Impacts of photovoltaics on low voltage networks: A case study for the North West of England

This work proposes a Monte Carlo-based technique to assess the impacts of different PV penetrations on a real LV network for the North West of England, considering 5-min resolution models for domestic load and PV generation. The impacts of PV location are analysed through two scenarios based on location: closer to and further from the distribution transformer. Voltage impacts are measured using EN50160 and the thermal capabilities are examined through a utilisation factor. Additionally, the effects of higher LV busbar voltages are also investigated. Results indicate that voltage issues are more constraining than asset utilisation, particularly with clusters closer to the transformer.
