Re: PF and OPF did not converge

Dear Charalambos:

To begin with, you have a load of 894.31 MW (computed with sum(mpc.bus(:,PD)) and a total generation capacity of 30 (computed with sum(mpc.gen(:, PMAX)) . Your slack generator has PMAX specified as zero. And it seems to me that many of your branch reactances are way too high to allow a poser flow solution with a total load of 8.1 p.u. ,

Subject: PF and OPF did not converge

Dear Ray,

I am trying to run PF and OPF for the following case but every time it doesnt converged the system. Please can you give me any advice??

The system consist 62 buses, 23 transformers, 8 photo voltaic plants and 1 Natural gus generator.

I consider all the buses as Type 1(PQ) and the natural gas generator as Type 2 (PV). The real power demand (Pd) for the photo voltaic plants i gave them a negative sign.

function mpc = IsleExample3()
