Hello Abdullah, Apologies for the delay in responding. The old population script located under the taxonomy_feeders repository should still work, but you do have to modify the IEEE feeders (because the script is looking for triplex_meter and triplex_node objects). There is an IEEE 8500-node version located under the tools repository -- I don't know if that still works though. There is an updated population script associated with the GridAPPS-D project a version can be found here, but I don't know...

Hello Abdullah, Since this is basically the same as your other question located here, please see that message. -Frank

Hello Adbullah, Based on the type of data Jerry included in the original email, my guess would be a load object was used load wiki page. That type of CSV could probably be just "played" into the base_power_X fields (you may need to divide it by 3 and set for each of the three phases). That would allow you to set specific ZIP fractions/power factors too, if there's a specific type of load you are emulating. -Frank

Hello Swastik, Those values are arbitrary, set to be "high" as to not trigger warnings when people aren't concerned about them. So the calculation was "that looks like a nice big, round number - good enough!". I'll also note that the functionality is quite limited, mostly with them throwing a warning of "line is overloaded" (but I believe the violation_recorder looks for overloads). As you mentioned, that 4.16 MVA (actually closer to 12.48 MVA, since that is a per-phase check) is quite high. Reaching...

Hello Abdullah, Since the post is over 5 years old, I'd be surprised if Cody responds. There are some feeder generators/population scripts under the GridLAB-D Git repository, or there's one part of the Transactive Energy Systems Project (specifically located here) that people have had luck with in the past (and is much newer than the scripts in the GridLAB-D repository). -Frank

Hello Loraine, Unfortunately, we deprecated the MATLAB functionality a couple versions ago (v5.0 or v5.1 silently stopped including it). The preferred approach at the moment is to use the HELICS cosimulation platform as the communication method between GridLAB-D and MATLAB (among other things). Due to how the MATLAB API kept changing and some of the limitations of our existing implementation, HELICS probably provides the most capability to interface with MATLAB at the moment. -Frank

Hello Jerry, Apologies for the delay in the response. "Probably". It depends what format your load profile is in. The obvious choice is usually as some sort of player object, where you use that to push the data to a powerflow load object. If you haven't done so, you may want to check out the webinar recordings we have, or the GridLAB-D Tutorial to get some ideas on how that could be incorporated into the system. Depending on the data, you may also be able to do it via the MySQL interface or using...

Hello Mamun, Apologies for the delay in getting back to you on this. Technically, it is possible to run GridLAB-D in Python, but only by manually calling the executable (with something like popen or similar). There's a simple example up on the GitHub tools repository. For HELICS, if you download the compiled executable for GridLAB-D, you'll need the complimentary compiled binaries for HELICS. Since you're using Python, you'll want to consult the HELICS repository and forums/tickets for the most up...
