Abstract

SPIRA-SICRE: an integrated software tool for static and dynamic analyses of large power systems P. Baratella, F Casamatta & R. Zacheo CESI Spa, Milano, Italy. Abstract The scenario for power systems has greatly changed in recent years following the liberalisation of the electricity market. The main consequences are a greater interconnection level (with increased cross-border exchange) and an exploitation of the capability of the network components close to their technical limits. Therefore, to keep the pre-established reliability indexes and security levels, very accurate analyses need to be carried out. These are related to optimisation functions and dynamic studies. The optimisation functions are aimed at assuring minimum cost solutions when comparing different alternatives and probabilistic algorithms to take into account all the uncertainties that characterise this type of study. Dynamic analyses are devoted to investigating the behaviour of the electric systems at
