Abstract
Singular value decomposition method combined with continue power flow method has been applied to the analysis and prediction for voltage steady-state stability limit of Sichuan power grid in this paper. Calculation and analysis for operational parameter of Sichuan power grid in 2003 have been carried out
from which the effective information of voltage steady-state stability margin has been obtained and the weakness nodes and the most sensitive control direction have been found out as well.
