A Study on the Strong Duality of Conic Relaxation of AC Optimal Power Flow in Radial Networks
arXiv:1807.08785
Abstract
This paper proposes a set of closed-form conditions to ensure the strong duality of second-order cone program (SOCP) formulation for AC power flow in radial power networks. In addition, numerical evaluations on IEEE 33-bus test networks and a real-world distribution network are performed to demonstrate the validity of the proposed conditions.
