Hi,  
I’m a newbie learning Julia for optimal power flow formulation using convex optimization. I came across an example from Convex.jl documentation in here  
[https://jump.dev/Convex.jl/stable/examples/optimization\_with\_complex\_variables/power\_flow\_optimization/](https://jump.dev/Convex.jl/stable/examples/optimization_with_complex_variables/power_flow_optimization/)

In the example code the used “Data.mat” for the system parameters. I want to know how can I create the Data.mat file for any system provided in the Data folder of Matpower?  
Thank you.

Checkout [Home · PowerModels](https://lanl-ansi.github.io/PowerModels.jl/stable/). It has lots of tools for working with this sort of thing. It also has a lot of model formulations pre-built, so you don’t have to write your own.
