摘要

本文主要研究了通过调度成员负荷来优化能源社区集体自用率的问题。该社区与公共电网保持连接,包括亲消费者、传统消费者和分布式存储单元。产消者可以与公共电网或其他成员交换他们的能源。提出的策略旨在实施需求侧管理方案,利用可控负荷的特点。一方面,该问题的MILP公式允许给出电气设备操作的最佳规划。另一方面,它为管理存储单元、点对点交换以及与公共电网的交互提供了最佳解决方案,以最大限度地减少公共电网随时间的能量流。然而,这个MILP只允许解决小的问题实例。因此,我们为大型问题实例开发了基于列生成的启发式方法。我们根据在法国南部收集的真实数据进行的数值实验表明,加入一个能源社区可以节省能源账单的钱,并将从初级电网获取的总能源减少至少15%。

Loads scheduling for demand response in energy communities
This paper focuses on optimizing the collective self-consumption rate in energy communities by scheduling members’ loads. The community remains connected to the public grid and comprises pro-sumers, traditional consumers, and distributed storage units. Prosumers can exchange their energy with the public grid or other members. The proposed strategy aims at implementing a Demand Side Management program taking advantage of controllable loads’ characteristics. A MILP formulation of the problem allows, on the one hand, to give the optimal planning for electrical devices’ operations. On the other hand, it provides optimal solutions for managing the storage units, peer-to-peer exchanges, and interactions with the public grid to minimize the energy flows from the public grid over time. However, this MILP only allows for solving small problem instances. Thus, we develop a column generation-based heuristic for large problem instances. Our numerical experiments based on real data collected in the south of France show that joining an energy community saves money on energy bills and reduces the total energy drawn from the primary grid by at least 15%.
