This is the Final Report of the project “Model-Free Operating Envelopes at NMI Level”. This report builds on the previous project reports and presents the final version the model-free OE approach and the main findings of the final 6 months of the project.
To overcome the lack of electrical models, this project has successfully demonstrated that is possible to exploit the historical smart meter data of customers to capture the physics of three-phase LV networks and create an electrical model-free approach to calculate voltages. These model-free voltage calculations can then be used along with a heuristic algorithm and tailored approximations to assess several import or export values for active customers (i.e., customers engaged with aggregators) and thus, determine its corresponding OEs. This approach represents an accurate, cheap, and extremely quick alternative to traditional model-based approaches, enabling DNSPs to bypass the costly, time consuming, and error-prone process of producing and validating electrical models.
