I just made one script for cas118 bus (put everything together !), so any information I need, appear on workspace. On Thu, Jan 12, 2012 at 6:49 PM, Arash Alimardani wrote: > So let me know! > > > On Thu, Jan 12, 2012 at 3:10 PM, morteza keshavarz < > mortezatal...@gmail.com> wrote: > >> Arash Ja

The Jacobian Matrix? or the derivative of Jacobian Matrix? I'm not positive, but I guess the problem formulation which matpower employes utilizes the derivative of it. I'll check it later for you. Tell me if you figure it out meanwhile. On Wed, Jan 11, 2012 at 11:24 AM, morteza keshavarz wrote:

Arash jan, one more thing and sorry for keep asking, Do you know How I can get Jacobian matrix after last iteration in state estimation? Many thanks, Morteza On Wed, Jan 11, 2012 at 2:14 PM, morteza keshavarz wrote: > Thanks for respond, So I should define new measurments for my case (118) > lik

Thanks for respond, So I should define new measurments for my case (118) like what they did in example test_se_14bus? Thanks again, On Wed, Jan 11, 2012 at 1:54 PM, Arash Alimardani wrote: > All right. First of all, that code is enhanced in the new version: 4.1. > The modified code is in "se"

2012-01-11 Thread Arash Alimardani
All right. First of all, that code is enhanced in the new version: 4.1. The modified code is in "se" folder. Secondly, you need to define the measurements locations and types and the measured data as input values in the new generic code. It works very well as long as your network is observable. R

Yes I do get answer with just runing runse('case14') with plots or other cases but ('case118') doesnt work and gives error. the matpower is 4.1. I am new in Matpower please corect me if I am doing wrong. Thanks, On Wed, Jan 11, 2012 at 12:00 AM, Arash Alimardani < arash.alimard...@ieee.org> wrot

What do you mean other cases work? Are you using version 4.1? by "runse" you mean "run_se"? Do you get answer by runse('case14') without definging the measurement parameters? On Tue, Jan 10, 2012 at 4:00 PM, morteza keshavarz wrote: > Hello, > > I can't do state estimation for case118 system and
