Abstract:
Afin de réduire les émissions de polluants et de CO2 les constructeurs automobiles se tournent de plus en plus versdes solutions de chaîne de traction électrifiées. Cette électrification des véhicules augmente la complexité des systèmes à concevoir. Les outils MBSE basés sur une approche système peuvent être utilisés pour gérer cette complexité grandissante. Une optimisation globale nécessite de s’intéresser aux trois niveaux de conception suivants : architecture, composant et contrôle. L’objectif de cette thèse est de développer une méthode d’optimisation globale pour la conception de système

Abstract:
This thesis discusses the operational coordination of electrical appliances and devices in a smart home. At present, the diminishing volume of fossil fuels and the increasing pressure to use renewable sources of energy necessitate the integration of such volatile sources into electrical grids. This process, however, results in higher energy costs, and the consumers are thus more willing to change their behaviour to either reduce the expenses or maintain them at a reasonable level. One of the relatively few customer-oriented options to optimise energy costs consists in the demand – response pri

Abstract:
The main aim of this thesis is to create a sequence of mathematical optimization models with different levels of complexity for the efficient management and waste energy utilization. Stochastic programming approach was utilized to deal with random demand and uncertain heating values. Hence, more applicable model of the waste-to-energy plant has been developed. As the next step, the model is enhanced by heating plant extension. Computations are realized for real-world data and optimal solution is found by using GAMS implementation.

La consommation d’énergie est devenue l’un des principaux problèmes d’urbanisation et de crise énergétique, car l’épuisement des combustibles fossiles et le réchauffement climatique mettent en péril l’utilisation de l’énergie des plantes. Cette thèse présent une méthode d’économie d’énergie a été adoptée pour la réduction de consommation d’énergie prévu le secteur résidentiel et les maisons passives. Un modèle mathématique basé sur des mesures expérimentales a été

La valorisation des rejets thermiques industriels par leur conversion en énergie mécanique, et éventuellement en électricité, est un moyen de réduire les émissions de gaz à effet de serre et de réduire la consommation énergétique des industries. La présente bourse de thèse est cofinancée par l’Agence De l’Environnement et de la Maitrise de l’Energie (ADEME) dans ce contexte. Le co-financeur de la thèse, Hevatech, est une entreprise qui exploite le brevet d’un nouveau convertisseur de chaleur en électricité appelé Turbosol®. Turbosol® est un bon candidat pour la valorisation de la chaleur fatal

La crise énergétique marquée par une flambée des prix du pétrole et les impératifs d’un développement durable font des énergies renouvelables une alternative qui suscitent aujourd'hui l’intérêt de plusieurs équipes de recherches. Le Sénégal, pays subsaharien, non producteur de pétrole n’est pas épargné par cette crise. Celle-ci se traduit par, une faible couverture du pays (en particulier les zones rurales) par le réseau électrique national. Pour faire face à cela, la nouvelle orientation en matière de politique énergétique met l’accent sur l’utilisation des énergies renouvelables notamment, l

Abstract:
The diploma thesis deals with the behavior of technical systems of the student dormitory in Brno. The temperature and humidity climate was measured and evaluated in the building. The measurement is then compared with the computer simulation created in DesignBuilder. The geometric model of the building was created in Revit, which supports BIM technology. Based on the evaluation of the experiment, the optimization of the technical systems in the building was proposed.

Une grande partie de la consommation d'énergie dans les bâtiments est due aux systèmes de chauffage, de ventilation et de climatisation. Entre autres systèmes, les systèmes de réfrigération font l'objet de mesures d'amélioration de l'efficacité. Néanmoins, les conditions opérationnelles réelles de ces installations et leurs performances doivent être connues, ainsi que tout potentiel d'optimisation éventuel, avant que des améliorations puissent être réalisées. Les analyses exergétique et énergétiques ont été largement utilisées pour évaluer la performance des systèmes de réfrigération. Entre au

Abstract:
The dissertation thesis is focused on the issue of energy recovery of waste. It contributes to optimization models developed in the author's workplace in the long term, which serve to simulate material flows in waste management and to search for an optimal waste management strategy. The main objective is to assess the potential for the use of heat produced in waste-to-energy plants as a key factor for the economy of these facilities. The thesis therefore represents an activity on the border of the fields of waste management and heating. Partial mathematical models were developed within the sco

This thesis is focused on identifying main factors influencing economical rentability of energy generated using incineration of municipal waste. Research was conducted focusing on municipal waste management, waste-to-energy possibilities and the issue of district heating systems, which are important considering the economy of waste-to-energy plants. Main limiting factors were identified using mathematic models adjusted for specific geographic locations.

Abstract:
Buildings are at the centre of our social and economic activity. Not only do we spend most of our lives in buildings, we also spend most of our money on buildings. The built environment is not only the largest industrial sector in economic terms, it is also the largest in terms of resource flow1. The rising energy costs, the growing concern about environmental issues and the approaching exhaustion of world energy resources are urging the entire European Community and the several national governments to improve energy management. Special attention is usually paid to public administrations
