| Summary/Abstract |
The digitalization of the electricity grid opens the way to bundle value added services to the electricity commodity, and possibly shift business value to electricity services in line with the notions of efficiency, conservation and sustainability. In this context, market forces should be mobilized within the boundaries of energy policy goals to contribute to the massive investments that are required to fulfill the Smart Grid vision. In this paper, we present a systemic perspective aimed at establishing technical and economic synergies that may improve the business cases of individual different Smart Grid technologies and contribute to reverse the consumption-driven paradigm of the electricity sector. Our analysis is supported by evidence from applications in the electric vehicle and smart meter ecosystems. Throughout the paper, an EU (European Union) perspective is primarily considered.

| Summary/Abstract |
Climate emergency has changed the way of supplying energy, replacing fossil fuels in favour of a transition to renewable sources crucial for the system decarbonization. This change has led to a review of the electricity consumption and distribution model. Recently end-users connected to distribution grids have taken an increasing active role in the electrical power system. Such a situation highlights how the combination between distributed generation-active user, through the concept of energy self-consumption that turns in energy sharing for a ‘collective’ form, allowed by virtual self-consumption, seems to be a good solution to achieve both climate targets and solve technical issues related to renewables penetration. Aggregation of end-users which produce and self-consume their energy within the same geographical perimeter express a new way to use renewable energy represented by the energy communities. The paper identifies the key elements that effect a business model for energy sharing by residential end-users equipped with small-scale renewable generation plants. In addition the simulation analysis investigate the feasibility from the aggregator point of view as well as the individual end-users evaluating also a minimum size for a viable renewable energy community.

| Summary/Abstract |
In recent years, the increasing popularity of renewable energy and energy-efficient technologies is creating a new movement towards more sustainable communities. Understanding energy consumption is important for the optimisation of resources and the implementation of ecological trends. This paper integrates electricity consumers into a cooperative framework for planning sustainable smart communities through aggregators, which reallocates consumers’ demand according to available renewable energy supply collected from consumers and service providers. The aggregated demand response also includes consumers involved in energy production activities through microgeneration capabilities. A characterisation study of the different types of demand preferences is performed by defining scenarios of communities and consumers’ behaviours, which are validated through a reputation factor. The results show that the system adequately manages demand reallocation following the preferences and contribution of consumers and/or prosumers. Besides, this research analyses the current energy policy concerning demand flexibility, demand aggregation and microgeneration capacity, and their regulations in Spain. Finally, microgeneration acceptance, the role of aggregators and prosumers in the scheduling process is also investigated through a series of surveys.
