Abstract:

Abstract—Loss minimizing generator dispatch profiles for
power systems are usually derived using optimization techniques.
However, some authors have noted that a system’s KGL matrix
can be used to analytically determine a loss minimizing dispatch.
This letter draws on recent research on the characterization of
transmission system losses to demonstrate how the KGL matrix
achieves this. A new proof of the observed zero row summation
property of the YGGM matrix is provided to this end.

Electrical power system calculations rely heavily on the Y_{bus} matrix,
which is the Laplacian matrix of the network under study, weighted by the
complex-valued admittance of each branch. It is often useful to partition ...

In this paper we are concerned with the solution of Compressed Sensing (CS) problems where the signals to be recovered are sparse in coherent and redundant dictionaries. We extend the primal-dual Newton Conjugate Gradients ...

This paper extends the classical Samuelson multiplier–accelerator model
for national economy. Actually, this new modeling structure removes the basic shortcoming of the original model producing stable business cycles when ...

In this article, we focus on a generalized problem of linear non-autonomous fractional nabla difference equations. Firstly, we define the equations and describe how this family of problems covers other linear fractional ...

A model for the spreading of online information or ‘memes’ on multiplex networks is introduced and
analyzed using branching-process methods. The model generalizes that of (Gleeson et al 2016 Phys.
