Simultaneous Minimization of Fuel Cost and Power Loss (Fcost_Ploss)
In this case, the minimization of the system fuel cost and real power loss are approached. These two competing objectives are optimized simultaneously with the proposed algorithm. The objective function balances the two objectives in such a way that one objective should not dominate the other. The new objective function may be expressed as

where Ploss is the total system real power loss andwPloss is the weighting factor for the real power loss, to be chosen by the user.
