This is a major release because of the following non-backwards compatible changes:

  • The units have been changed from kW/kVAr/kVA to MW/MVAr/MVA in all elements #73
  • The signing system from load to generation in gen, sgen and ext_grid #208

In addition, multiple parameter names and conventions have been changed:

  • The system of cost functions has been changed fundamentally #211
  • all trafo tap parameters are changed from 'tp' to 'tap' and 'tp_mid' changed to 'tap_neutral' #246
  • all trafo short-circuit voltage parameter names have been changed from "vsc" to "vk" #246
  • create_nxgraph adds edges in multigraph with key=(element, idx) instead of key=0,1.. #85
  • the definition of measurements in the measurement tables has been changed #343

New functionality has also been added:

  • An interface to PowerModels.jl for OPF #207
  • Temperature dependent line impedance in the power flow #283
  • Possibility to model bus-bus switches with a resistance #259
  • Proper initialization from results for auxiliary buses #236
  • Support for trafo3w switches in create_nxgraph #271
