A pair of European-style, integrated MV-LV circuits are presented, created by\ncombining generic MV and real LV networks. The two models have 86,000 and\n113,000 nodes, and are made readily available for download in the OpenDSS file\nformat. Primary substation tap change controls and MV-LV feeders are\nrepresented as three-phase unbalanced distribution network models, capturing\nthe coupling of voltages at the MV level. The assumptions made in constructing\nthe models are outlined, including a preconditioning step that reduces the\nnumber of nodes by more than five times without affecting the solution. Two\nflexibility-based case studies are presented, with TSO-DSO and peer-peer-based\nsmart controls considered. The demonstration of the heterogeneous nature of\nthese systems is corroborated by the analysis of measured LV voltage data. The\nmodels are intended to aid the development of algorithms for maximising the\nbenefits of smart devices within the context of whole energy systems.\n
