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
%no of rows denote the no of plants(n)

[OUT]=pso_Trelea_vectorized('f6',n,1,ran,0,Pdef);
out=abs(OUT)
P=out(1:n)
[F Pl]=f6(P')
The results
P =

Pl = 2.34255491258807
This solution is better than the solution given in the book
