Abstract

This study employs a Mixed-Integer Linear Programming model to optimize energy transactions in a decentralized energy community. Through grid and peer-to-peer transactions, this research promotes energy sharing. Incorporating energy storage systems, the study integrates fairness metrics to evaluate economic equity. The case study, considering households with different equipment acquisition power, reveals the impact of pricing structures on economic fairness. Analyzing optimal results, the study focused on a community of ten households, six of which are prosumers with PV and energy storage of different levels. Results show that combining peer-to-peer transactions and different levels of PV and storage yields up to a 153% improvement in energy bills. On the other hand, members participating in energy sharing without PV and storage within the community only achieve ~3% improvement in their energy bill, clearly showing a disparity in cost savings linked to equipment capacity acquisition.
