Voltage Stability Kernel: A Cofactor Theory of Voltage Stability in Lossy Power Systems

Takayuki Ishizaki, Jigen Koizumi, Hiroo Yashiba, Boqiang Sun

This paper introduces the voltage stability kernel (VSK), a cofactor-based bus-wise representation of voltage stability in lossy power systems. The VSK is defined as the vector of principal cofactors of the voltage stability Laplacian (VSL), a reduced Jacobian that retains voltag…Read more
