Perfectionnement des outils et pratiques de modélisation hydrologique pour l’évaluation des impacts des changements climatiques sur les régimes hydriques québécois

Les variations anticipées du climat pourraient venir perturber substantiellement le régime hydrique québécois, appelant les acteurs locaux de l’eau à redéfinir leurs modes de gestion ainsi qu’à mettre en place des stratégies d’adaptation. Les travaux engagés dans ce sens, initiés dans le début des années 2000 par Hydro-Québec, s’appuient dorénavant sur une collaboration (cQ2 : Hydro-Québec, CEHQ, Rio Tinto Alcan, Ouranos) visant à diffuser un message complet et cohérent quant au diagnostic des impacts sur les régimes hydriques en s’appuyant sur des bases scientifiques solides.

Advanced Computational Algorithms for Transient Stability Simulation Using Dynamic Phasors

The main objective of the proposed research project is to develop a new transient stability simulation method based on advanced computational and modeling techniques that is both fast and accurate. Transient stability studies are an important part of system planning and operation as they ensure that a system will maintain stable operation following severe disturbances. However, traditional simulation techniques were not designed for the size and complexity of modern power systems.

GOWL-Edit, un assistant logiciel pour l’édition graphique d’ontologies OWL 2, de requêtes SPARQL et de règles SWRL (Semantic Web Rules Language) dans la syntaxe G-OWL étendue

L’Institut de Recherche en Électricité du Québec (IREQ), qui est le centre de recherche d’Hydro-Québec, a pris le virage des technologies du web sémantique depuis quelques années. L’IREQ doit gérer une quantité énorme d’informations provenant de ses équipements réparties dans tous le Québec. Les chercheurs de l’IREQ ont notamment choisis les technologies du web sémantique afin de faciliter la cueillette et la gestion des informations. Au coeur des technologies de web sémantique réside une pile langagière qui permet de textuellement coder les informations et la sémantique qui s’y rattache.

Distribution feeder voltage control with a high penetration of distributed generation

In this project, a methodology for controlling the distributed generation resources connected to the distribution system level will be developed. This control strategy will improve the efficiency and reliability of the operation by decreasing the losses, managing the assets, and increasing the system reliability. There are currently several feeders in the BC Hydro distribution system with considerable amount of distributed generation installed. This has caused voltage problems at the feeder level and also control issues at the substation level.

Improving the efficiency of the supersonic binary fluid ejector using computational fluid dynamic modeling

The only commercially available technology that directly uses thermal energy to produce cooling is absorption chillers, which are not economical for small-medium scale buildings (<100,000 sq.ft.) and suffer from serious performance
limitations. May-Ruben Thermal Solutions (MRTS) is developing a novel Binary Fluid Ejector (BFE) that will provide a high-performance, economic, scalable, thermally-driven heat pump and refrigeration cycle. Early applications include

Impacts of hydroelectricity production on aquatic ecosystems: Development of key environmental indicators for Life Cycle Assessment (LCA) approach

In boreal and temperate regions, dams are mainly constructed to provide ecosystem services such as hydroelectricity production. River impoundment and the alteration of natural hydrological regimes are suggested to be major disturbances to aquatic ecosystems. To meet long-term environmental objectives for sustainable development, Hydro-Quebec recently adopted the Life Cycle Assessment (LCA) approach. LCA is an ISO standardized approach assessing the potential environmental impacts of product, services and processes throughout its entire life cycle.

Pollution control of gas mixtures: gas monitoring and detection of contaminants usingnovel THz technology

Electric power plants are the number one toxic air polluters in North America. The emitted pollutants are proven to cause serious health and environmental issues. The emission of Carbon dioxide and of other pollutants, such as nitrogen oxides, sulfur dioxide - major drivers of the human-accelerated global climate change- must be monitored insitu. Our goal for the present project is to explore the properties of Terahertz radiation for control of pollution in the atmosphere. In particular, we intend to develop a new waveguide-integrated gas monitor, based on Bragg grating sensors.

Initial Investigation of the Synthesis andCharacterization of Novel Core-Shell Pt Catalysts

Presently, platinum (Pt) nanoparticles are required to catalyze the desired redox reactions at the anode and cathode of proton exchange membrane fuel cells (PEMFCs). The high cost of this precious metal catalyst remains a barrier to the wide spread commercialization of PEMFCs, particularly for automotive applications. In an effort to reduce the Pt loading in PEMFCs, this research project is focused on the design of novel catalysts which consist of depositing a 1-2 monolayer “shell” of Pt onto a less expensive metal which acts as a “core”.

Developing 3D GIS Web Services and Applying It in Oil and Gas Pipeline GeographicalInformation System

Currently, developing 3D pipeline GIS (Geographical Information System) with 3D data interoperability is not only highly required by pipeline industry but also essential for building 3D SDI (Spatial Data Infrastructure). This project proposes a novel approach to develop a new 3D GIS Web Services framework and components that is suitable for 3D Pipeline GIS and 3D SDI. The specific objectives of the project are to:

1) Develop a new 3D GIS Web Services framework that is suitable for 3D pipeline GIS considering its data feature.

Engaging stakeholders to evaluate alternatives in energy system planning through agentbased automated negotiation

The objective of this project is to improve long-term planning of Alberta's electricity system infrastructure in collaboration with an industry sponsor, Alberta Electricity System Operator (AESO). The project aims at engaging stakeholders in a regional planning exercise in southern Alberta by a detailed exploration of their perspectives when evaluating energy system alternatives. This was identified by AESO as being a pressing gap in their current practice.
