RT Conference Proceedings T1 Sharing-Cost Factors for a Community of PV Prosumers with Battery Storage A1 Barba Marcos, Jorge A1 Martín-Rivas, Sebastián K1 Instalaciones fotovoltaicas K1 Redes de energía eléctrica inteligentes AB The aggregation of prosumers into energy communities brings multiple benefits in terms of use of the PV and reducing costs. However, it is also a challenge to determine the sharing cost (installation and operation) for each user. The main contribution of this work is a cost-sharing rule based on the influence that each prosumer has on the total cost of the community. In addition, the proposed sharing factors allow to determine in which equipment of the installation (PV, Battery, Grid connection) is more beneficial for the user to participate. The proposed sharing factors are illustrated on an energy community with ten users under different market energy prices and PV, battery costs. As a main conclusion, it is confirmed that taking part in an energy community is beneficial in terms of total (amortization + operation) savings for each participant.
