Hydroelectric turbines vibrate when they operate, due to their rotation in water. Those vibrations, if not studied and looked after, may damage the runners as well as the shaft, resulting in a decrease of production and operating range, and in a faster deterioration of the components too. Therefore, this project aims to study the vibrations […]

This project studies network capacity and throughput for newly emerging MSGN infrastructure including mesh planning strategies and how the number of hops and end-devices affects the overall throughput. The work includes developing the analytical framework, and confirmation through simulation and physical experiment, of proof-of-concepts in the smart utility lab IPv6 RF mesh test bed. During […]

Ce stage de recherche vise le développement et le transfert de connaissances dans les domaines de la gestion de projets d’innovation complexes et la collaboration intraorganisationnelle à distance. Plus spécifiquement, le stage permettra d’appuyer une société d’État québécoise dans son processus de décision visant à évaluer et sélectionner des mécanismes de collaboration à distance dans […]

Increasing demands for electric vehicles and more portable electronics have also increased the demand for rechargeable batteries with higher energy capacity. This project aims to develop novel manufacturing methods to produce advanced rechargeable batteries in a time and cost-efficient way. In this project, the interns perform hands-on experiments to investigate the application of the novel […]

Lithium-ion batteries (LIBs) are commonly used for electric cars and portable electronic devices. In order to make these devices cheaper, lighter and more accessible, high capacity LIBs are needed. Lithium or silicon are ideal materials for LIBs due to their high specific capacity. However, they cannot be used to substitute the graphite anode in the […]

Le projet vise a moderniser et ameliorer les outils numeriques utilises par Hydro-Quebec pour prevoir la demande en electricite au Quebec et mettre en ceuvre des strategies d’autocorrection. Les developpements attendus permettront d’augmenter la capacite de maintenance et d’amelioration de ces outils par Hydro-Quebec, et de les rendre plus efficaces. Hydro-Quebec sera ainsi plus à […]

The growth of renewable energies on the demand side, as an important step for decarbonization and transition to the smart grid, poses serious challenges to control the system and maintain stability. Transactive energy control (TEC) is introduced as an effective approach in which distributed control methods are utilized rather than centralized ones. Although many studies […]

Occupant thermal comfort and ventilation drive the operation of HVAC (heating, ventilation, and air conditioning) systems in buildings, which consume a large portion of their energy use. “Human-in-the-loop” (HITL), a term borrowed from machine learning referring to a synergy between humans and machines, is a data-driven approach that aims to enable human-based controls of the […]

Ce projet traite le défi de simulation collaborative d’un modèle de réseau électrique qui comporte plusieurs composants hétérogènes, tels que les RÉD (Ressources Énergétiques Décentralisées), les VÉ (Véhicules Électriques) et les automatismes numérisés selon le standard CEI 61850. Puisque l’intégration de ces éléments complexifie le modèle simulé de réseau électrique, l’idée est de les intégrer […]

Le but du projet est caractériser les efforts que subit les roues de turbines hydroélectriques à partir de leurs données d’opérations en production d’électricité. À long terme, le projet permettra de combiner les méthodes de conception par modélisation numérique et par analyse empirique pour caractériser plus précisément les efforts que subit la roue. On pourra […]

In warm climates warm temperatures cause thermal stratification in hydropower reservoirs inhibiting mixing and leading to deoxygenation of waters at depth (hypolimnium). Turbines withdrawing water at depth result in low dissolved oxygen (DO) in the downstream flow having a large negative impact on the downstream riverine ecosystem. Legislation in the USA and elsewhere now requires […]

The battery is an electrochemical device that people use every day. The industry is always interested in improving different characteristics of batteries such as less cost, increasing power, safety, and eco-friendliness. Nickel metal hydride (NiMH) batteries are widely used rechargeable power sources. We work on the replacement of aggressive electrolyte used in this technology by […]
