Appliance-Level Flexible Scheduling for Socio-Technical Smart Grid Optimization

Participation in residential energy demand response programs requires an active role by consumers. They contribute flexibility in how they use their appliances as the means to adjust energy consumption, and reduce demand peaks, possibly at the expense of their own comfort (e.g., thermal). Understanding the collective potential of appliance-level flexibility for reducing demand peaks is challenging and complex. For instance, physical characteristics of appliances, usage preferences, and comfort requirements all influence consumer flexibility, adoption, and effectiveness of demand response programs. To capture and study such socio-technical factors and trade-offs, this paper contributes a novel appliance-level flexible scheduling framework based on consumers' self-determined flexibility and comfort requirements. By utilizing this framework, this paper studies (i) consumers' usage preferences across various appliances, as well as their voluntary contribution of flexibility and willingness to sacrifice comfort for improving grid stability, (ii) impact of individual appliances on the collective goal of reducing demand peaks, and (iii) the effect of variable levels of flexibility, cooperation, and participation on the outcome of coordinated appliance scheduling. Experimental evaluation using a novel dataset collected via a smartphone app shows that higher consumer flexibility can significantly reduce demand peaks, with the oven having the highest system-wide potential for this. Overall, the cooperative approach allows for higher peak-shaving compared to non-cooperative schemes that focus entirely on the efficiency of individual appliances. The findings of this study can be used to design more cost-effective and granular (appliance-level) demand response programs in participatory and decentralized Smart Grids

A self-integration testbed for decentralized socio-technical systems

The Internet of Things (IoT) comes along with new challenges for experimenting, testing, and operating decentralized socio-technical systems at large-scale. In such systems, autonomous agents interact locally with their users, and remotely with other agents to make intelligent collective choices. Via these interactions they self-regulate the consumption and production of distributed (common) resources, e.g., self-management of traffic flows and power demand in Smart Cities. While such complex systems are often deployed and operated using centralized computing infrastructures, the socio-technical nature of these decentralized systems requires new value-sensitive design paradigms; empowering trust, transparency, and alignment with citizens’ social values, such as privacy preservation, autonomy, and fairness among citizens’ choices. Currently, instruments and tools to study such systems and guide the prototyping process from simulation, to live deployment, and ultimately to a robust operation of a high Technology Readiness Level (TRL) are missing, or not practical in this distributed socio-technical context. This paper bridges this gap by introducing a novel testbed architecture for decentralized socio-technical systems running on IoT. This new architecture is designed for a seamless reusability of (i) application-independent decentralized services by an IoT application, and (ii) different IoT applications by the same decentralized service. This dual self-integration promises IoT applications that are simpler to prototype, and can interoperate with decentralized services during runtime to self-integrate more complex functionality, e.g., data analytics, distributed artificial intelligence. Additionally, such integration provides stronger validation of IoT applications, and improves resource utilization, as computational resources are shared, thus cutting down deployment and operational costs. Pressure and crash tests during continuous operations of several weeks, with more than 80K network joining and leaving of agents, 2.4M parameter changes, and 100M communicated messages, confirm the robustness and practicality of the testbed architecture. This work promises new pathways for managing the prototyping and deployment complexity of decentralized socio-technical systems running on IoT, whose complexity has so far hindered the adoption of value-sensitive self-management approaches in Smart Cities

Barriers and Best Practices for the Circular Economy

Introduction We’re living in an exciting era. Rather than just another societal transition, we’re going through a fundamental societal transformation. Ecologist Joanne Macy calls this period ‘The Great Turning’: a period wherein we change from an industrial growth society into a life sustaining system’. Macy: “The most remarkable feature of this historical moment on Earth is not that we are on the way to destroying the world; we've actually been on the way for quite a while. It is that we are beginning to wake up, as from a millennia-long sleep, to a whole new relationship to our world, to ourselves and each other.” It is with these eyes that we have to see the rise of the Circular Economy. The Circular Economy is not just another trend in business; it’s the start of a completely new economic reality. The Circular Economy is the starting point for regenerative economics; for a new business-as-usual that - first and foremost - serves life and is based upon a fundamentally new value-paradigm. The future of success in business is about doing good for all stakeholders and creating benefit; not just profit. The Circular Economy demands next level thinking-and-doing in business, and there is no one more willing and able than the next generation of young professionals. It is therefore with great pride and pleasure that I present to you this publication of the SMO Promovendi. It offers fresh perspectives of a group of promising young scientists. All aspiring changemakers. It’s made with love and with the best of intentions; to help the Circular Economy forward

Appliance-level Flexible Scheduling for Socio-technical Smart Grid Optimisation

Participation in energy demand response programs requires an active role by users of residential appliances: they contribute flexibility in how they use their appliances as the means to adjust energy consumption and improve Smart Grid reliability. Understanding the collective potential that appliance-level flexibility has on Smart Grid reliability is challenging and complex. Physical characteristics of appliances, usage preferences, habits, and lifestyle are socio-technical factors that influence system-wide reliability coming often at the expense of users’ comfort, i.e. thermal. This paper studies appliance-level flexible scheduling and specifically the following research questions: (i) How flexible are users in scheduling their appliances to improve Smart Grid reliability? (ii) How do users’ comfort requirements affect the contributions of flexibility and as a result the collective action of improving Smart Grid reliability? (iii) Which appliances have the highest regulatory impact on Smart Grid? (iv) Can flexibility further improve Smart Grid reliability compared to simply operating individual appliances more efficiently? And finally, (v) what is the impact of varying users’ participation on the collective action of improving reliability? To address these questions, a distributed optimisation scheme is studied to coordinate the selection of multiple appliance-level schedules representing users’ self-determined flexibility. Experimental evaluation using a novel dataset collected via a smartphone app shows that higher user flexibility significantly improves Smart Grid reliability with the oven having the highest system-wide potential for this. Compared to an existing efficiency scheme for kettles, flexible coordinated scheduling shows further improvements in reliability. These new findings have implications for the design of more cost-effective and granular demand response programs in participatory and decentralised Smart Grids

Ethics of Smart Cities: Towards Value-Sensitive Design and Co-Evolving City Life

The digital revolution has brought about many societal changes such as the creation of “smart cities”. The smart city concept has changed the urban ecosystem by embedding digital technologies in the city fabric to enhance the quality of life of its inhabitants. However, it has also led to some pressing issues and challenges related to data, privacy, ethics inclusion, and fairness. While the initial concept of smart cities was largely technology- and data-driven, focused on the automation of traffic, logistics and processes, this concept is currently being replaced by technology-enabled, human-centred solutions. However, this is not the end of the development, as there is now a big trend towards “design for values”. In this paper, we point out how a value-sensitive design approach could promote a more sustainable pathway of cities that better serves people and nature. Such “value-sensitive design” will have to take ethics, law and culture on board. We discuss how organising the digital world in a participatory way, as well as leveraging the concepts of self-organisation, self-regulation, and self-control, would foster synergy effects and thereby help to leverage a sustainable technological revolution on a global scale. Furthermore, a “democracy by design” approach could also promote resilience.ISSN:2071-105
