利用分布式能源（DER）的灵活性被视为实现可再生能源发电在电力系统中的高渗透的重要贡献。然而，目前电力系统中的控制基础设施不太适合大量小型机组的集成。一种常见的方法是将这些单元组合在一起，并将它们作为一个单一的大型虚拟单元暴露给电力系统。为了实现智能电网的愿景，需要灵活、有弹性和可靠的聚合基础设施的概念。本文提出了这一概念，并着重讨论了弹性和容错方面的问题。提出的概念利用多级选举算法透明地管理单元的添加、删除、故障和重组。它已经作为概念验证在丹麦技术大学的分布式智能电网测试平台SYSLAB上实施和测试。
Exploiting the flexibility in distributed energy resources (DER) is seen as an important contribution to allow high penetrations of renewable generation in electrical power systems. However, the present control infrastructure in power systems is not well suited for the integration of a very large number of small units. A common approach is to aggregate a portfolio of such units together and expose them to the power system as a single large virtual unit. In order to realize the vision of a Smart Grid, concepts for flexible, resilient and reliable aggregation infrastructures are required. This paper presents such a concept while focusing on the aspect of resilience and fault tolerance. The proposed concept makes use of a multi-level election algorithm to transparently manage the addition, removal, failure and reorganization of units. It has been implemented and tested as a proof-of-concept on the distributed smart grid test bed SYSLAB at the Technical University of Denmark.
