Analytical static voltage stability boundary based on holomorphic embedding

International Journal of Electrical Power & Energy Systems, 2022
Abstract This paper proposes a novel analytical method to calculate the Static Voltage Stability Boundary (SVSB) for power systems as a hypersurface in a high-dimensional space on power flow solutions. First, the proposed method derives the analytical voltage solution of AC power flows in the form of Multivariate Power Series (MPS) using the ...
