  This work proposes a framework to generate synthetic distribution feeders
mapped to real geo-spatial topologies using available OpenStreetMap data. The
synthetic power networks can facilitate power systems research and development
by providing thousands of realistic use cases. The location of substations is
taken from recent efforts to develop synthetic transmission test cases, with
underlying real and reactive power in the distribution network assigned using
population information gathered from United States 2010 Census block data. The
methods illustrate how to create individual synthetic distribution feeders, and
groups of feeders across entire ZIP Code, with minimal input data for any
location in the United States. The framework also has the capability to output
data in \OpenDSS format to allow further simulation and analysis.
