Hello,  
I’m new at Julia programming and currently I’m trying to familiarize myself with instruments to solve OPF and economic dispatch in Julia. I wrote this simple example

> <https://github.com/and2002/Julia_powerflow/blob/main/Simple_example>

Numerical data there is mostly random, since I only would like to have 100% working code for future experiments. But I faced with issue:

I validated components individually, seems that they are fine. But I cannot perform working simulation. Can anyone highlight any issue which causes that fault? Or refer me to simple working example.

Hello, Andrei

This is not a direct answer to your question, but Sienna has its own Slack channel: @NREL-Sienna. You will likely have better chances of getting a response there.

Take care.
