Abstract

This paper proposes a fault recovery strategy for AC/DC hybrid distribution networks (HDNs) to restore critical loads in face of extreme events, in which the flexible topology with islanding partition is integrated for multi-source synergy. The island partition-based recovery model maximizes the active power of restored loads as the objective function while considering the power flow constraints, radial topology constraints, and multiple sources’ constraints. Then, the proposed model is transformed into a mixed-integer second-order cone programming (MISOCP) formulation by linearization and convex relaxation, which can be solved effectively. Finally, the effectiveness of the proposed service restoration method is validated on a modified IEEE 33-node AC/DC test feeder.
