Convex Relaxation of Optimal Power Flow, Part I: Formulations and Equivalence

Understand

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 which the convex relaxations are exact.
