Optimizing Biodiesel Production from Waste Cooking Oil Using Genetic Algorithm-Based Support Vector Machines
(MDPI, 2018-11-01)
The ever increasing fuel demands and the limitations of oil reserves have motivated research of renewable and sustainable energy resources to replace, even partially, fossil fuels, which are having a serious environmental ...
Using Genetic Algorithms With Multi-Objective Optimization To Adjust Finite Element Models Of Welded Joints
(MDPI, 2018-04-02)
To ensure realistic results when modeling welded joints using the finite element method (FEM), it is essential to appropriately characterize the thermo-mechanical behavior of the elastic-plastic Finite Element (FE) models. ...
A Real-Time Sliding Mode Control for a Wind Energy System Based on a Doubly Fed Induction Generator
(MDPI, 2014-10)
In this paper, a real time sliding mode control scheme for a variable speed wind turbine that incorporates a doubly feed induction generator is described. In this design, the so-called vector control theory is applied, in ...
Influence of Cryogenic Treatment on Wear Resistance and Microstructure of AISI A8 Tool Steel
(MDPI, 2018-12)
The effects of deep cryogenic treatment (DCT) on the wear behavior of different tool steels have been widely reported in the scientific literature with uneven results. Some tool steels show a significant improvement in ...
Electric Vehicle into the Grid: Charging Methodologies Aimed at Providing Ancillary Services Considering Battery Degradation
(MDPI, 2019-06-25)
The necessity of transport electrification is already undeniable due to, among other facts, global Greenhouse Gas (GHG) emissions and fossil-fuel dependency. In this context, electric vehicles (EVs) play a fundamental role. ...
Analysis of the Current Electric Battery Models for Electric Vehicle Simulation
(MDPI, 2019-07-18)
Electric vehicles (EVs) are a promising technology to reduce emissions, but its development enormously depends on the technology used in batteries. Nowadays, batteries based on lithium-ion (Li-Ion) seems to be the most ...
Aspects to take into account in the application of mechanical calculation to high temperature low sag conductors
(The Institution of Engineering and Technology, 2010-05)
Reconductoring with high temperature low sag (HTLS) conductors is an alternative to the traditional uprating methods. The obtained rating increase depends on the mechanical and thermal behaviour of the conductor. In this ...
Review of dynamic line rating systems for wind power integration
(Elsevier, 2016-01)
When a wind power system is connected to a network point there is a limit of power generation based on the characteristics of the network and the loads connected to it. Traditionally, transmission line limits are estimated ...
Operating Point Optimization of a Hydrogen Fueled Hybrid Solid Oxide Fuel Cell-Steam Turbine (SOFC-ST) Plant
(MDPI, 2013-09-30)
This paper presents a hydrogen powered hybrid solid oxide fuel cell-steam turbine (SOFC-ST) system and studies its optimal operating conditions. This type of installation can be very appropriate to complement the intermittent ...
Gain Scheduling Control of an Islanded Microgrid Voltage
(MDPI, 2014-07)
The aim of this research study has been to design a gain scheduling (GS) digital controller in order to control the voltage of an islanded microgrid in the presence of fast varying loads (FVLs), and to compare it to a ...
