A Comparative Analysis of Two Loosy DC Optimal Power Flow

Classic DC power flow and Generalized Generation Distribution Factors (GGDF) are used for modeling the transmission network constraints in a DC optimal power flow (OPF). The first method is known for its simplicity, accuracy, and robustness, and the second for its ability to express transmission power flows as a function of the power generation with less equality constraints. This paper compares the two formulations by testing them on a PJM 5-bus system and an IEEE 57-bus system including transmission losses, using different commercial optimization solvers.
