To ensure the power market in North America operates fairly and efficiently, the North American Electric Reliability Corporation (NERC) has developed a reliability functional model that serves as the basis for the development and implementation of its reliability standards. This functional model sets out a number of roles, attributed to various functional entities, with respect to the development and operation of interconnected power systems in Canada and the USA.
In Québec, Hydro-Québec’s TransÉnergie plays a dual role in terms of system planning.
- As Planning Coordinator, it coordinates and integrates plans for short-term power transmission.
- As Transmission Planner, it develops a long-term plan for the transmission system.
This dual role requires TransÉnergie to keep updated models of the Québec transmission system to conduct transmission system planning studies and reliability analyses.
The accuracy of system models depends largely on the reliability of the modeling data collected from the various functional entities that are part of the Québec transmission system. These entities include the reliability coordinator (undertaken by the Direction – Contrôle des mouvements d’énergie et exploitation du reseau) and all owners or operators of an electric power transmission system or generation facility connected to the Québec transmission system.
The document “Transmission System Modeling Data Requirements and Reporting Procedures” lays out the steady-state, dynamic and short-circuit modeling data requirements along with their reporting procedures, in keeping with NERC reliability standard MOD-032-1 — Data for Power System Modeling and Analysis.
The document shall serve as a reference guide to all functional entities that provide Hydro-Québec with data needed for system modeling.
