    Energy storage can play a crucial role in decarbonising power systems by balancing power and energy in time. Wider power system benefits that arise from these balancing technologies include lower grid expansion, renewable curtailment, and average electricity costs. However, with the proliferation of new energy storage technologies, it becomes increasingly difficult to identify which technologies are economically viable and how to design and integrate them effectively. Using large-scale energy system models in Europe, the dissertation shows that solely relying on Levelized Cost of Storage (LCOS) metrics for technology assessments can mislead and that traditional system-value methods raise important questions about how to assess multiple energy storage technologies. Further, the work introduces a new complementary system-value assessment method called the market-potential method, which provides a systematic deployment analysis for assessing multiple storage technologies under competition. However, integrating energy storage in system models can lead to the unintended storage cycling effect, which occurs in approximately two-thirds of models and significantly distorts results. The thesis finds that traditional approaches to deal with the issue, such as multi-stage optimization or mixed integer linear programming approaches, are either ineffective or computationally inefficient. A new approach is suggested that only requires appropriate model parameterization with variable costs while keeping the model convex to reduce the risk of misleading results. In addition, to enable energy storage assessments and energy system research around the world, the thesis extended the geographical scope of an existing European opensource model to global coverage. The new build energy system model ‘PyPSA-Earth’ is thereby demonstrated and validated in Africa. Using PyPSA-Earth, the thesis assesses for the first time the system value of 20 energy storage technologies across multiple scenarios in a representative future power system in Africa. The results offer insights into approaches for assessing multiple energy storage technologies under competition in large-scale energy system models. In particular, the dissertation addresses extreme cost uncertainty through a comprehensive scenario tree and finds that, apart from lithium and hydrogen, only seven energy storage are optimizationrelevant technologies. The work also discovers that a heterogeneous storage design can increase power system benefits and that some energy storage are more important than others. Finally, in contrast to traditional methods that only consider single energy storage, the thesis finds that optimizing multiple energy storage options tends to significantly reduce total system costs by up to 29%. The presented research findings have the potential to inform decision-making processes for the sizing, integration, and deployment of energy storage systems in decarbonized power systems, contributing to a paradigm shift in scientific methodology and advancing efforts towards a sustainable future

