Abstract

This paper addresses the problem of dispatching active and reactive power on a large interconnected power system to maintain security. It models operator heuristics in the decision making process by means of fuzzy sets. Sensitivity analysis is then used to derive the necessary movements in control settings within a practical expert system that seeks a low cost, low number-of-controllers solution. Results are presented for a 20 machine, 100 bus reduced model of the UK national grid. Comparisons are shown with a linear programming approach and a conventional production rule based expert system implementation. The flexibility of the new approach is demonstrated whereby it can be used to model any number of operational criteria
