Abstract :
In this paper the authors present an approach to enhance the security of power systems by supplementing optimal generation scheduling solutions for reducing branch overload in the case of contingencies. The supplementary control adjustment is determined by approximate reasoning based on qualitative rules and fuzzy sets. Fuzzy sets and reasoning procedure are defined for effective security enhancement of real power generation. Numerical examples prove that this approach yields more secure conditions against branch overload
