Introduction: In contrast to typical UK practice of using OLTCs as a means of primary voltage control, a technique termed Conservation Voltage Reduction (CVR) is often used on distribution networks overseas to control feeder voltage profiles. This project will investigate the potential of this CVR technique to manage and manipulate feeder voltage profiles. Its aim is to ascertain if it could realistically be used to facilitate the connection of intermittent renewable energy generation that may wish to connect to the network in remote locations where renewable energy resources are high but the network may be weak with regard to voltage control. The project will employ pole mounted 11kV capacitor banks with an integrated vacuum switch and controller which can be used to control the switching around various set points including power factor and voltage. In addition academic studies will be carried out to analyse the ‘before and after’ effects and to define the technical and financial benefits.

Objectives: CVR is a widely used technique in many counties and this project aims to demonstrate its viability to UK networks.
