pandapower - pandapower 1.5.0

Changes in pandapower 1.5.0:

• Improved two-winding transformer modeling:
  • Transformer taps could previously only be set as ideal phase shifters (tp_st_degree > 0) or linear regulators (tp_st_percent >0). Now, tap changers can also be defined as cross regulators (tp_st_degree > 0 and tp_st_percent >0). The cross regulator model is validated against PowerFactory.
  • The basic standard type data for HV/MV transformers has been updated with more realistic values.
• Improved three-winding transformer modelling:
  • taps could previously only be modelled at the terminals, and can now also be modelled at the star point.
  • The open loop losses were previously modelled at the HV equivalent transformer. They can now be modeled at the star point, HV, MV or LV side.
• A new storage element has been introduced in net.storage.
• Dielectric active power losses of lines can be modelled using the new parameter net.line.g_us_per_km.
• The short-circuit module now also supports single phase fault calculations.

A Paper describing pandapower has been accepted for publication in IEEE Transactions on Power Systems. A preprint of the paper is available on IEEE Xplore or alternatively on arXiv. The paper is accompanied with a case study that showcases the capabilities of pandapower, the code for which is available on github as jupyter notebooks. We kindly ask anyone to acknowledge the usage of pandapower in scientific works by citing this paper. The bibtex citation can be found in the documentation.
