Pricing and sharing rules for energy communities

Abstract

Prosumers and consumers can form together a renewable energy community. The community purchases the production surplus from prosumers and resells it to members and energy retailers. Members buy electricity at a discount compared to the retail price, and prosumers sell their electricity at a premium compared to the market price. The community determines these internal prices and establishes a sharing rule to allocate collective self-consumption among its members. In this paper, we analyze the roles of prices and sharing rules in identifying feasible communities and the resulting allocation of surplus among members. We illustrate our results with a numerical simulation.
