鉴于可再生能源发电、储能和电动汽车充电等新负荷的广泛采用，人们越来越努力提高当地的能源弹性，特别是在社区一级。这导致人们对发展地方或社区能源项目越来越感兴趣，在这些项目中，个人生产消费者能够在社区内生产、储存和交易能源，从而使市场力量从大型公用事业公司转移到个人生产消费者。这种计划通常涉及一群消费者投资于社区拥有的资产，如社区拥有的风力涡轮机或共享电池存储。然而，开发方法，使有效的控制和公平分享共同拥有的资产是一个关键的开放问题，研究和实践的重要性。在本文中，我们提供了一种方法，从博弈论概念的启发，公平地重新分配社区拥有的能源资产，如社区风力涡轮机和存储的利益。我们提出了一种基于神经网络的电池控制算法，最大化背后的米自我消耗，它考虑了电池寿命退化的影响。我们使用真实的消费和生产数据对一个200户家庭的社区进行建模，评估和比较投资于个人拥有或社区拥有的资产（如化学品储存）的技术和经济效益。我们表明，电池存储简单的投资回收期可以大大减少共享社区内的资产。最后，我们比较了几个社区拥有的资产的再分配和利益分配方案，并表明，所提出的方案的基础上，从合作博弈论的原则，实现了最公平的再分配。
Given the widespread adoption of renewable generation, storage and new loads like electric vehicle charging, there has been a growing effort to enhance local energy resilience, particularly at the community level. This has led to increasing interest in the development of local or community energy projects, in which individual prosumers are able to generate, store and trade energy within the community — enabling a shift in market power from large utility companies to individual prosumers. Such schemes often involve a group of consumers investing in community-owned asset such as community-owned wind turbines or shared battery storage. Yet, developing methods to enable efficient control and fair sharing of jointly-owned assets is a key open question, of both research and practical importance. In this paper, we provide a method inspired from game theory concepts to fairly redistribute the benefits from community owned energy-assets such as community wind turbines and storage. We propose a heuristic-based battery control algorithm for maximization of behind-the-meter self-consumption, which considers the effect of battery life degradation. Using real consumption and production data to model a community of two hundred households, we assess and compare technical and economic benefits of investment in individually-owned or community-owned assets such as chemical storage. We show that battery storage simple pay-back period can be considerably reduced by sharing the asset within a community. Finally, we compare several redistribution and benefit allocation schemes for community-owned assets, and show that the proposed scheme based on principles from cooperative game theory achieves the fairest redistribution.
