Advanced replacement strategies for low voltage distribution grids

Abstract

Low voltage distribution grids play an important role in the energy transition-both in generation and demand. In the coming decades the reliability of these grids may deteriorate due to asset ageing. Various maintenance (replacement) strategies are compared in order to mitigate this. For multiple scenarios, it is analysed under which circumstances and when alternative strategies are more profitable than current practice towards managing low voltage assets. Under all scenarios utilities are advised to actively seek collaboration with other utilities and institutions in order to increase efficiency, reduce nuisance, achieve future-proofness and minimise risks. Also, opportunities for condition-based approaches exist with the increasing application of distribution automation.
