Regulator representation between OpenDSS and conversion XML file

[motareddy]

Hi,

I am working on regulator control using VVO. At present working on an IEEE 123 feeder inside the GridAPPS-D platform. It seems like out of 4 regulators, three regulators can control when I noticed the model dictionary file. However, the representation of one of the regulators was quite confusing when I compared it with the OpenDSS file. Can anyone help me find the correct detail representation inside GridAPPS-D?

What was the confusion when you compared it with OpenDSS? Please note that 3 out of 4 transformers have tank names and the substation regulator (reg1a) is defined as a PowerTransformer in CIM.

One transformer of a regulator is designated in the model dictionary file as reg4 and its vgrp. From the OpenDSS file, I noticed reg4 used three single-phase transformers but in GridAPPS-D it reflected in the star connection in "vgrp" and reg3 and reg2 regulators "vgrp" is Ii.

Could you clarify what the confusion is? reg4 is a three-phase regulator defined as three single-phase regulators. It means you can control the individual phases. Why are you particularly interested in vectorGroup?

This is not an issue with OpenDSS or CIM. The issue was within the optimization module for the VVO application.
