Optimal Integration of Distributed Generators into DC Microgrids Using a Hybrid Methodology: Genetic and Vortex Search Algorithms
(2022)
This paper addresses the problem of optimal location and sizing of distributed generators (DGs) in direct current (DC) grids. To solve it, we propose an optimization approach with an objective function that aims to reduce ...
Optimal Allocation and Sizing of PV Generation Units in Distribution Networks via the Generalized Normal Distribution Optimization Approach
(2022)
The problem of optimal siting and dimensioning of photovoltaic (PV) generators in medium-voltage distribution networks is addressed in this research from the perspective of combinatorial optimization. The exact mixed-integer ...
On the Optimal Reconfiguration of Radial AC Distribution Networks Using an MINLP Formulation: A GAMS-Based Approach
(2022)
This paper addresses the problem of the optimal reconfiguration of medium-voltage distribution networks by proposing a mixedinteger nonlinear programming (MINLP) model. The objective function of this optimization model is ...
Optimal integration of D-STATCOM in distribution grids for annual operating costs reduction via the discrete version sine-cosine algorithm
(2022)
This paper deals with the problem of the optimal placement and sizing of distribution static compensators (D-STATCOM) in electrical distribution networks to reduce the total annual operative costs associated with the total ...
On the Convergence of the Milky Way and M31 Kinematics from Cosmological Simulations
(2022)
The kinematics of the Milky Way (MW) and M31, the dominant galaxies in the Local Group (LG), can be used to estimate the LG total mass. New results on the M31 proper motion have recently been used to improve that estimate. ...
On Board Neuro Fuzzy Inverse Optimal Control for Type 1 Diabetes Mellitus Treatment: In-Silico Testing
(2022)
Type 1 Diabetes Mellitus (T1DM) is one of the most adverse diseases in the modern era; its treatment is mainly based on exogenous insulin injections. The scientific community has formulated strategies to improve insulin ...
Optimal Power Dispatch of DGs in Radial and Mesh AC Grids: A Hybrid Solution Methodology between the Salps Swarm Algorithm and Successive Approximation Power Flow Method
(2022)
In this paper, we address the problem of the optimal power dispatch of Distributed Generators (DGs) in Alternating Current (AC) networks, better known as the Optimal Power Flow (OPF) problem. We used, as the objective ...
Equivalence of categories of simple Lie algebras in positive characteristic
(2022-07-18)
In this paper we first study some properties of the finite-dimensional simple restricted Lie algebras. In the literature is found a one-to-one correspondence between them and finite-dimensional simple Lie algebras over a ...
Effects of Different Concentrations of Arsine on the Synthesis and Final Properties of Polypropylene
(2022-07-31)
This article studies the effects of arsine on the synthesis and thermal degradation of 4 sam ples of virgin polypropylene (PP-virgin) and proposes reaction mechanisms that allow understanding
of its behaviour. Different ...
Impact of Traces of Hydrogen Sulfide on the Efficiency of Ziegler–Natta Catalyst on the Final Properties of Polypropylene
(2022-09-19)
Sulfur compounds are removed from propylene through purification processes. However,
these processes are not 100% effective, so low concentrations of compounds such as H2S may be
present in polymer-grade propylene. This ...
