Convex Relaxation of Optimal Power Flow—Part I: Formulations and Equivalence
Convex Relaxation of Optimal Power Flow—Part I: Formulations and Equivalence
This tutorial summarizes recent advances in the convex relaxation of the optimal power flow (OPF) problem, focusing on structural properties rather than algorithms. Part I presents two power flow models, formulates OPF and their relaxations in each model, and proves equivalence relations among them. Part II presents sufficient conditions under …
