A Network Restoration Model for Active Distribution Network with Coordinated Active and Reactive Power

Abstract

Reactive power is indispensable in power system operation in supporting bus voltage and meeting load demands. Therefore, a novel network restoration model is proposed in this paper for active distribution networks (ADN) with coordinated active and reactive power to restore more load after disaster-induced power blackout. This model considers the dispatch of ESS, network topology, active and reactive power of distributed generation (DG) resources, and static var compensators (SVCs) in the network restoration progress. While the linearized Distflow model is utilized to describe the power flow. The whole network restoration more is programmed using mixed-integer linear programming (MILP) to obtain a balance between computational efficiency and accuracy. The proposed active and reactive power model coordinated network restoration is demonstrated on the IEEE 33 bus testing system.
