This project has no operational element as the monitoring equipment is already in place. The University of Bath shall analyse the large database of voltage current and power measurements for the area. This will include whole year of data following the voltage change.

The detailed areas to be assessed are:

  • The effect of seasonality on consumption reduction

  • The effect of customer make up on consumption reduction

  • The effect of seasonality on demand reduction

  • The effect of customer make up on demand reduction

  • The effect of the 11kV voltage reduction on LV voltage profiles

  • The effect of temporary voltage reduction on demand and consumption (investigate the effects of National Grid’s operation Juniper on our monitored network).

The objective of this project is to refine our estimates on the effects of voltage reduction on consumption, demand and voltage profiles.
By understanding the effects of key parameters current predictions can be improved and the benefits better understood. The assessment of existing profiles should also indicate the available scope for further reduction.
 

There are multiple success criteria:

  • Quantify the effect of seasonality, time and substation type on consumption reduction

  • Quantify the effect of seasonality, time and substation type on Maximum demand reduction

  • Quantify the effect of 11kV voltage reduction on LV substation and feeder end voltage distributions

  • Refined estimate of the benefits of voltage reduction as well as the scope for further reduction
