    Abstract

    (paper accepted) Understanding the current behaviour of low voltage distribution feeders is crucial to assess the impacts of low carbon technologies (LCTs) in low voltage (LV) distribution networks. Only by knowing the main parameters in the base case, i.e., without LCTs, it is possible to estimate the potential effects of adopting these technologies. However, the knowledge about the infrastructure at this voltage level is limited. In fact, most of Distribution Network Operators (DNOs) do not monitor LV networks, mainly because of the historic passive nature of these circuits and the assumption that demand and diversity would not change dramatically. Nonetheless, this historic framework is challenged by the increasing adoption of LCTs. In this context, this work analyses real 10-minute resolution data from more than 100 UK LV substations (500+ feeders), considering two seasons (winter and summer), and the presence of photovoltaic systems. In particular, three key parameters are investigated: voltage at the busbar, power factor, and imbalance level for all the cases under analysis. This analysis increases the understanding of current UK LV networks that can then be used to improve modelling and design approaches.
