Adding unified grid simulation example for NCIM

Hello, You might be running into a folder‑permission issue. Could you try copying the model into a public folder like Documents, opening it from there, and giving it another try? Also, which version of the software are you currently using? Best,

Hello, Sorry for the delay in getting back to you. I took a look, and everything appears to be working as expected. I should mention that I’m currently using version 7, but I don’t recall making any changes to that part of the code when moving to the new version. I’m attaching a simple script you can use to verify the communication between DSS‑G and a remote client. You’re right that the simulation mode doesn’t refresh automatically after a DSS command is sent from a remote client, I’ll take care...

DSP files are no longer needed. Now DSS-G interacts directly with the .dss files for plotting and searching functions. Preparing environment for including map functions (GIS) directly from the GUI.

Hi Joe, It sounds like you’re trying to use FaultStudy mode for this, but unfortunately that won’t give you the results you’re looking for. As explained here (https://opendss.epri.com/FaultStudyMode1.html), the fault analysis only accounts for injections from sources and generators. A PCE like a PVSystem is brought into the model as a negative Y‑primitive, which is why you’re seeing the values being reported. A better approach is to explicitly add a fault and run the simulation in snapshot mode....

Hello, This was quite a query, but I think I have the answers you need: Considering the differences in fault currents for almost every buses in "ALL-Node Fault Currents" in text1, the 3-Phase fault is modeled as an unsymmetrical fault. Is my understanding correct? I would check the fault study mode notes in which Roger back in the day explained the differences between a regular snapshot simulation and fault study. https://opendss.epri.com/FaultStudyMode1.html . Given the workflow explained at this...

Another option would be to install NI LabVIEW in your PC (you can download the community version) and run the source code itself. The code can be downloaded from: https://sourceforge.net/p/dssimpc/code/HEAD/tree/trunk/Source/ You can use any SVN client for that. The instructions for learning how to run the source code locally with a local NI LabVIEW installation are available here: https://sourceforge.net/p/dssimpc/code/HEAD/tree/trunk/Source/README_FIRST.txt Best,
