Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
This paper presents a hybrid energy storage system mainly based on Compressed Air, where the storage and withdrawal of energy are done within maximum efficiency conditions. As these maximum efficiency conditions impose the level of converted power, an inte ...
An increasing recourse to renewable energies is one of the key solutions to address the current resource and environmental concerns related to the world energy supply. Because of the distributed and intermittent nature of several of them (Solar, Wind), an ...
Environmental energy is becoming a feasible alternative for many low-power systems, such as wireless sensor nodes. Designing an environmentally powered device faces several challenges: choosing the exact type of the energy harvester, the energy storage ele ...
Proton exchange membrane (PEM) fuel cells show characteristics of high power density, low operating temperature, and fast start-up capability, which make them potentially suitable to replace conventional power sources (e.g., internal combustion engines) as ...
The paper deals with a microgrid test facility, settled at the CESI RICERCA laboratories, equipped with various distributed energy resources (DERs) and connected to a LV network. The operation of such a microgrid is supervised by a central automatic microg ...
Supercapacitors are new and powerful components for energy storage. Compared with batteries, the amount of energy they can store is low. But, as power sources they have the property to be re-loadable in a few seconds [1][2][3]. In that case, the needed ins ...
A new methodology is presented, based on energy-flow analysis on systems. The aim is to obtain a representation of energy flows between the various sources of a complex system, via energy storage devices connected together with electrical and mechanical co ...
A downscaled drive train with a 6.5 kW fuel cell and a 10 kW supercapacitor module was realized and tested. The voltage levels and the energy flow between fuel cell and supercapacitor were controlled by an electronic unit. The combined fuel-cell/supercapac ...
This report presents the field tests synthesis of a small Hybrid Solar Power Plant integrating three technologies : hermetic volumetric scroll expander - generators working with two superposed Organic Rankine Cycles (ORC) a cogeneration group composed by a ...
Fuel Cells are destined to supply electric energy beginning from primary resources. A static DC-AC converter is necessarily inserted between the fuel cells and the distribution network. This paper describes a new P.W.M. strategy for a current source invert ...
