Genetic Algorithm Solution to Economic Dispatch

This program solves the economic dispatch problam using MATLAB genetic algorithm toolbox

Description

This software contain two examples gatest.m and gatest.1.By running the programs as they are in the default folder. The allocation minimum fuel cost and transmission losses can be determined.

% The Example system is taken from the book Power System Analysis by Prof Haadi Sadaat Example 7.8
% 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)
%no of rows denote the no of plants(n)

A homework project of little benefit to anybody with access to GA Toolbox docs. 'Economic dispatch problem' is apparently a scheduling one; there are several submissions on FEX (including some by Yi Cao) addressing it.
