Principal component analysis applied to continuation power flow

Abstract

This paper analyzes the applicability of Principal Component Analysis (PCA) to study the high voltage solutions of Continuation Power Flow (CPF). A simulation based process is used for data generation and subsequent PCA application with their results analysis. The simulation considers a single bus – load equivalent and controlled variation of the equivalent system impedance behind the load. Variations of data structure are proposed and analyzed in order to interpret results from power system perspective and exploration about possible hidden correlations obtained from PCA application. Finally, on the basis of these correlations, the analysis of clusters is discussed.
