Synthetic Eastern US 70,000-bus power system model.

This is an entirely synthetic 70,000 bus case, geographically situated
in the Eastern US. The case is designed with a 765, 500, 345, 230, 161,
138, 115, 100 and 69 kV transmission network to serve a load that
roughly mimics the actual population of its geographic footprint. The
synthetic transmission system was designed by algorithms described in
[1] to be statistically similar to actual transmission system models
but without modeling any actual lines.

This is a synthetic power system model that does not represent the
actual grid. It was developed as part of the US ARPA-E GRID DATA
research project and contains no CEII.
