The nonlinear and nonconvex nature of ac power flow challenges the analysis and
optimization of unbalanced distribution networks. To tackle this issue, this paper proposes …

In this work we introduce PowerModelsDistribution, a free, open-source toolkit for
distribution power network optimization, whose primary focus is establishing a baseline …

This paper considers multiphase unbalanced distribution systems and develops
approximate AC power-flow models wherein voltages, line currents, and powers at the point …

This paper proposes a three-phase unbalanced linear power flow model and provides a set
of comparisons to show the effectiveness of the model when compared to full AC power flow …

The distribution system is experiencing a paradigm shift in its operation with the integration
of distributed energy resources (DERs). The integration of DERs is increasing at a rapid …

This paper presents a linear-convex formulation for the optimal power flow (OPF) in three-
phase unbalanced power distribution networks considering mixed wye and delta-connected …

With high integration of distributed energy resources (DERs), modern distribution networks
are subject to optimal power flow (OPF) analysis. Conventional non-linear and linear OPF …

A realistic and practicable modeling of unbalanced distribution networks (DNs) is the
missing link in most studies undertaken in these networks, eg, optimal power flow (OPF) …

Modern distribution systems are changing from passive load serving networks to active load
and generation-inclusive networks. Accurate distribution systems modeling is critical for …

This paper proposes a new linear power flow model for distribution system with accurate
voltage magnitude estimates. The new model can be seen as a generalization of …
