Robust Power Flow and Three-Phase Power Flow Analyses [PDF]
IEEE Transactions on Power Systems, 2019 Robust simulation is essential for reliable operation and planning of transmission and distribution power grids. At present, disparate methods exist for steady-state analysis of the transmission (power flow) and distribution power grid (three-phase power flow).

Linear AC Three-Phase OPF Model for Active Distribution Networks with Unbalanced ZIP Loads
Brazilian Archives of Biology and Technology, 2022 : Although nonlinear Alternating Current (AC) Optimal Power Flow (OPF) may provide more accurate results compared to linearized OPF models, many ACOPF problems are complex and may require high, sometimes infeasible, computational time.

A Three-Phase Power Flow Algorithm for Transmission Networks: A Hybrid Phase/Sequence Approach
IEEE Access, 2021 In this paper, the three-phase generalization of a single-phase power flow (named PFPD) developed by the first author is presented. This three-phase formulation is chiefly conceived for HV/EHV transmission network applications, but it preserves a general
