Analysing the Long-Term Impact of the Energy Transition on Medium Voltage Network Assets

This paper proposes a new methodology to analyse the long-term impact of the energy transition on Medium Voltage (MV) network assets. The impact will be realized in the long term by including the impact of renewable technologies on medium to low voltage transformer loadings. To ensure future networks can be analysed, adoptions of technologies connected on low and medium voltage networks are modelled and can be altered on a neighbourhood level. Furthermore, curtailment and flexibility can be taken into account in the impact analysis. To find nodes and cables prone to voltage violations and overloading, this proposed model is validated on a typical urban, rural and industrial MV network for a scenario with peak demand (winter) -and generation (summer) during normal and redundant operations. It is found that urban networks are more likely to have a cable overload, whereas rural networks are more likely to have voltage violations. Industrial networks are highly dependent on where the large-scale installations are connected to the networks.
