An integrated approach for optimizing dynamic transfer limits at Hydro-Quebec

This publication presents the approach elaborated by Hydro-Quebec TransEnergie (Hydro-Quebecpsilas transmission division) in a collaboration project with Hydro-Quebecpsilas Research Institute (IREQ) to improve the dynamic transfer limits of its transmission system. The evaluation of these limits is mainly related to transient and voltage stability problems. The proposed approach provides an integrated process for power system operation planning engineers to establish in advance secure transfer limits. These limits are optimized for specific power system configurations under constrained operating conditions. Faster and more rigorous methods have been developed in the integrated process.
