Development of an algorithm for compressing the information content of the results of the continuation power flow analysis

Abstract

Abstract In this work, we have developed an algorithm to compress the information content derived from the Continuation Power Flow (CPF) analysis. We utilized MATLAB as the computational tool, which made it possible to display the results graphically in a simple manner. This paper presents a schematic representation of the developed algorithm, followed by a step-by-step explanation using a theoretical and practical example based on the algorithm's schematics. We employed synthetic high-voltage grids ranging from 2 to 17 nodes as test systems. Future work will focus on the development of software that can be applied to any network. Our investigations have revealed several advantages of CPF. It enables the analysis of system behavior in both stable and unstable regions, providing precise information about the load level at which voltage collapse occurs. This accuracy is contingent on a consensus that voltage collapse can be described using a stationary approach. Additionally, CPF analysis results, particularly the PV curves, are easily interpretable with appropriate graphical processing. We present the results of voltage stability analyses, graphically displaying voltage magnitudes and angles as they vary with the load for networks of different sizes, ranging from 2 to 17 nodes, calculated using CPF.
