With the increased penetration of distributed renewable energy sources (DRES) in the grid, new pathways are required to keep the electricity distribution system stable. The provision of ancillary services (AS) by the DRES can contribute in this regard. However, it is necessary to communicate the need for AS from the third party providers such as distribution system operator (DSO) to the DRES in an efficient and scalable manner. To this end, a flexible information and communication technology (ICT) architecture is presented in this paper, and the requirements for the architecture are elaborated. We argue that this architecture is capable of supporting the present and future needs of electricity distribution networks. To illustrate its utility and effectiveness, an accounting use case for DSOs has been presented; it describes a remuneration scheme for the AS provision. A dashboard has been developed to enable communication via this architecture and to allow control of the grid. In addition, a distributed ledger technology for the realization of accounting has been analysed with respect to its scalability and performance capabilities.

灵活的ICT体系结构，以支持未来的配电网络中的辅助服务：DSO的会计用例

随着分布式可再生能源（DRES）在电网中的渗透率不断提高，需要新的途径来保持配电系统的稳定。DRES提供的辅助服务可以在这方面做出贡献。但是，有必要以高效且可扩展的方式将对AS的需求从第三方提供商（例如配电系统运营商（DSO））传达到DRES。为此，本文提出了一种灵活的信息和通信技术（ICT）架构，并阐述了对该架构的要求。我们认为这种体系结构能够满足当前和未来的配电网络需求。为了说明其效用和有效性，提出了DSO的会计用例。它描述了有关AS的薪酬计划。已经开发了仪表板以允许通过该架构进行通信并允许控制网格。另外，已经针对其可扩展性和性能来分析了用于实现计费的分布式分类帐技术。
