Exploring Energy Flexibility in Renewable Energy Communities

Publication . Queiroz, Humberto Almeida de; Martins, João; Lopes, Rui

To avoid the worst effects of climate change, there must be a paradigm shift in the way energy is converted, transported, distributed, and consumed. More specifically, there should be a change from the current state, where supply always follows demand, to a new state, where demand is also adjusted instantly to the supply level. In this context, energy flexibility repre- sents an important tool to adapt consumption to the different generation conditions, assuming particular interest in the integration of distributed energy generation systems, based on re- newable sources, in an energy transition towards sustainability. In addition, energy flexibility will be fundamental in solving the challenges imposed by the increasing electrification of so- ciety's processes (e.g., introduction of electric vehicles), which highlights the additional bur- den imposed on energy systems, and the joint effort of society to mitigate changes with the limitation of greenhouse gas emissions. In this context, the contribution of this Doctoral thesis is threefold: firstly, based on a literature review on demand energy flexibility, a novel characterization of the energy flexibil- ity potential of event-based devices is proposed, considering the Portuguese legislation on the operation of renewable energy communities. The second contribution of this study is to pro- pose a new framework to support the management of renewable energy communities, namely the energy sharing process. Lastly, the energy flexibility potential of selected event-based de- vices is explored in a case study to increase the benefits of energy consumers and prosumers and to assess the impact of energy flexibility on energy sharing strategies in renewable energy communities.
