Participatory Data Analysis: A New Method for Investigating Human Energy Practices
This paper presents a novel data-driven method to investigate the interdependence between technology design and human energy practices. The method – called Participatory Data – makes use of fine-grained energy data collected via smart meters and smart plugs, and behaviour visualisation during home visits to spark self-reflection among householders
Interactive Demand Shifting: in the Context of Emerging Energy Technologies
We are entering a key time period for home energy. While ubiquitous computing takes an increasing space in our daily life, emerging energy technologies including local generation and electric vehicle are leaving the stage of pioneer's users to become more common. This research highlights the potential of new energy behavior supported by digital tools in the context of domestic solar electricity generation
Demand response performance and uncertainty: A systematic literature review
The present review has been carried out, resorting to the PRISMA methodology, analyzing 218 published articles. A comprehensive analysis has been conducted regarding the consumer's role in the energy market. Moreover, the methods used to address demand response uncertainty and the strategies used to enhance performance and motivate participation have been reviewed. The authors find that participants will be willing to change their consumption pattern and behavior given that they have a complete awareness of the market environment, seeking the optimal decision. The authors also find that a contextual solution, giving the right signals according to the different behaviors and to the different types of participants in the DR event, can improve the performance of consumers' participation, providing a reliable response. DR is a mean of demand-side management, so both these concepts are addressed in the present paper. Finally, the pathways for future research are discussed.This article is a result of the project RETINA (NORTE-01-0145- FEDER-000062), supported by Norte Portugal Regional Operational Programme (NORTE 2020), under the PORTUGAL 2020 Partnership Agreement, through the European Regional Development Fund (ERDF).

Using Participatory Data Analysis to Understand Social Constraints and Opportunities of Electricity Demand-Shifting
International audienceThis paper reports results from an empirical study that explored the potential of interactive electricity Demand-Shifting – a particular form of behavior change where electricity consumption is shifted towards times of the day when production is at its highest – in the context of residential solar electricity generation. We conducted an in-the-wild user study with eighteen households over a period of six months, combining electricity data from smart meters and smart plugs with in-depth interviews to explore laundry routines and washing machine usage for each household. The study highlights that, although washing machines can be considered to be "shiftable appliances", the specific ways in which each household goes about shifting varies considerably. Furthermore, there is a clear need for ICTs to support people by analyzing current context and future plans to automate electricity demand-shifting and synchronization of both laundry and other appliances. Such support will help them maximize the self-consumption of micro-generated electricity while balancing this with environmental concerns, financial benefits and day-to-day issues relating to convenience.

Interactive Demand Shifting in the context of Domestic Micro-Generation
The combination of ubiquitous computing and emerging energy technologies is radically changing the home energy landscape. Domestic micro-generation, dominated by solar photovoltaic, is increasing at a rapid pace. This represents an opportunity for creating and altering energy behaviours. However, these transformations generate new challenges that we call the domestic energy gap: domestic electricity consumption and microgeneration are out of sync. Micro-generation is mainly uncontrollable production relying on weather while domestic energy consumption tends to happen mostly during the evening. This thesis focuses on understanding and supporting new domestic practices in the context of domestic solar electricity generation, looking at ‘Demand-Shifting’. Specifically, we look at how can digital tools leverage Demand-Shifting practices in the context of domestic micro-generation? Relying on a mixed-method approach, we provide a qualitative and quantitative answer with the collaboration of 38 participating households in several field studies including two spanning more than eight months. Through a deep investigation of laundry and electric mobility routines in the context of domestic micro-generation, we emphasised a natural engagement into Demand-Shifting which appeared as a complex and time-consuming task for participants which was not visible when we analysed their quantitative data. We revealed this complexity through Participatory Data Analyses, a method we designed to analyse the data in collaboration with the participating householders. This provided us with a comprehensive view of the relationship between domestic micro-generation and daily routines. Finally, we highlight the need for timely and contextual support through the deployment of interventions in-the-wild. Building on discussions of our findings in perspective of the literature, we propose a conceptual framework to support domestic interactive Demand-Shifting
Effective demand response gathering and deployment in smart grids for intensive renewable integration using aggregation and machine learning
Tesis por compendio de publicaciones.[EN] Distributed generation, namely renewables-based technologies, have
emerged as a crucial component in the transition to mitigate the effects of climate
change, providing a decentralized approach to electricity production. However,
the volatile behavior of distributed generation has created new challenges in
maintaining system balance and reliability. In this context, the demand response
concept and corresponding programs arise giving the local energy communities
prominence.
In demand response concept, it is expected an empowerment of the
consumer in the electricity sector. This has a significant impact on grid operations
and brings complex interactions due to the volatile behavior, privacy concerns,
and lack of consumer knowledge in the energy market context. For this,
aggregators play a crucial role addressing these challenges. It is crucial to develop
tools that allow the aggregators helping consumers to make informed decisions,
maximize the benefits of their flexibility resources, and contribute to the overall
success of grid operations. This thesis, through innovative solutions and
resorting to artificial intelligence models, addresses the integration of
renewables, promoting fair participation among all demand response providers.
The thesis ultimately results in an innovative decision support system -
MAESTRO, the Machine learning Assisted Energy System management Tool for
Renewable integration using demand respOnse. MAESTRO is composed by a set
of diversified models that together contribute for handling the complexity of
managing energy communities with distributed generation resources, demand
response providers, energy storage systems and electric vehicles.
This PhD thesis comprises a comprehensive analysis of state-of-the-art
techniques, system design and development, experimental results, and key
findings. In this research were published twenty-six scientific papers, in both
international journals and conference proceedings. Contributions to international
projects and Portuguese projects was accomplished.
[ES] La generación distribuida, en particular las tecnologías basadas en energías
renovables, se ha convertido en un componente crucial en la transición para
mitigar los efectos del cambio climático, al proporcionar un enfoque
descentralizado para la producción de electricidad. Sin embargo, el
comportamiento volátil de la generación distribuida ha generado nuevos
desafíos para mantener el equilibrio y la confiabilidad del sistema. En este
contexto, surge el concepto de respuesta de la demanda y los programas
correspondientes, otorgando prominencia a las comunidades energéticas locales.
En el concepto de "respuesta a la demanda" (DR por sus siglas en inglés), se
espera un empoderamiento del consumidor en el sector eléctrico. Esto tiene un
impacto significativo en la operación de la red y genera interacciones complejas
debido al comportamiento volátil, las preocupaciones de privacidad y la falta de
conocimiento del consumidor en el contexto del mercado energético. Para esto,
los agregadores desempeñan un papel crucial al abordar estos desafíos. Es
fundamental desarrollar herramientas que permitan a los agregadores ayudar a
los consumidores a tomar decisiones informadas, maximizar los beneficios de sus
recursos de flexibilidad y contribuir al éxito general de las operaciones de la red.
Esta tesis, a través de soluciones innovadoras y utilizando modelos de
inteligencia artificial, aborda la integración de energías renovables, promoviendo
una participación justa entre todos los proveedores de respuesta de la demanda.
La tesis resulta en última instancia en un sistema de apoyo a la toma de decisiones
innovador: MAESTRO, Machine learning Assisted Energy System management Tool
for Renewable integration using demand respOnse. MAESTRO está compuesto por
un conjunto de modelos diversificados que contribuyen juntos para manejar la
complejidad de la gestión de comunidades energéticas con recursos de
generación distribuida, proveedores de respuesta de la demanda, sistemas de
almacenamiento de energía y vehículos eléctricos.
