Linear Probabilistic Power Flow for Islanded Microgrids
2020 International Conference on Probabilistic Methods Applied to Power Systems (PMAPS), 2020The problem of power flow in islanded operation of microgrids is more complex than in interconnected mode due to the absence of a slack bus. In addition, the power flow must consider uncertainties in a probabilistic framework. Probabilistic power flow has a high computational cost due to the need to assess a large number of states and the use of ...

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.

A linear programming approach to distribution Power Flow
2017 6th International Conference on Clean Electrical Power (ICCEP), 2017The modern Distribution Systems (DS) require for accurate and fast Power Flow (PF) algorithms as a basis for other DS applications. Almost all decisions are taken based on accurate PF results and, possibly, they have to be taken in real time. In this paper, a new PF algorithm based on a linear programming approach is proposed.

Measurement-based Optimal Power Flow with Linear Power-flow Constraint for DER Dispatch
2019 North American Power Symposium (NAPS), 2019This paper proposes a measurement-based method to obtain optimal power-flow (OPF) solutions that optimize distribution-system operations by dispatching active- and reactive-power outputs of distributed energy resources (DERs). Central to the proposed method is the estimation of a linear power-flow model from synchronized voltage and power-injection ...

Fast power system analysis via implicit linearization of the power flow manifold
2015 53rd Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2015In this paper, we consider the manifold that describes all feasible power flows in a power system as an implicit algebraic relation between nodal voltages (in polar coordinates) and nodal power injections (in rectangular coordinates). We derive the best linear approximant of such a relation around a generic solution of the power flow equations.

Wave propagation in linearized shallow flows of power-law fluids
Advances in Water Resources, 2018Abstract A depth-averaged model with a power-law rheology, usually adopted for debris flow of fine sediment-water mixtures, is analytically studied, considering the complete (Full Dynamic Model) and the simplified momentum equations, known as Kinematic, Diffusion, and Quasi-steady Models.

A frequency- domain inequality for stochastic power flow in linear networks
IEEE Transactions on Circuits and Systems, 1984This paper addresses the frequency-domain characterization of stochastic signals in linear time-invariant distributed networks. A new general relation is derived. The average power flow at each frequency from one source to another through a lossless coupling network is shown to obey an inequality related to the second law of thermodynamics. The sources
