STATIC CHARATERISTICS ANALYSIS OF POWER SYSTEMS THROUGH A HERMITIAN APPROACH

This paper formulates the power equations of power systems into the Hermitian power equations in terms of active/reactive power indices, based on which we complete two tasks: (i) constructing novel Newton-Raphson iterative algorithms for computing power flows of the power systems that include adjustable weighting coefficients; (ii) deriving possible eigenvalue/singular-value inequalities for nodal voltage evaluation with or without power flow computations. The results are significant in evaluating voltage stability of the power systems.
