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) circuits. And without electrical models, it is hard to do what-if calculations for solar PV, electric vehicles, etc. Taking advantage of historical smart meter data, this project will demonstrate that is possible to capture the physics of three-phase LV circuits and create a model-free approach to calculate voltages.
This project will provide the technical foundations for distribution companies to carry out voltage calculations without employing electrical models of low voltage (LV) circuits but, instead, exploiting primarily historical smart meter data. These model-free calculations can be used to estimate the maximum power exports or imports of individual customers (also known as operating envelopes) as well as to assess the impacts (or hosting capacity) of residential solar PV or electric vehicles.
This 2-year project (Jul 2021 to Jul 2023) is funded by the Centre for New Energy Technologies (C4NET) and involves the Australian distribution companies AusNet Services, Jemena, CitiPower & Powercor, and United Energy.
