Impacts of a reduction in 11 kV voltage settings in South Wales

Research output: Contribution to journalArticlepeer-review


This study investigates the impacts on the low-voltage distribution network of a reduction in 11 kV voltage control settings. Through the use of statistical modelling, the effects of a real-life reduction in voltage settings were measured and quantified. This highlighted statistically significant reductions in average real power demand, maximum real power demand and average reactive power demand. A reduction in demand of the magnitude observed would equate to an estimated saving of £14.9 million for customers if all substations in South Wales were changed.
