Recent and Sophisticated Developments of Long-Term Dynamic Modelling for the Reconstruction of Real Incidents in the Enel Power Systems

Abstract Among the several needs of electric power system analysis, having the final object to more and more improving the quality and the continuity of the service, the one related to "long-term dynamics" has reached, especially in the last years, a very important function. The paper describes in qualitative terms the recent and sophisticated improvements concerning both the modelling and the digital code, named STRALE, developed by ENEL and specifically oriented to operational-planning and operation studies, in particular to the reconstruction of real incidents.
