Joint Beam and Power Control for Millimeter-Wave Multi-Flow Multi-Hop Networks [PDF]

open access: yesIEEE Communications Letters
This letter investigates the joint beam and power control in multi-flow multi-hop networks with millimeter-wave (mmWave) directional transmissions. To guarantee fairness among multiple data flows, an optimization problem is formulated to maximize the ...

Linear programming based optimal power flow using second order sensitivities [PDF]

open access: yes, 1995
For the electric railway traction in Sweden, a system of 130 kV transmission lines connected parallel to the contact lines is being build. Within this system, the generation costs differs only slightly between different nodes with power injections.

Optimal Power Flow for Three-phase Unbalanced Active Distribution Networks with Delta Connections

IEEE ANDESCON, 2022
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 loads. The present approach describes an optimization model based on Taylor’s

Distributed OPF for PET-Based AC/DC Distribution Networks With Convex Relaxation and Linear Approximation

IEEE Transactions on Smart Grid, 2022
A power electronic transformer (PET) can flexibly regulate the power flow of a network and facilitate the integration of distributed energy resources via AC/DC networks. With the continuous expansion of the scale of multiregional interconnection networks,

Linear Approximation of Optimal Reactive Power Flow Model for Inverter-based Power Systems

2026 11th Asia Conference on Power and Electrical Engineering (ACPEE)
To establish a low-carbon power system, high penetration of inverter-based generators (IBGs) driven by renewable energies is integrated into the grid, which presents a profound transition in optimal reactive power flow (ORPF) model.

Theoretical analysis on hydrodynamic performance for a dual-chamber oscillating water column device with a pitching front lip-wall

Energy, 2021
For the sake of extracting wave energy over a broader range of wave frequencies, dual-chamber OWC devices are more beneficial than the single-chamber one.
