Query: Hybrid European MV-LV Network Models for Smart Distribution Network
  Modelling   A pair of European-style, integrated MV-LV circuits are presented, created by
combining generic MV and real LV networks. The two models have 86,000 and
113,000 nodes, and are made readily available for download in the OpenDSS file
format. Primary substation tap change controls and MV-LV feeders are
represented as three-phase unbalanced distribution network models, capturing
the coupling of voltages at the MV level. The assumptions made in constructing
the models are outlined, including a preconditioning step that reduces the
number of nodes by more than five times without affecting the solution. Two
flexibility-based case studies are presented, with TSO-DSO and peer-peer-based
smart controls considered. The demonstration of the heterogeneous nature of
these systems is corroborated by the analysis of measured LV voltage data. The
models are intended to aid the development of algorithms for maximising the
benefits of smart devices within the context of whole energy systems.
