The Information Technologies (IT) industry has an increasing carbon footprint (2.1-3.9% of global greenhouse gas emissions in 2020), incompatible with the rapid decarbonization needed to mitigate climate change. Data centers hold a significant share due to their electricity consumption amounting to 1% of the global electricity consumption in 2018. ...
The current energy crisis has revealed deep vulnerabilities in energy supplies. It also emphasised the strong fossil fuel dependency of many countries. Some governments decided to tighten their energy policies, particularly on energy efficiency and the use of intermittent and renewable energies. Photovoltaic energy has the advantage of emitting few ...
This thesis addresses critical aspects of enhancing the performance and longevity of energystorage systems (ESS) in electric vehicles (EVs). The first chapter provides an exhaustive review of thecurrent state-of-the-art in Energy Storage Systems (ESS) designed for electric vehicles. This encompasses a comprehensive analysis of various technologies,...
This research study explores control strategies for energy systems, giving due consideration to human involvement and personal preferences, dissatisfaction,and motivation. The aim is to create a paradigm shift from traditional approaches where control strategies often overlook the behaviour of people. As an alternative, this study introduces the ac...
Les micro-réseaux sont considérés comme l'avenir de la production d'énergie et de la distribution dans les réseaux électriques. Beaucoup d’entre eux comportent une production photovoltaïque et un stockage, le plus souvent sous forme de batteries, pour alimenter différentes charges. Cette thèse a pour objectif principal de proposer des stratégies de...
Le laboratoire PIMENT a développé un outil de gestion de la consommation électrique d’un logement, un modèle à variables mixtes (MILP) dont la première approche fut de linéariser un modèle non linéaire définissant le mode d’utilisation des appareils électriques pour un îlot de maisons. Basé sur une plateforme de communication développée sous Androï...
Frequent and long-duration stochastic grid outages are very common in developing countries, thus posing unbearable power supply reliability problem. Customers are often forced to use diesel generators to overcome these unpredictable and recurrent outages. This thesis proposes a solar photovoltaic and battery multi-source system integrated to a weak...
Islanded microgrids, a power generation scheme at the local level, are gaining interest in electrifying the bottom of the social pyramid. However, such systems are financially risky for grid managers due to less return on investment. Therefore, affordable energy access will continue to remain a pressing issue for more than 8% of the world's populat...
Ce travail de thèse s’inscrit dans le cadre de la contribution à l’avancée scientifique et technologique de l'utilisation des énergies renouvelables au moyen d'un système de piles à combustible PEMFC alimenté par de l'hydrogène provenant d'un réservoir à hydrure métallique. La première partie du travail a été consacrée à la caractérisation de deux ...
The application of hybrid power system in the field of transportation can alleviate environmental pollution problems and improve air quality. Therefore, this thesis is devoted to researching energy management strategies and power distribution methods suitable for hybrid power systems with different power levels. In the hybrid power systems, the hig...
