Analysing Energy Allocation in Renewable Energy Communities: A Hybrid Static-Dynamic model

Abstract. The current global energy landscape is facing numerous challenges as electricity demand progressively surges: the urgent need to decarbonize generation, the increasing strain on aging transmission infrastructures, and the complex integration of intermittent renewable resources. In this scenario, Renewable Energy Communities (REC) are emerging as promising assets to achieve energy security and face increasing electricity prices. However, as RECs are still developing, there is a lack of a standardized applicable framework for the allocation of the benefits derived from self-consumption. In this work, a hybrid allocation model is developed to distribute the benefits among members of a REC based on two main pillars: type of ownership and electricity demand. The model is designed to be tailored to the own interests of the community: social equity, return on investment or self consumption, among others. Through simulations on a mathematical model, it is verified that the final annual cost of electricity is lower than the baseline standard framework for REC.
