A sample-based approach for computing conservative linear power flow approximations
Electric power systems research, 2022 —Non-convexities induced by the non-linear power flow equations challenge solution algorithms for many power system optimization and control problems. Linear approximations are often used to address these challenges by trading off modeling accuracy for ...

Data Based Linear Power Flow Model: Investigation of a Least-Squares Based Approximation [PDF]
IEEE Transactions on Power Systems, 2020 Linearization of power flow is an important topic in power system analysis. The computational burden can be greatly reduced under the linear power flow (LPF) model while the model error is the main concern.

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.

Log(v) 3LPF: A Linear Power Flow Formulation for Unbalanced Three-Phase Distribution Systems
IEEE Transactions on Power Systems, 2021 In this work, we introduce Log(v) 3LPF, a linear power flow solver for unbalanced three-phase distribution systems. Log(v) 3LPF uses a logarithmic transform of the voltage phasor to linearize the AC power flow equations around the balanced case.
