Electricity Distribution Among Users of an Energy Community: Calculation of Repartition Coefficients Under Social Scenarios

Abstract

Current Spanish regulation allows the calculation of repartition coefficients to distribute electricity to users of an energy community. Literature has focused on minimum-cost solutions, and has paid less attention to the introduction of social objectives (e.g., equity) and constraints (e.g., due to the presence of users in a vulnerable situation). This paper studies the definition of dynamic repartition coefficients under different social scenarios by means of a mixed-integer linear programming model. Results for an illustrative case study show how the same cost per energy unit for all users can be obtained, to promote equity, or how a reduced price can be achieved for vulnerable users. Such results can assist energy communities’ promoters with the definition of the every-day electricity sharing among users.
