Sir Mahesh Pandya... Did you get a solution to your Question?If so.. May I please know it Sir.. 

Hello there, I think you can in first step reviewing Bat algorithm (demo) in Matlab.  

This is a short demo for the popular, nature-inspired/metaheuristic,

bat algorithm (BA), which can deal with nonlinear, global optimization problems.

Bat algorithm has the advantages of simplicity, flexility and stability.

It can also automatically switch from global exploration to

local exploitation by fine-tuning its parameters: A and r.

Dear Mahesh Pandya

A helpful link

Can you please assist with wind-thermal economic dispatch MATLAB codes for Multi-objective/single objective. Emission and fuel cost minimization. It can have any constraints.

you can check this, but it is not very useful for advanced works:
