N2 - Optimal power flow (OPF) analysis in distribution systems has recently gained significant importance due to advancements and the high inclusion of distributed energy resources (DERs) in the power grid. Traditionally OPF analysis for power distribution networks has been solved with centralized techniques. However, the inclusion of DERs and an increased number of controllable devices makes the centralized OPF algorithms complex. Furthermore, the central management system of power networks is a vulnerable target for cyber-physical attacks. As the SOCP-OPF is computationally efficient, This article presents a SOCP-based distributed OPF (D-OPF) model for radial-type power system networks. The proposed D-OPF model divides the power network into several smaller areas, and the local optimal point information is shared with the connected areas. The proposed model is simulated and analyzed on different system power networks (i.e., IEEE 123-bus and 8500-bus), and compared with the base case and with DERs. It is observed that the proposed D-OPF model efficiently computes and produces an optimal global solution for radial-type distribution networks.
