Power Distribution Networks Planning in Meshed Loop-Feeder or Open-Loop Topology

This dataset contains some case studies referring to the optimal planning of MV distribution networks with meshed (loop feeder, LF, and open loop, OL) topology.
The folder "Case studies" contains .xlsx files of three different test cases:
1) Case A (small-size test case): A small portion of the city center of Florence, Italy, with 20 secondary substations, 2 primary substations, and 230 candidate branches.
2) Case B (medium-size test case): The town of Assisi, in central Italy, with 50 secondary substations, 3 primary substations, and with a total of 1100 candidate branches.
3) Case C (large-size test case): A significant portion of the city of Terni, in central Italy, with 117 secondary substations, 3 primary substations, and 1628 candidate branches.
In all test cases, secondary and primary substations are arbitrarily placed along the city.
Each .xlsx file contains:
1) Sheet "Nodes": the complete list of nodes, each with name, typology (load node, root node), coordinates (latitude and longitude), active and reactive power demand.
2) Sheet "Branches": the complete list of candidate branches, each with names of from_node and to_node, length, ampacity, branch capacity, WGS84 coordinates of the road path of the branch, status in the LF optimal solution, status in the OL optimal solution (1 = branch is connected, 0 = branch is not connected). For each candidate branch, an underground cable with a series impedance of 0.206 + j 0.092 Ohm/km per phase is
assumed. DUmax = 8% is the maximum allowable voltage drop.
The folder "Maps" contains the optimal meshed topologies (both LF and OL topology) of the three case studies with selected candidate branches reported in the street layout and the whole network visualized on a map. OpenStreetMap is used. In Case A and Case B LF and OL optimal topologies are the same.
