Congestion management in deregulated environment using Generator Rescheduling

my project is to minimize the rescheduling cost of the generators such that the congestion gets cleared at a least cost

F=min(summation(Cg*(delPg)*delPg))

where Cg price bids submitted by gencos and delPg is the real power adjustment of the generators. How to make code to obtain optimized power output of Generators? can anyone help me with this?

There must be more to the equation than you have described, or else the solution would be to let delPg be 0.

Is delPG a matrix of fixed values, and does (delPg)*delPg indicate matrix multiplication ?

[sumit verma]

solution is let delpg be 0. please provide the coding.
