Abstract

This paper presents the trial results of a real-time, centralised voltage control system for 33kV and 11kV electricity distribution networks, called System Voltage Optimisation. System Voltage Optimisation dynamically adjusts the previously static target voltage settings of the substations’ voltage control relays in order to release network capacity and has been implemented and trialled in the UK by Western Power Distribution as part of the Network Equilibrium innovation project. The trials of System Voltage Optimisation have proved the successful operation of the technology and provided valuable knowledge on the capability of optimising 33kV and 11kV network voltages in real time. The learning gained on the operation and performance of the technology through the analysis of the trial results is discussed in this paper. The usage of the trial results to improve the power system analysis planning tool that has been developed and the evaluated capacity benefits are also presented in this paper.
