Linear programming for economic dispatch

Hi guys, i have this two generator equations and i want to use LINPROG to find the optimal power genion for each unit and get the lambda value given an equality constraint of p1+p2=220MW.

clc; clear all; close all;

load=220;

f=[0.2 3 0.175 3];erat

aeq=[1 1 1 1];

beq=load;

%lb=[0 0]

%ub=[500 0]

[x,fval]=linprog(f,[],[],aeq,beq,[],[])

This is what i have tried but its not working.

Thanks

Hello Divyesh,

Use Quadprog instead of linear Prog.

is the objective function convert it to form where , to find with respect to . Similiary do the same of .

1. Incremental cost of two power plant units with minimum and maximum power generation between 30MW to 300MW are as follows:

• Find the economic power dispatch between these units at load 500MW.
• Verify your answers using matlab. Show the code and the results.
