Advanced planning of PV-rich distribution networks: HV-LV modelling of selected HV feeders
The project is established to develop analytical techniques to assess residential solar PV hosting capacity of electricity distribution networks by leveraging existing network and customer data. Additionally, planning recommendations will be produced to increase the hosting capacity using non-traditional solutions that exploit the capabilities of PV inverters, voltage regulation devices, and battery energy storage systems. This document first presents the process adopted to select the HV feeders going to be used in the project. Chapter 3 details the procedure adopted to extract and process all feeder data to develop the corresponding digital feeder models considering different aspects and assumptions. Chapter 4 presents the topology and general characteristics of all fully modelled feeders along with a case study that considers a peak demand day time-series power flow analysis using the software OpenDSS. The corresponding analyses, which consider realistic demand data, help understanding the level of the detailed modelling performed while demonstrating the expected behaviour of each of the feeders.
