With the deregulation and urgent necessity of decarbonizing electricity sector, end users have been empowered to actively partake in operation system. In this context, energy communities arise as a regulatory framework that allows aggregating group domestic consumers (or prosumers) order share own resources such storage or photovoltaics. However, collective assets should be properly designed exploit them an optimal way well avoid oversizing components, which may result higher expenditures economically harmful. This new paradigm calls for developing proper computational tools optimally planning operating communities. paper, novel tool photovoltaic arrays cooperative is developed. problem encompasses continuous binary variables, are evaluated over long time horizons characterized through representative sets.