    PlayMaps - Representation of 3D cartography data in Augmented Reality (AR) games

    Get PDF
    A presente dissertação tem como tema a representação de dados cartográficos 3D em ambientes de Realidade Aumentada (RA) aplicados a tecnologias móveis. No turismo, a escolha de um lugar para visitar pode ser um processo árduo e exaustivo que na maioria das vezes traz contratempos imprevistos. Dada a abundância de informações sobre um local, ou mesmo a falta dela em muitas circunstâncias, é simples para um possível turista ficar desorientado e fazer o julgamento incorreto de não visitá-lo. Em muitos casos, as pessoas até desconhecem o potencial das regiões. Muitos representantes têm lutado para encontrar maneiras de atrair mais turistas para suas cidades, muitas vezes se perguntando: "Como posso promover minha cidade para o mundo de uma maneira mais eficaz?". Obviamente, essa divulgação precisa ser feita de forma segura e acessível. Assim, esta dissertação pretende criar um jogo para adolescentes, entre os 10 e os 15 anos, baseado em Realidade Aumentada (RA), que seja capaz de digitalizar um mapa em papel e permitir ao utilizador interagir com o mesmo. A app terá de proporcionar a componente educativa do território e também um nível adequado de interação com o utilizador. Este aplicativo será fácil de usar e compatível com qualquer sistema operacional móvel. Como tal, foi pensado para que qualquer pessoa com um smartphone possa utilizar esta tecnologia. Além disso, este aplicativo será flexível, adaptável e genérico. Cartografias diferentes exigirão modelos geográficos diferentes ou mesmo metodologias de jogo diferentes. Portanto, este aplicativo terá a capacidade de importar diferentes informações geográficas e criar um jogo específico para essa cartografia. Dois estudos anteriores foram realizados nesta área, nomeadamente para potenciar a experiência de visitas à Galeria da Biodiversidade e ao Jardim Botânico como forma de jogo. O primeiro estudo utiliza o método "case study", utilizando uma abordagem quantitativa e qualitativa para entender como a experiência lúdica proporcionada pela tecnologia de realidade aumentada pode contribuir para a entrega de informações que esses espaços pretendem transmitir aos visitantes {soares2021flo}. O segundo estudo procurou explorar formas de conectar ambientes internos e externos por meio de Realidade Aumentada (RA) {teixeira2021serious}. Esses tipos de abordagens de como disseminar informações são fundamentais para que o usuário tenha uma compreensão adequada do que a região tem a oferecer. Esses recursos serão aplicados ao mapeamento de territórios conhecidos a fim de investigar formas de promover o turismo melhorando e inovando a forma como as pessoas aprendem e exploram novas cidades e outros espaços. Embora esta dissertação seja apenas um caso de estudo, com esta implementação, a solução proposta pode funcionar como base para o desenvolvimento de uma ferramenta universal para qualquer instituição e/ou cidade que se queira promover.The present dissertation has, as its theme, the representation of 3D cartography data in Augmented Reality (AR) environments applied to mobile technologies. In tourism, choosing a place to visit can be a hard and exhaustive process which most times brings unforeseen setbacks. Given the abundance of information about a location, or even the lack thereof in many circumstances, it's simple for a possible tourist to become disoriented and make the incorrect judgement of not visiting it. In many cases, people even are unaware of the regions' potential. Many city officials and space marketers have struggled to find ways to attract more tourists to their cities, often asking themselves, "How can I promote my city to the world in a more effective way?". Obviously, this advertisement needs to be done in a safe and affordable way. Therefore, this dissertation aims to create a game for teens, between 10 and 15 years old, based on Augmented Reality (AR), which is capable to digitise a paper map and allowing the user to interact with it. The app will have to provide the educational component of the territory and also an appropriate level of interaction with the user. This app will be easy to use, user-friendly and compatible with any mobile operating system. As such, it is designed that anyone with a smart phone can use this technology. Furthermore, this app will be flexible, adaptable and generic. Different cartographies will require different geographical models or even different game methodologies. Therefore, this application will have the ability to import different geographic information, and create a specific game to that cartography. Two previous studies were carried out in this area, namely to enhance the experience of visits to Galeria da Biodiversidade and Jardim Botânico as a form of a game. The first study employs the case study method, using a quantitative and qualitative approach to comprehend how the entertaining experience given by augmented reality technology may contribute in the delivery of the information these spaces intend to transmit to visitors {soares2021flo}. The second study sought to explore ways to connect indoor and outdoor environments through Augmented Reality (AR) {teixeira2021serious}. These types of approaches on how to disseminate information are fundamental for the user to have an appropriate grasp of what the region has to offer. These functionalities will be applied to cartography of know territories in order to investigate ways to promote tourism by improving and innovating the way people learn and explore new cities and other spaces. Although this dissertation is only a case study, with this implementation, the proposed solution can become a stepping stone to the development of a universal tool for any institution and/or city that intends to promote itself

    A conceptual framework for developing dashboards for big mobility data

    Full text link
    Dashboards are an increasingly popular form of data visualization. Large, complex, and dynamic mobility data present a number of challenges in dashboard design. The overall aim for dashboard design is to improve information communication and decision making, though big mobility data in particular require considering privacy alongside size and complexity. Taking these issues into account, a gap remains between wrangling mobility data and developing meaningful dashboard output. Therefore, there is a need for a framework that bridges this gap to support the mobility dashboard development and design process. In this paper we outline a conceptual framework for mobility data dashboards that provides guidance for the development process while considering mobility data structure, volume, complexity, varied application contexts, and privacy constraints. We illustrate the proposed framework’s components and process using example mobility dashboards with varied inputs, end-users and objectives. Overall, the framework offers a basis for developers to understand how informational displays of big mobility data are determined by end-user needs as well as the types of data selection, transformation, and display available to particular mobility datasets

