英文摘要	The stable results are obtained through the existed voltage stability, but few studies are related to the key factors affecting the system voltage stability, the margin sensitivity analysis based on Continuation Power Flow (CPF) was performed, and the voltage stability index was derived by the combination of the tangent vector around the critical point and the right eigenvector and the right singular vector. This index was used to describe the critical factors affecting the voltage stability of the system. The calculation of the load margin sensitivity with respect to excitation system parameters, network parameters and load parameters was obtained by estimating the transfer margin. The simulation results on the IEEE-39 bus system show the proposed calculation method of the load margin sensitivity with respect to the typical parameter can be used to estimate the voltage stability margin under the system parameters changing situation, determine the system voltage stability sensitive nodes, select the most suitable position of reactive power compensation and determine the best cutting load to maintain voltage stability. ©, 2015, Editorial Department of Electric Machines and Control.
