An Integrated Approach for Optimizing Dynamic Transfer Limits at Hydro-Quebec

This paper presents the approach elaborated by Hydro-Quebec TransEnergie (Hydro-Quebec´s transmission division) in collaboration with Hydro-Quebec´s Research Institute (IREQ) to improve the dynamic transfer limits of its transmission system in the coming years. The evaluation of these limits is mainly related to transient and voltage stability problems. As the complexity of the network increases, so does the number of studies required to determine transfer limits. The proposed approach provides an integrated process for power system operation planning engineers to establish secure transfer limits in a shorter lead time. 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.
