The paper focuses on the day-ahead operational planning of a grid-connected local energy community (LEC) consisting of an internal low-voltage network and several prosumers including generation units, battery storage systems, and local loads. In order to preserve, as much as possible, the confidentiality of the features of prosumers’ equipment and the production and load forecasts, the problem is addressed by designing a specific distributed procedure based on the alternating direction method of multipliers (ADMM). The distributed procedure calculates the scheduling of the available energy resources to limit the balancing action of the external grid and allocates the internal network losses to the various power transactions. Results obtained for various case studies are compared with those obtained by a centralized optimization approach. The results confirm that, in the considered LEC framework, each of the prosumers achieves a reduction in costs or increases revenues in case it participates to the LEC with respect to the case in which it can only transact with an external energy provider.

本地能源社区的日前调度：乘法器方法的交替方向方法

本文重点介绍并网本地能源社区 (LEC) 的日前运营规划，该社区由内部低压网络和包括发电机组、电池存储系统和本地负载在内的多个产消者组成。为了尽可能地保护产消者设备特性以及生产和负荷预测的机密性，通过设计基于乘法器交替方向法（ADMM）的特定分布式程序来解决该问题。分布式程序计算可用能源的调度以限制外部电网的平衡动作，并将内部网络损耗分配给各种电力交易。将各种案例研究获得的结果与集中优化方法获得的结果进行比较。
