Chech the link. I complited it and also did fast decoupled power flow, Q limits cotrol by using Newton Raphson and using Crout's method.

this is the data file. you just try it for powerflow solution...

[Mohammad Yunus Ali]

Thanks for Data file

I need also Power flow solution code. Please help me.

[Walter Roberson]

Was this code copied from the MATLAB File Exchange? If so then the power flow code is there.

Answer 3

[sonu kumar]

any one can send me matlab code for optimal pmu placement by using integer linear programming for line outage and normal condition case. please help me. please send code on gmail [e-mail]

[Walter Roberson]

Yes, I recognize that as a project that gets assigned every couple of years, so there is someone in the world who has programmed it in the past. If you could find someone who had already programmed it, and you could convince them to share the code with you, you would be all set. It is possible.

However, in practice... it is probably going to take you longer to find someone who has already done the work and convince them to share the code with you, then it would take you to program it yourself.

Check out the link I send I completed it.

I used Newton Raphson to get it to converge and also used fast decoupled power flow analysis and Q limit control.

Let me know if you have questions.

Good luck!!
