Investigation of Decision Trees (DTs) parameters for power system voltage stability enhancement

Abstract

This paper describes the application of Decision Tress (DTs) in order to specify the most critical location and the rate of series compensation in order to increase power system loading margin. The proposed methodology is applied to a projected model of the Hellenic interconnected system in several system configurations. Investigation of the best system operating point to create the DTs, the effect of attributes number and type on the DTs size and quality are discussed in order to reach the final DTs parameters that lead to the construction of the best DTs for the determination of optimal series compensation location and rate. Finally, the results obtained for several (N-1) contingencies examined are presented. © Springer-Verlag Berlin Heidelberg 2006.
