| Sumario: | Effective deployment of Renewable Energy Communities (RECs) is essential for the success of Europe’s energy transition. However, there are no clear criteria for sharing energy generation among community members, which conditions the rhythm of RECs penetration. The lack of transversal legislation gave rise to different approaches in EU countries for solving this issue, with the calculation of ‘a priori’ and ‘a posteriori’ energy sharing coefficients being the most extended ones. Nevertheless, it is still necessary to develop better optimization algorithms to make the most of RECs, to minimize the surplus of energy, and improve payback among end-users and their impact on the energy system. This paper gives an overview of the state-of-the-art and proposes improvements to the linear programming (LP) methodologies devoted to obtaining an optimal calculation of renewable sharing coefficients; able to provide satisfactory results, no matter the size of the REC, while consuming affordable computation resources. The performance of the proposed method has been validated using real generation and consumption data collected from a Spanish DSO, considering both ‘a priori’ and ‘a posteriori’ remuneration schemes. The results prove the good behaviour of the proposed solution for different REC sizes and operating conditions. |
