Scientific Background and Project Context:

The energy transition is bringing about profound changes in energy systems, with the massive deployment of renewable energy and an increasing role for electricity in this new environment. Access to energy is currently largely managed through centralized dispatch. Grid operators are heavily involved in this new management framework, particularly regarding flexibility and balancing. However, decentralization is disrupting their previous organizational structure, and they must adapt to this new and uncertain environment, which consists of distributed energy resources, storage, flexibility requirements, and the coordination of backup technologies. It is therefore necessary to rethink the economic model and behavioral organization, both for certain distribution stakeholders (suppliers and consumers) and for grid and market operators. Grid reliability will continue to depend on this new economic organization and on investments to make the distribution grid (and the distribution system operator) more active in downstream and decentralized markets.

In the coming years, further research will be needed to examine how the trading mechanisms of community energy systems influence the centralized electricity market and the grid system, as well as the associated changes in the revenues and rates of participating stakeholders (Abada et al., 2020a, 2020b). It is therefore crucial to analyze the impact of different tariff models and potential barriers to further integration of energy communities into the electricity grid and markets, in order to ensure their successful deployment and optimal cost allocation (Capper et al., 2022; Casalicchio et al., 2021; Li et al., 2021). This study aims to address this gap in the context of the energy transition.
