Improve performance of Temperature-Dependent Power Flow calculation

1

In the present implementation, the functions to expand the Jacobian matrix for the TDPF calculation are not written in a way to have the best possible performance. Because of that,...

This would add the possibility for controllers etc. to be saved in: - Excel files - SQLite files - PostgreSQL DB

convert_format: adding missing columns

2

Can adding missing columns be done authomatically and not individually in the convert_format function?

if the grid model has not continuous indices of elements ([4,56,78] instead of [0,1,2]), there are errors while running 3ph power flow. It seems to be caused by using position-based...

Inconsistent behavior of load and asymmetric_load

2

I observed the following behavior of pp.runpp and pp.runpp_3ph regarding the elements load and asymmetric_load: 1) runpp The elements load and asymmetric_load both impact the results. Having asymmetric_load elements activated...

Implement distributed slack calculation for grids with separate zones

2

The implementation of distributed slack calculation has been merged: https://github.com/e2nIEE/pandapower/issues/771 https://github.com/e2nIEE/pandapower/pull/1298 A point that is still open is a calculation in grids that have multiple separate zones. To this end,...

pandas 1.0 was released 2 years ago, and we still have multiple checks for pandas versions for even 0.2 For context: v0.20.3 (July 7, 2017) v0.23.0 (May 15, 2018) 1.0.0...

MATPOWER case format allows user—defined variables e.g. bus names etc. We implemented loading them to net._options to give the user a possibility to process such variables after loading net. #1468...

NaN is cast to True in Python. This can be problematic if a value in a bool column (e.g. in_service) is set to NaN by mistake. It depends on the...
