Comparative Study of Optimal Power Flow Solution using DC and Generalized Generation Distribution Factor Formulations

This paper proposes the use of Generalized Generation Distribution Factors (GGDF) to model network constraints in the optimal power flow (OPF). In this formulation, the nodal balance equality constraints are modeled using one equality constraint, and the transmission network constraints have been modeled using the GGDF. This formulation is compared vs classical DC formulation. Several popular commercial software are used to evaluate the computational efficiency of the OPF formulations. Both formulations are validated and tested on the PJM 5-bus and IEEE 14-bus systems.
