Abstract

This paper presents a detailed analysis of the dynamic behaviour under large disturbances of a high voltage DC electric power system representative of the power distribution networks which are commonly being proposed for future ldquomore electricrdquo vehicles. Numerical simulations are undertaken to analyze the region of asymptotic stability of the system under different operating conditions. Analytical derivations based on the use of the Brayton-Moser Mixed Potential are employed along with Lyapunov stability theorems to determine an analytical estimation of the stability region.
