Abstract

The envisaged load growth and ageing of assets require optimal distribution network replacement strategies. Losses inclusive network design results in network capacity significantly larger than the peak demand requirements. Given significant future low and medium voltage network spare capacity, in this paper, the potential for cost-effective incremental enhancement of security of supply is investigated. The analysis shows that long-term economically efficient design of low voltage networks and underground medium voltage networks is N-1. The range of economically efficient designs of overhead medium voltage networks is observed, from N-0 for reliable networks with low loading to N-1 for unreliable networks with high loading at value of lost load of £17,000/MWh.
