Static security assessment in deregulated power system using artificial inteligence techniques

The basic function of an electric power system is to supply customers with electric energy as economically as possible and with a reasonable degree of continuity and quality. Deregulation of power system in recent years has turned static security assessment (SSA) into a challenging task for which ac...
