Real-time co-ordination of facts devices set-points

Abstract

An algorithm for co-ordinating set-points of FACTS devices is proposed in this paper. This co-ordination is developed in order to eliminate overloads of lines in normal operation and after disturbances, and thus to increase security margins of the system in real-time operation. The proposed algorithm is based on sequential adaptive adjustment of FACTS devices set-points. Values of the set-points are obtained on the base of an on-line optimisation procedure. Proposed algorithm is tested on a multimachine bulk power system. Obtained results show the efficiency of this approach in system co-ordination.
