Unexpected very long lines in MV grid #253

Open maltesc opened 6 years ago

maltesc commented 6 years ago

I just saw a wrong assignment of a generator or load to a MV grid very far off (see red line in screenshot from 2018-03-13 14-03-01.

This case is MV grid 792, Line_7920002

Thanks for reporting! Could you please provide the geno_id? I tried to open your DB table model_draft.corr_vis_mv_lines to get more details but got no permissions..

maltesc commented 6 years ago

The purpose of the vis tables simply is the visualization of my results and they constantly change. However, you can have a look at my tables model_draft.corr_mv_lines_results and model_draft.corr_mv_bus_results where I store all my eDisGo results. You should have access to those now. The mentioned line appeared in result_id = 384. The connected generator is Generator_433693. I hope this helps a little...

Uhh, semms that there're some more lines affected: line_bug

The geno with id = 433693 seems to be in Bavaria whereas HV/MV (id = 792) and MV/LV (id = 285975) stations are in Berlin (all data from dp v0.3.0). There seems to be an issue with the assignment of the geno to the right HV/MV station.

2 example genos:

SELECT *
  FROM supply.ego_dp_res_powerplant
  WHERE version='v0.3.0'
  AND id =in (433693, 19030);

Striking: Both genos are flagged (rea_flag) with M4_rest @Ludee U got an idea?

Check that an error is thrown if a generator with a too big distance is connected to the grid.
