[IMPROVEMENT] Compatibility with upcoming Pandapower release. #330
Description
Describe the problem
As per PP Change Log, following change is being made in upcoming release:
[CHANGED] separate voltage dependencies for P and Q for loads: const_z_percent –> const_z_p_percent, const_z_q_percent, const_i_percent –> const_i_p_percent, const_i_q_percent
(https://pandapower.readthedocs.io/en/latest/about/changelog.html)
This change will break "_create_pgm_input_sym_loads" method as "const_i_percent" and "const_z_percent" attributes will not be available in latest release of Pandapower.
Improvement proposal
Alter the method to handle upcoming changes, however, to keep backward compatibility with older versions of PP, make changes based on current pp version.
- Implement separate ZIP model for P & Q
- 3ph loss columns for line & trafo renamed to "pl_a_mw" instead of "p_a_l_mw" and so on.
