Supporting DER customer participation in active distribution networks and local markets

Abstract: The growth of distributed generation in the UK has led to the increase in the number of flexible Distributed Energy Resource (DER) connections and services required at distribution level. In some parts of the UK, flexible connections are offered to Distributed Generators (DG) via the use of Active Network Management (ANM) systems. In exchange for a cheaper, quicker connection to the network, DG may be subject to curtailment when the network is constrained. This paper presents a Virtual Private Wire (VPW) solution that can allow generation and demand within the same ANM system to be linked in association with specific network constraints. Smarter Grid Solutions developed a demonstration system in order to show the effect of a VPW arrangement in the SP Energy Networks Accelerating Renewable Connections (ARC) trial area. This paper draws conclusions on both commercial and technical issues as well as solutions for local network balancing introduced by the VPW concept. The future direction for control architectures required to support VPW and multiple other new DER management applications is also set out, along with the wider market and system implications of coordinated DER control and local system balancing.

Implementing optimisation functionality on network management platforms for new DSO business models

Abstract: This paper address the emerging need for Distribution System Operators to optimise Distributed Energy Resources hosted in their networks. This paper presents the Active Network Management (ANM) technology platform elements developed and tested by the authors to host DSO optimization functionality and the requirements this addresses including: control platform architecture and properties; level of autonomy; solution speed for different use cases; fail-to-safes; real-time override; operator configuration and interface; market and system operator integration. The paper also presents results of end-to-end lab test of the optimization platform and applications with an objective evaluation of the outcomes and outlook for further development towards implementation by DSOs. Conclusions are drawn and presented on the technical, commercial business model and regulatory implications of implementing optimization functionality to deliver new DSO business models.
