Optimal Power Flow With Power Flow Routers [PDF]
IEEE Transactions on Power Systems, 2017 Power flow routing is an emerging control paradigm for the dynamic control of electric power flows. In this paper, we propose a generic model of a power flow router (PFR) and incorporate it into the optimal power flow (OPF) problem. First, a generic PFR architecture is proposed to encapsulate the desired functions of PFRs.

The Fuzzy Power Flow Revisited
IEEE Transactions on Power Systems, 2005 The idea behind the first proposal of the fuzzy power flow (FPF) was to analyze the impact of the uncertainties in load and generation at the power flow level, when no statistical information is available. Further development of the field addressed the optimal power flow problem and the use of fuzzy methodologies to help planners of the composite ...

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.

Power Flow Control by Unified Power Flow Controller [PDF]
Engineering, Technology & Applied Science Research, 2019 The demand for electricity is increasing day by day and we have to produce more electrical energy to meet the load demands. Most of the experts prefer to extend the existing electrical networks over building the new network with greater costs. In this paper, the implementation of the flexible AC transmission systems (FACTS) devices in a simple ...

Distributed optimal power flow. [PDF]
PLoS One, 2021 Objective The objectives of this paper are to 1) construct a new network model compatible with distributed computation, 2) construct the full optimal power flow (OPF) in a distributed fashion so that an effective, non-inferior solution can be found, and 3) develop a scalable algorithm that guarantees the convergence to a local minimum.

Power Flow Control by Unified Power Flow Controller
Mehran University Research Journal of Engineering and Technology, 2020 The demand of energy usage is increasing rapidly and to meet the energy requirements, best possible transmission systems should be adopted to avoid energy losses in our transmission systems. In Pakistan’s WAPDA (Water & Power Development Authority) system, the rapid increase in load and less generation capacity has increased load shedding thought ...

Analysis of Power Flow in a Power Converter.
IEEJ Transactions on Industry Applications, 1996 Power converters have been widely used in many industrial applications. On the ac-side of such converters, the current is distorted because of the nonlinearity of the power devices even when the source voltage is sinusoidal. This leads that the power converter is regarded as a harmonic-current source.
