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