Pyramidal approximation for power flow and optimal power flow [PDF]
IET Generation, Transmission & Distribution, 2020 Power flow equations (PFEs) are the fundamental of power flow (PF) calculations and optimal PF (OPF) for power system analysis, but existing PFEs suffer from the trade‐off among various requirements in practice. This study presents a novel pyramidal approximation (PA) for PF and OPF.

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.

Weather-Based Optimal Power Flow With Wind Farms Integration [PDF]
, 2016 In conventional optimal power flow (OPF), parameters of electrical components such as resistance and thermal ratings of the overhead lines, are assumed to be constant despite the fact that they are strongly sensitive to the weather effect (e.g ...

Decomposed Iterative Optimal Power Flow with Automatic Regionalization
Energies, 2020 The optimal power flow (OPF) problem plays an important role in power system operation and control. The problem is nonconvex and NP-hard, hence global optimality is not guaranteed and the complexity grows exponentially with the size of the system ...
