File Information
Description

This is a scaled down easy version of the state estimation module that is run in energy control centres. It has the following features:

(1) option to enter the weights for your measures
(2) an implementation of the weighted least square estimation

features missing:
(1) bad data recognition

MATLAB release MATLAB 6.5 (R13)

thanks to deepak krishnan, i had lot of computation on state estimation. each time i had to check it. thanks to u and ur program!

it is very good, but i'm very happy to get the WLS method with Hypothesis Testing instead of Normalized Residuals, for my final year project.
pleas help me, I'll so thankful.

i need it

Incomplete data,file shuntdata.txt has no details of the system bus or bus number and the value of the shunt.

- Uses clc and clear all
- no documentation provided
- inline comments given have limited value
- no vectorisation. It looks like the algorithms have been copied directly from a C or Fortran file
- usage of globals while not needed.

Although the program itself works, the programming needs serious improvements. Hence my 2-star rating

Too many errors, it can not work even for 2-bus system. However it is good for starting step to write a program on se.Thanks

in fact,this program have too many errors, it can not work at all.

good matlab coding although i not try yet. but i'm very happy to get the coding fro my final year project. Btw, Mr Deepak Krishnan, it is possible for me to study lini to line of the coding for the simulation especially in distribution part?

good to get this..
nice work

I've simulated the program to the 14 bus system test, using the data by power flow results. However, the estimator's results aren't good. They don't agree with the power flow results.

it is really nice. i want to know more about state estimation in power system using matlab

Hi Deepak
I was looking for an instant program to run a data set and BOOM!! find yours! Nice program but am gonna change quite a bit..sorry bout that.

It is very nice

hi i am from iitr. it is an excellent job what about distribution system state estimation?mail me

it is very good
