Best regards

Thank you, Mr. Lafifi,

I actually already based the second stage of my estimator based on that second link. I might also implement a non-linear generalized state estimator based on it, since there does not seem to exist any code for a generalized state estimator out there. The linear generalized state estimator, on the other hand, I had to build from scratch.

I will share the MATLAB code once I am finished with the project. Thank you again!

Hamed Shakouri G.

Hi Bard,

Did you finally solve your problem?

May I ask for your MatLab code?

This paper has suggested an algorithm for generalized observability:

Power System Topological Observability Analysis Including Switching Branches

IEEE TRANSACTIONS ON POWER SYSTEMS, VOL. 17, NO. 2, MAY 2002

It would be great if you can give me any positive feedback.

Thank you.

Hamed.

Hi Hamed

Attached to this comment, you can find the MATLAB code of WLS based state estimation for balanced power system.

Does anyone has state estimation code using WLS for a 3-phase unbalanced IEEE 13 bus system. Is there any relation with r/x ratio to its convergence. Please help me. Thank you in Advance.
