On the Existence of the Power Flow Solution in DC Grids With CPLs Through a Graph-Based Method
(2020-08-27)
This brief explores the formulation of the power flow problem in DC grids with a classical incidence matrix through a graph-based formulation. This corresponds to a compact representation of the conventional backward/forward ...
On the numerical analysis based on successive approximations for power flow problems in AC distribution systems
(2020-10)
This paper proposes a new power flow formulation for alternating-current distribution networks for radial and mesh topologies. This formulation corresponds to a successive approximation based on a modification of the ...
Optimal power flow studies in direct current grids: An application of the bio-inspired elephant swarm water search algorithm
(Institute of Physics Publishing, 2019)
Colombian power system is experienced important changes due to the large scale integration of renewable power generation based on solar and wind power; added to the fact that direct current networks have taken important ...
Modeling of dynamic mass coupled system with Runge-Kutta fourth order
(Institute of Physics Publishing, 2019)
This paper shows the mathematical modeling process of a mechanical system of masses coupled by two springs and a shock absorber. The process of capture of movement of the mass system coupled with springs was done with ...
α-bandlimited diffuser in fractional Fourier optics
(SPIE, 2016)
We propose a method for calculating appropriate α-band limited diffusers using the fractional Fourier transform. In order to do this, we implement a method for performing a numerical interpolation in the fractional Fourier ...
Triangular Matrix Formulation for Power Flow Analysis in Radial DC Resistive Grids With CPLs
(2019-07)
This brief briefly addresses the problem of power flow solution for direct-current (dc) networks with radial configuration and constant power loads (CPLs). It proposes a novel iterative method based on the upper triangular ...
Integration of energy storage systems in AC distribution networks: Optimal location, selecting, and operation approach based on genetic algorithms
(Elsevier Ltd, 2019)
This paper presents a method to find the optimal location, selection, and operation of energy storage systems (ESS- batteries-) and capacitors banks (CB) in distribution systems (DS). A mixed-integer non-linear programming ...
On the Matricial Formulation of Iterative Sweep Power Flow for Radial and Meshed Distribution Networks with Guarantee of Convergence
(2020-08-21)
This paper presents a general formulation of the classical iterative-sweep power flow, which is widely known as the backward–forward method. This formulation is performed by a branch-to-node incidence matrix with the main ...
A model for the simulation of the chill block melt spinning (CBMS) process using OpenFOAM®
(Elsevier Masson SAS, 2020)
This work shows the results of a numerical model developed to simulate the CBMS technique for the production of the Fe78Si9B13 metallic magnetic ribbons for application in electronics. The model proposes a numerical ...
Numerical Simulations of a Polydisperse Sedimentation Model by Using Spectral WENO Method with Adaptive Multiresolution
(World Scientific Publishing Co. Pte Ltd, 2016)
In this work, we apply adaptive multiresolution (Harten's approach) characteristic-wise fifth-order Weighted Essentially Non-Oscillatory (WENO) for computing the numerical solution of a polydisperse sedimentation model, ...
