Simultaneous Minimization of Fuel Cost and Voltage Deviation (Fcost_VD)
Though the minimization of total generation fuel cost may give a feasible solution, the voltage profile may not be acceptable. Therefore, in the present case a twofold objective function is taken in consideration to minimize the fuel cost and improve voltage profile by minimizing the load bus voltage deviations from 1.0 p.u. The objective function can be expressed as

where wV is a weighting factor for voltage deviation.
