Report: On the Implementation and Publishing of Operating Envelopes (PDF 1MB)
The report covers the development and promotion of standards in relation to the communication of registration, monitoring and envelope information between DER assets, aggregators and Distribution Network Service Providers.
The orchestration of DER on the low-voltage network via dynamic operating envelopes represents a significant capability to increase network utilisation, but comes with additional data sources and calculations orders of magnitude beyond current DNSP practices.
The challenge of scaling to a solution that can manage (potentially) millions of smart controllable resources is significant. There is no single solution to this challenge – it requires careful consideration of architectures, protocols, and technologies used to implement such a system. This report considers, in particular, the interface between aggregators (or end devices) and DNSPs, and addresses the implementation of protocols, protocol extensions, and architectural decisions made in this implementation. Some of the many open questions involved in operating at scale are also discussed.
No single project will have answers to all of these questions, but the contributions from each project will build on previous experience to move the industry toward a secure, clean grid. To that end, we consider that the work of publishing open-source software to be vital, not just in this project, but within the industry more generally.
