The new concept of renewable energy communities introduced by the Revised European Directive on the promotion of renewable sources (2018/2001) has opened new possibilities for microgrids. In fact, it permits to enhance the value of the energy produced by renewable sources sharing it inside an “energy community” and to increase the social welfare. In this article, the authors investigated about the actual legislation framework on energy communities at the European and Italian level, highlighting regulatory problems and barriers that are delaying their constitutions. The authors propose a “power sharing model” (PSM), which is useful for energy communities based on the sharing of renewables and other energy services. The PSM is suitable for both the building level and larger communities. PSM has been analyzed through a case study that regards the preliminary study of a smart microgrid that should be realized in Campobasso, Italy, to connect buildings of the public administration. This scenario was investigated through a simulation conducted in Simulink environment where the control strategy was implemented, and the results were compared to a traditional configuration for renewable sources integration. The results highlight the adequacy of PSM for the energy community for the building's microgrids application.

建筑能源社区的电力共享模型

修订后的欧洲促进可再生能源指令（2018/2001）引入的可再生能源社区的新概念为微电网开辟了新的可能性。事实上，它允许提高可再生能源在“能源社区”内共享它所产生的能源的价值，并增加社会福利。在本文中，作者调查了欧洲和意大利层面能源社区的实际立法框架，强调了推迟制定宪法的监管问题和障碍。作者提出了一种“电力共享模型”（PSM），它对基于可再生能源和其他能源服务共享的能源社区很有用。PSM 适用于建筑层和更大的社区。PSM 已经通过一个案例研究进行了分析，该案例研究应该在意大利坎波巴索实现智能微电网的初步研究，以连接公共行政大楼。通过在 Simulink 环境中实施控制策略的模拟来研究该场景，并将结果与​​可再生能源集成的传统配置进行比较。结果突出了 PSM 对能源社区建筑微电网应用的充分性。并将结果与​​可再生能源整合的传统配置进行了比较。结果突出了 PSM 对能源社区建筑微电网应用的充分性。并将结果与​​可再生能源整合的传统配置进行了比较。结果突出了 PSM 对能源社区建筑微电网应用的充分性。
