An enhanced expert system with fuzzy reasoning for line flow control in power systems

This paper presents an enhanced expert system for line flow control in power systems. The preventive mode dealing with both pre-contingency and post-contingency constraints is considered in this enhanced expert system. The presented expert system is achieved through integration of an existing expert system and the fuzzy set theory. The IEEE 30-bus system and a practical 265-bus system in Taiwan are used to serve as samples to show the applicability of the proposed expert system in this paper.
