Storage system performance has received much attention since the early days of computing systems because of the mismatch between computing power and I/O access times. The invention of new technologies have increased storage system performance, but due to the cost-performance trade off no one type of storage media is capable to meet both performance and capacity requirements. This motivated us to study the impact of data management techniques such as data partitioning and correlated prefetching on I/O performance when two different non-volatile storage media are integrated into a computing syst

Ces travaux de thèse portent sur l'étude de matériaux d'électrodes de supercondensateurs. Ce sont des dispositifs de stockage qui possèdent une densité de puissance importante de l'ordre de plusieurs kW/kg. Des systèmes asymétriques ont été développés dans le but d'augmenter la densité d'énergie de ces dispositifs, tout en essayant de maintenir une densité de puissance élevée. Ils font intervenir une électrode capacitive classique de carbone activé et une électrode faradique. Concernant cette électrode non-bloquante, deux orientations ont été abordées : • Principalement, l'utilisation de titan

La sfida di integrare la potenza intermittente proveniente da fonti energetiche rinnovabili nella rete elettrica non può essere considerata come un problema isolato, ma deve essere visto come uno strumento per integrare e mettere in primo piano i sistemi energetici rinnovabili. Questo progetto di tesi di dottorato presenta l'analisi, lo studio e lo sviluppo di un software ad interfaccia web in grado di progettare sistemi energetici ibridi in qualsiasi luogo del mondo, in grado di migliorare l'affidabilità, la disponibilità e la sostenibilità sia di sistemi connessi alla rete che di sistemi is

Numerous countries are trying to reach almost 100\% renewable penetration. Variable renewable energy (VRE), for instance wind and PV, will be the main provider of the future grid. The efforts to decrease the greenhouse gasses are promising on the current remarkable growth of grid connected photovoltaic (PV) capacity. This thesis provides an overview of the presented techniques, standards and grid interface of the PV systems in distribution and transmission level. This thesis reviews the most-adopted grid codes which required by system operators on large-scale grid connected Photovoltaic system

Backup diesel generator (DG) systems continue to be a heavily polluting and costly solution for institutions with unreliable grid connections. These systems slow economic growth and accelerate climate change. Photovoltaic (PV), energy storage (ES), grid connected, DG – Hybrid Energy Systems (HESs) or, PV-HESs, can alleviate overwhelming costs and harmful emissions incurred from traditional back-up DG systems and improve the reliability of power supply. However, from project conception to end of lifetime, PV-HESs face significant barriers of uncertainty and variable operating conditions. The fi

The transition to a low-carbon future necessitates innovative approaches to carbon management and hydrogen storage, particularly in the context of enhanced oil recovery (EOR) from hydrocarbon reservoirs. This study employs advanced analytics and machine learning techniques to optimize carbon management strategies. One key focus of this research is to evaluate the effectiveness of flue gas and CO2 in Water Alternating Gas (WAG) injection within a homogeneous fractured carbonate reservoir characterized by low porosity and permeability. A computational model was developed to depict the flow regim

Cette thèse présente un modèle unique du MASG (Modèle d’Architecture du Smart Grid) en considérant l 'état de l’art des différentes directives de recherche du smart grid. Le système hybride de génération d'énergie active marine-hydrogène a été modélisé pour représenter la couche de composants du MASG. Le système intègre l'électrolyseur à membrane d’échange de proton (à l’échelle de méga watt) et les systèmes de piles à combustible en tant que composants principaux du bilan énergétique. La batterie LiFePO4 est utilisée pour couvrir la dynamique rapide de l'énergie électrique. En outre, la thèse

Comparé au réseau électrique alternatif (AC), le réseau électrique en courant continu (DC) a démontré de nombreux avantages tels que son interface naturelle avec les RES, les systèmes de stockage d'énergie et les charges en courant continu, une efficacité supérieure avec moins d'étapes de conversion, et un contrôle plus simple sans effet de peau et sans considérations sur le flux de puissance réactive. Le micro-réseaux DC reste une technologie relativement nouvelle, et ses architectures de réseau, stratégies de contrôle, techniques de stabilisation méritent d'énormes efforts de recherche. Dans
