IEEE 34-Bus Test Feeder (with modifications)
! Original source: https://github.com/tshort/OpenDSS/tree/master/Distrib/IEEETestCases/34Bus
! Modified for studying datacenter loads connected to distribution grids.
!
! Modifications from the original:
! - All line lengths halved from the original to create a shorter/stiffer feeder
! The original IEEE 34-bus is an unusually long rural feeder (~60 miles);
! halving the lengths produces more realistic voltage drops for datacenter-scale load studies.
