Topic: “The Future of DER Hosting Capacity and Operating Envelopes”
Abstract: Distribution companies, who manage the poles and wires, struggle to have accurate and up-to-date electrical models of their residential areas, known as low voltage (LV) networks. And without electrical models, it is hard to assess the hosting capacity for distributed energy resources (DER) such as solar PV or electric vehicles; particularly when voltages are likely to be a major issue. Similarly, the calculation of operating envelopes requires quantifying the voltage effects from different exports or imports.
Taking advantage of historical smart meter data, this talk will demonstrate that is possible to capture the physics of three-phase LV networks and create an electrical model-free approach to calculate voltages which, in turn, allows the calculation of DER Hosting Capacity and Operating Envelopes.
Using Neural Networks, the nonlinear relationships among the historical data (demand and voltages) and the corresponding LV networks can be captured. This approach can make it possible for distribution companies to bypass the time-consuming process of producing LV network models and, instead, carry out accurate, extremely fast voltage calculations for any type of what-if scenarios involving residential solar PV, batteries, electric vehicles, etc.
