Buses are not connected as per MATPOWER casefile #25

Closed aakanksha512 closed 6 years ago

aakanksha512 commented 6 years ago

When I load my MATPOWER case, the buses are not connected to each other as per branch connections in the case. Please let me know if there is any specific format for data input in stac.

Can you give a specific example that is not working? I just tried some cases from https://github.com/power-grid-lib/pglib-opf and it seemed to be working fine.

aakanksha512 commented 6 years ago

Hi, Attached is the matpower file I am working on. When I upload the file on stac...it just plots the buses and does not connect the branches. I think it is something to do with the format of data. Transmission.txt

ccoffrin commented 6 years ago

This file uses a combination of spaces and tabs for defining the matrices. Try making these consistent.

aakanksha512 commented 6 years ago

Ok thanks, I will correct and get back to if it works.

ccoffrin commented 6 years ago

From inspecting the javascript console, it is clear that there is some issue in parsing the branch table. The other tables appear to be fine.

aakanksha512 commented 6 years ago

Hi, I tried to make the tables consistent, but now it says 'Unable to parse the input file.' I have attached the file for your reference. Please let me know what other changes I need to do in the matpower file. Transmission1.txt

ccoffrin commented 6 years ago

In the branch list there was one row with a double indent, which broke the parser. This looks like it should work. btw, the transformer tap ratios look a bit weird. Transmission2.txt

aakanksha512 commented 6 years ago

Hi Carleton, Thanks for reviewing my code. I am able to plot it on stac. For the transformer tap-ratio, I used the conversion of voltages in the transformers i.e. if a substation A is at 500kV and substation B is at 230kV, so tap ratio for the branch connecting A to B I have taken as 500/230. Also, when I input the file into stac, almost all the branches give errors 'charge is very different from x' and 'Charge value greater than 0 for transformers'. Can you help me as to what these errors mean and how can I improve my model? Thanks!

Great to hear your case is now working. I am going to close this issue. For your question regarding network parameters, that is best sent to the PowerGlobe mailing list.
