Lessons Learned Report: Enhanced Automatic Voltage Control
Overview
This report presents a comprehensive overview of lessons learned during the installation, integration and commissioning of Enhanced Automatic Voltage Control (EAVC) for the Customer-Led Network Revolution (CLNR) project. It is intended for use by distribution network operators and other interested parties who are considering embarking on or undertaking similar projects.
The CLNR project has successfully pioneered trials of Enhanced Automatic Voltage Control (EAVC). One of a number of smart solutions being trialled through Northern Powergrid’s Low Carbon Networks Funded CLNR project, EAVC solutions perform in a similar way to traditional Automatic Voltage Controllers. However, the key differential is that EAVC’s voltage setpoints can be adjusted remotely through a communications channel by an Active Network Management system, such as the Grand Unified Scheme which was developed for the project.
Lessons learned for each of the network-based technologies were gathered throughout the project via a series of structured workshops. The workshops were complemented and supported by site visits and follow-up with key personnel to reflect on the progress of the project and any aspects which challenged or offered learning opportunities.
This report presents the lessons learned relating to the implementation of EAVC systems on the HV and LV network, both where the project has been successful and where, with the benefit of hindsight, a different approach could be adopted for future implementation.
