Review of power system linearization methods and a decoupled linear equivalent power flow model
2018 International Conference on Electronics Technology (ICET), 2018With the rapid development of power system, applications of classical AC power flow model are limited in the power system industry for its problems of nonlinearity, difficulty to converge and low computational efficiency, especially in large-scale systems. Thus the research of linear power flow is of great significance.

A Linear Model for AC Power Flow Analysis in Distribution Networks
IEEE Systems Journal, 2019The standard power flow (PF) equations are nonlinear, and their integration in the optimal PF (OPF) problem leads to a nonconvex hard-to-solve model. To attack the issue, this paper presents a linear PF model wherein real and imaginary parts of nodal voltages are variables.

Learning Optimal Power Flow Solutions using Linearized Models in Power Distribution Systems
2021 IEEE 48th Photovoltaic Specialists Conference (PVSC), 2021Solving nonlinear optimal power flow (OPF) problem is computationally expensive, and poses scalability challenges for power distribution networks. An alternative to solving the original nonlinear OPF is the linear approximated OPF models. Although, these linear approximated OPF models are fast, the resulting solutions may result in significant ...

Linear Power-Flow Formulation Based on a Voltage-Dependent Load Model
IEEE Transactions on Power Delivery, 2013The power-flow (PF) solution is a fundamental tool in power system analysis. Standard PF formulations are based on the solution of a system of nonlinear equations which are computationally expensive due to the iterations needed. On the other hand, distribution-system (DS) automation algorithms should be fast enough to meet real-time performance.