    Blending the Material and Digital World for Hybrid Interfaces

    The development of digital technologies in the 21st century is progressing continuously and new device classes such as tablets, smartphones or smartwatches are finding their way into our everyday lives. However, this development also poses problems, as these prevailing touch and gestural interfaces often lack tangibility, take little account of haptic qualities and therefore require full attention from their users. Compared to traditional tools and analog interfaces, the human skills to experience and manipulate material in its natural environment and context remain unexploited. To combine the best of both, a key question is how it is possible to blend the material world and digital world to design and realize novel hybrid interfaces in a meaningful way. Research on Tangible User Interfaces (TUIs) investigates the coupling between physical objects and virtual data. In contrast, hybrid interfaces, which specifically aim to digitally enrich analog artifacts of everyday work, have not yet been sufficiently researched and systematically discussed. Therefore, this doctoral thesis rethinks how user interfaces can provide useful digital functionality while maintaining their physical properties and familiar patterns of use in the real world. However, the development of such hybrid interfaces raises overarching research questions about the design: Which kind of physical interfaces are worth exploring? What type of digital enhancement will improve existing interfaces? How can hybrid interfaces retain their physical properties while enabling new digital functions? What are suitable methods to explore different design? And how to support technology-enthusiast users in prototyping? For a systematic investigation, the thesis builds on a design-oriented, exploratory and iterative development process using digital fabrication methods and novel materials. As a main contribution, four specific research projects are presented that apply and discuss different visual and interactive augmentation principles along real-world applications. The applications range from digitally-enhanced paper, interactive cords over visual watch strap extensions to novel prototyping tools for smart garments. While almost all of them integrate visual feedback and haptic input, none of them are built on rigid, rectangular pixel screens or use standard input modalities, as they all aim to reveal new design approaches. The dissertation shows how valuable it can be to rethink familiar, analog applications while thoughtfully extending them digitally. Finally, this thesis’ extensive work of engineering versatile research platforms is accompanied by overarching conceptual work, user evaluations and technical experiments, as well as literature reviews.Die Durchdringung digitaler Technologien im 21. Jahrhundert schreitet stetig voran und neue Geräteklassen wie Tablets, Smartphones oder Smartwatches erobern unseren Alltag. Diese Entwicklung birgt aber auch Probleme, denn die vorherrschenden berührungsempfindlichen Oberflächen berücksichtigen kaum haptische Qualitäten und erfordern daher die volle Aufmerksamkeit ihrer Nutzer:innen. Im Vergleich zu traditionellen Werkzeugen und analogen Schnittstellen bleiben die menschlichen Fähigkeiten ungenutzt, die Umwelt mit allen Sinnen zu begreifen und wahrzunehmen. Um das Beste aus beiden Welten zu vereinen, stellt sich daher die Frage, wie neuartige hybride Schnittstellen sinnvoll gestaltet und realisiert werden können, um die materielle und die digitale Welt zu verschmelzen. In der Forschung zu Tangible User Interfaces (TUIs) wird die Verbindung zwischen physischen Objekten und virtuellen Daten untersucht. Noch nicht ausreichend erforscht wurden hingegen hybride Schnittstellen, die speziell darauf abzielen, physische Gegenstände des Alltags digital zu erweitern und anhand geeigneter Designparameter und Entwurfsräume systematisch zu untersuchen. In dieser Dissertation wird daher untersucht, wie Materialität und Digitalität nahtlos ineinander übergehen können. Es soll erforscht werden, wie künftige Benutzungsschnittstellen nützliche digitale Funktionen bereitstellen können, ohne ihre physischen Eigenschaften und vertrauten Nutzungsmuster in der realen Welt zu verlieren. Die Entwicklung solcher hybriden Ansätze wirft jedoch übergreifende Forschungsfragen zum Design auf: Welche Arten von physischen Schnittstellen sind es wert, betrachtet zu werden? Welche Art von digitaler Erweiterung verbessert das Bestehende? Wie können hybride Konzepte ihre physischen Eigenschaften beibehalten und gleichzeitig neue digitale Funktionen ermöglichen? Was sind geeignete Methoden, um verschiedene Designs zu erforschen? Wie kann man Technologiebegeisterte bei der Erstellung von Prototypen unterstützen? Für eine systematische Untersuchung stützt sich die Arbeit auf einen designorientierten, explorativen und iterativen Entwicklungsprozess unter Verwendung digitaler Fabrikationsmethoden und neuartiger Materialien. Im Hauptteil werden vier Forschungsprojekte vorgestellt, die verschiedene visuelle und interaktive Prinzipien entlang realer Anwendungen diskutieren. Die Szenarien reichen von digital angereichertem Papier, interaktiven Kordeln über visuelle Erweiterungen von Uhrarmbändern bis hin zu neuartigen Prototyping-Tools für intelligente Kleidungsstücke. Um neue Designansätze aufzuzeigen, integrieren nahezu alle visuelles Feedback und haptische Eingaben, um Alternativen zu Standard-Eingabemodalitäten auf starren Pixelbildschirmen zu schaffen. Die Dissertation hat gezeigt, wie wertvoll es sein kann, bekannte, analoge Anwendungen zu überdenken und sie dabei gleichzeitig mit Bedacht digital zu erweitern. Dabei umfasst die vorliegende Arbeit sowohl realisierte technische Forschungsplattformen als auch übergreifende konzeptionelle Arbeiten, Nutzerstudien und technische Experimente sowie die Analyse existierender Forschungsarbeiten
