Abstract

La constante augmentation de la demande en électricité, l’arrivée de nouveaux usages électriques et l’intégration sans cesse plus importe d’énergies renouvelables a pour conséquence de rendre la gestion de l’adéquation entre la production et la demande d’électricité de plus en plus complexe. Les concepts de Smart Grids ou de Power-To-X tentent de trouver des solutions en rendant la demande plus flexible et en trouvant de nouvelles formes de stockage de l’électricité notamment au travers d’autres secteurs énergétiques. Plus particulièrement le but du Power-To-Heat est de stocker de l’électricité sous forme de chaleur par le moyen de pompes à chaleur et ce afin d’alimenter des réseaux de chaleurs ou de chauffer directement des bâtiments.&#13;La présente étude porte sur l’analyse de la flexibilité de la demande de chauffage d’un bâtiment résidentiel représentatif de la Région wallonne (RW). Nous avons étudié son comportement thermique dans le cadre d’une gestion de coupure de son système de chauffe par simulation dynamique dans le logiciel TRNSYS, et ce afin d’évaluer le possible déplacement des charges de chauffage de ce bâtiment. Différentes stratégies de coupures sous différentes variantes d’enveloppe, de ventilation et de masse thermique ont été analysées par le biais d’indicateurs énergétiques et de confort thermique.&#13;Les résultats pour les variantes d’isolation nous ont montré qu’il était possible de déplacer certaines charges liées à sa consommation de chauffage tout en limitant l’impact sur le confort thermique de l’occupant. Les variantes de ventilation ont montré d’importants problèmes d’inconfort thermique, la vitesse de chute de température étant bien plus importante dans le cadre d’une coupure de chauffage. Les variantes de masse thermique n’ont pas amélioré de façon significative la flexibilité du bâtiment ni en termes énergétiques, ni en termes de confort thermique. L’impact d’un parc de 2000 bâtiments tels que le bâtiment de référence étudié au niveau du réseau électrique peut sembler limité, surtout dans sa capacité à absorber des charges résiduelles.

Abstract

The heat storage based on thermochemical technology is associated with higher amounts of energy stored with respect to systems based on sensible heat. This interesting feature is stimulating the interest of the scientific community, among energy providers and grid managers, since it can effectively support the operation and integration of renewable high-efficiency systems and local smart grids. Research in this field is achieving unprecedented goals thanks to the profitable exploitation of results obtained in the field of heat pumps and thermally driven systems. The present issue offers the reader a sensational window to this rapidly evolving world.

Abstract

The penetration of distributed generation, energy storages and smart loads has resulted in the emergence of prosumers: entities capable of adjusting their electricity production and consumption in order to meet environmental goals and to participate profitably in the available electricity markets. Significant untapped potential remains in the exploitation and coordination of small and medium-sized distributed energy resources. However, such resources usually have a primary purpose, which imposes constraints on the exploitation of the resource; for example, the primary purpose of an electric vehicle battery is for driving, so the battery could be used as temporary storage for excess photovoltaic energy only if the vehicle is available for driving when the owner expects it to be. The aggregation of several distributed energy resources is a solution for coping with the unavailability of one resource. Solutions are needed for managing the electricity production and consumption characteristics of diverse distributed energy resources in order to obtain prosumers with more generic capabilities and services for electricity production, storage, and consumption. This collection of articles studies such prosumers and the emergence of prosumer communities. Demand response-capable smart loads, battery storages and photovoltaic generation resources are forecasted and optimized to ensure energy-efficient and, in some cases, profitable operation of the resources.

Abstract

This book focuses on the interaction between different energy vectors, that is, between electrical, thermal, gas, and transportation systems, with the purpose of optimizing the planning and operation of future energy systems. More and more renewable energy is integrated into the electrical system, and to optimize its usage and ensure that its full production can be hosted and utilized, the power system has to be controlled in a more flexible manner. In order not to overload the electrical distribution grids, the new large loads have to be controlled using demand response, perchance through a hierarchical control set-up where some controls are dependent on price signals from the spot and balancing markets. In addition, by performing local real-time control and coordination based on local voltage or system frequency measurements, the grid hosting limits are not violated.

Abstract

This Special Issue “Evaluation of Energy Efficiency and Flexibility in Smart Buildings” addresses the relevant role of buildings as strategic instruments to improve the efficiency and flexibility of the overall energy system. This role of the built environment is not yet fully developed and exploited and the book content contributes to increasing the general awareness of achievable benefits. In particular, different topics are discussed, such as optimal control, innovative efficient technologies, methodological approaches, and country analysis about energy efficiency and energy flexibility potential of the built environment. The Special Issue offers valuable insights into the most recent research developments worldwide.
