the Belgian power companies are concerned. >read more

TL;DR: The EPRI Transient/Mid-term Stability Program was enhanced to allow a long-term operating mode where integration steps out to one second can be used as mentioned in this paper, and the program automatically reverts to and from the short-term and longterm modes according to the short term and long term conditions according to prevailing system conditions.
