“…The profitability of PV electricity sharing was investigated with respect to the situations in different European countries [25], as well as in the specific light of the newly implemented legislation in Austria [26]. The application of different electricity distribution keys in ECs, which have a significant impact on their economic viability, was addressed in [20,27]. Focusing on net-zero ECs, Isaac et al [28] studied cost optimality while considering different urban scales and densities.…”

The aim of this study is to provide insights regarding the economic viability of and energy flows within a renewable energy community based on a linear optimisation model with peer-to-peer electricity trading. Different technologies, such as PV, heat pumps, electric vehicles, and a community battery storage, are modelled. With the objective of achieving a cost-optimal solution for the whole community, the individual impacts of different technologies, as well as their permutations, are investigated. Therefrom, financial and environmental advantages and disadvantages for individual participants and the whole community can be derived. The results indicate that customers who are equipped with a combination of PV systems, heat pumps, and EVs achieve better individual results compared to those with lower levels of technology. Especially when heat pumps are involved, the amounts of PV electricity generated can be used with high efficiency, increasing the benefits of energy community participation. Moreover, the higher the level of electricity-based technologies within the community is, the lower the conventional grid feed-in becomes. An additional implementation of a community battery storage can further reduce these amounts and, thus, the grid burden. Apart from the financial benefits, the installation of additional assets and, thus, reduced grid feed-in contribute to the reduction of CO2-emissions. This study’s results can aid in making decisions regarding investments and energy community composition, as well as in the funding decisions of policymakers.

“…The methods that can be found in the literature for modeling the distribution of energy and costs within the community are diverse. Many authors rely on optimization methods [25][26][27][28] and load scheduling, but simulation models [29] also have a presence in recent studies. Moreover, the dynamic allocation keys introduced under the new regulation open up a range of possibilities for a more efficient energy allocation.…”

Collective self-consumption (CSC) systems offer a great opportunity to increase the viability of photovoltaic installations by reducing costs and increasing profitability for consumers. In addition, CSC systems increase self-sufficiency (SS) and self-consumption (SC). These systems require a proper energy allocation strategy (EAS) to define the energy distribution within the CSC. However, most EASs do not analyze the individual impact of the rules and mechanisms adopted. Therefore, six different EASs are proposed and evaluated in terms of both collective and individual cost, SC, and SS. The results show that the EASs based on minimizing collective costs are the most beneficial for the community, although they imply an unfair distribution of energy among users. On the other hand, the other EASs proposed stand out for reaching an equilibrium in terms of cost, SS, and SC, although the collective profitability is lower. The best results are achieved considering dynamic coefficients, which are preferred over static ones.
