This paper presents a method, using data mining techniques, to find dynamic power transfer limits and sensitivity of the limits due to element variations for the Hydro-Quebec power system based on topology information. The paper illustrates a systematic way to automatically generate a tremendous amount of cases to represent a wide range of parameter variations and compute their corresponding transfer...
Hydro-Québec has a long interest in on-line dynamic security assessment (DSA) necessitated by its challenging power network dynamics (transient, fast and slow voltage collapse). We are presently using off-line calculated security indicators and an on-line monitoring system approach. Every 5 seconds our system provides dynamic security limits, the impact of each out-of-service component, simple guidelines...
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...
