This software contains two examples psotest.m and psotest.1.By running the programs
(psotest.m or psotest1.m) as they are in the default pso1 folder the economic dispatch problem
can be solved. The allocation minimum fuel cost and transmission losses are determined.
3. I am using the PSOt, particle swarm optimization toolbox for matlab developed by Prof Brian
Birge(Reference).My sincere thanks to him for the efficient toolbox.
% the data matrix should have 5 columns of fuel cost coefficients and plant limits.
% 1.a ($/MW^2) 2. b $/MW 3. c ($) 4.lower lomit(MW) 5.Upper limit(MW)
% This Example system is taken from the book Power System Analysis by Prof Haadi
Sadaat Example 7.8
%no of rows denote the no of plants(n)
global data B B0 B00
data=[0.008 7 200 10 85
0.009 6.3 180 10 80
0.007 6.8 140 10 70];
B=.01*[.0218 .0093 .0028;.0093 .0228 .0017;.0028 .0017 .0179];
B0=0*[.0003 .0031 .0015];
Pdef = [100 100000 100 2 2 0.9 0.4 1500 1e-6 5000 NaN 0 0];
F = 1.597481635286200e+003
Pl = 2.34255491258807
This solution is better than the solution given in the book
P=[33.4701 64.0974 55.1011];

ALL THE BEST
can anyone please send me eld solution with losses mailid email@example.com plzzz plzzzz plzzz
Can anyone help regarding Pdef. How is it working and how (in) is obtained.
This is really nice. Sir pls help to understand this code more. My email is firstname.lastname@example.org.
Thanks in advance
sir please can anyone help me regarding codes of this my mail id email@example.com
I need network reference used
Can we open the code in mobile?
What is the app required to open it?
I had a problem , your psotest.m at line 12
B0=0*[.0003 .0031 .0015]
isn't that B0=[0 0 0]?
I modify B0=[.0003 .0031 .0015] and test .
--> Solution likely, GBest hasn't changed by at least 1e-006 for 5000 epochs.
This solution is close to the original solution given in the book ex7.8 .
I had run the program given by you in the PSo tool box it is givin gcorrect results for the 3 bus data given by you but for other data
like the one below
data=[0.001562 7.92 561 100 600
0.00194 7.85 310 100 400
0.00484 7.97 078 50 200];
B=[0.000075 0.000005 0.0000075
0.001940 0.000015 0.0000100
0.004820 0.0000100 0.0000450];
actual answer for the economic load dispatch with losses is 6878 0r in that range but it is showing around 250000
kindly help me in this regard
necesito el codigo de programacion de (pso) en fortran o en otro programa
The penalty factor is chosen after verifying so many values.
Care is taken to get accuraccy.The accuracy ie sum(P)-Pl-Pd<1e-10.
Well-meaning but novice work. Author: (a) you are presenting *penalized* objective function, not the actual one, and (b) your penalty factor doesn't seem very high: check that the constraint is actually met.
