标题： Fairness of Energy Distribution Mechanisms in Collective Self-Consumption Schemes

摘要： 在几个欧洲国家，监管框架现在允许家庭组建能源社区并通过本地能源市场（LEMs）进行本地能源交易。 尽管存在多种机制来在成员之间分配本地生产的能源，但其公平性仍不够明确，尽管能源正义是社区的一个关键关注点。 本文首先对法国的集体自用电过程进行了详尽的描述，为研究人员提供了一个现实世界的框架。 我们随后回顾了与LEMs相关的主要公平类型，并为每种类型确定了适当的指标，包括一个用于评估功绩公平性的新可扩展指标。 通过在250个随机生成的20户住宅社区中进行模拟，我们评估并比较了不同LEMs分配机制的公平性。 结果表明，当光伏采用率达到40%时，平均财务节省可达12%。 在评估的四种广泛使用的LEMs机制中，优先级填充方法在平等和最小最大公平性方面表现最佳。 双拍卖和按比例方案促进了功绩主义，而标准的填充方法在公平目标之间提供了强大的平衡。 显示英文摘要

摘要： In several European countries, regulatory frameworks now allow households to form energy communities and trade energy locally via local energy markets (LEMs). While multiple mechanisms exist to allocate locally produced energy among members, their fairness remains insufficiently understood despite energy justice being a key concern for communities. This paper first provides a thorough description of the collective self-consumption process in France, offering a real world framework for researchers. We then review the main types of fairness relevant to LEMs and identify appropriate indicators for each, including a new scalable indicator to evaluate meritocratic fairness. Using simulations across 250 randomly generated residential communities of 20 households, we assess and compare fairness across different LEM distribution mechanisms. Results show that average financial savings reach 12% with 40% PV uptake. Among the four widely used LEM mechanisms assessed, glass-filling with prioritization yields the highest egalitarian and min max fairness. Double auction and pro rata schemes promote meritocracy, while standard glass filling offers a strong balance across fairness objectives.
