This paper introduces a methodology to perform an ex-post allocation of locally generated electricity among the members of a renewable energy community. Such an ex-post allocation takes place in a settlement phase where the financial exchanges of the community are based on the production and consumption profiles of each member. The proposed methodology consists of an optimisation framework which (i) minimises the sum of individual electricity costs of the community members, and (ii) can enforce minimum self-sufficiency rates --proportion of electricity consumption covered by local production-- on each member, enhancing the economic gains of some of them. The latter capability aims to ensure that members receive enough incentives to participate in the renewable energy community. This framework is designed so as to provide a practical approach that is ready to use by community managers, which is compliant with current legislation on renewable energy communities. It computes a set of optimal repartition keys, which represent the percentage of total local production given to each member -- one key per metering period per member. These keys are computed based on an initial set of keys provided in the simulation, which are typically contractual i.e., agreed upon between the member and the manager the renewable energy community. This methodology is tested in a broad range of scenarios, illustrating its ability to optimise the operational costs of a renewable energy community.

可再生能源社区本地发电的分配

本文介绍了一种在可再生能源社区成员之间对本地发电进行事后分配的方法。这种事后分配发生在结算阶段，社区的金融交易基于每个成员的生产和消费情况。提议的方法包括一个优化框架，它 (i) 最小化社区成员的个人电力成本总和，以及 (ii) 可以对每个成员强制执行最低自给率——当地生产所涵盖的电力消耗的比例—— ，提高其中一些的经济收益。后一种能力旨在确保成员获得足够的激励来参与可再生能源社区。该框架旨在提供一种可供社区管理者使用的实用方法，该方法符合当前关于可再生能源社区的立法。它计算一组最佳重新分区键，这些键表示分配给每个成员的本地总产量的百分比——每个成员每个计量周期一个键。这些密钥是基于模拟中提供的一组初始密钥来计算的，这些密钥通常是契约性的，即在成员和可再生能源社区的管理者之间达成一致。该方法在广泛的场景中进行了测试，说明了其优化可再生能源社区运营成本的能力。它计算一组最佳重新分区键，这些键表示分配给每个成员的本地总产量的百分比——每个成员每个计量周期一个键。这些密钥是基于模拟中提供的一组初始密钥来计算的，这些密钥通常是契约性的，即在成员和可再生能源社区的管理者之间达成一致。该方法在广泛的场景中进行了测试，说明了其优化可再生能源社区运营成本的能力。它计算一组最佳重新分区键，这些键表示分配给每个成员的本地总产量的百分比——每个成员每个计量周期一个键。这些密钥是基于模拟中提供的一组初始密钥来计算的，这些密钥通常是契约性的，即在成员和可再生能源社区的管理者之间达成一致。该方法在广泛的场景中进行了测试，说明了其优化可再生能源社区运营成本的能力。
