Abstract

In this paper, we propose a comprehensive algorithm for identifying alternative solutions in power flow analysis. Our approach considers various power system conditions and grid sizes, from small to large-scale cases. By analyzing the Jacobian matrix and its singularity, we accurately detect the proximity to voltage collapse and identify alternative solutions. The results demonstrate the effectiveness of the algorithm in handling diverse scenarios and showcasing its capability in identifying alternative solutions in power flow analysis.

Keyphrases: Jacobian, PV-PQ - curves, alternative solution, ill-conditioned system, voltage stability
