Artificial neural network-based modeling for the prediction of heat and mass transfer coefficient of the adiabatic liquid desiccant system

This work, based on the data obtained from the literature reported by (Varela et al., 2018), aims to use the artificial neural network approach to predict the heat and mass transfer in a dehumidifier system, using lithium chloride as a liquid…

Wind data modeling and energy mapping of the wind potential in the city of Douala (Cameroun)

This work helps in the implementation of wind energy projects in the city of Douala. Wind data used (speed and direction) were collected from January 1, 2020, to December 31, 2020, at a height of 10m. The use of wind speed distribution laws allowed…

Analysis and Design of Modified Incremental Conductance-Based MPPT Algorithm for Photovoltaic System

This study discusses the design of the Maximum Power Point Tracking (MPPT) technique for photovoltaic (PV) systems employing a modified incremental conductance (IncCond) algorithm to extract maximum power from a PV module. A PV module, a DC-DC…

Use an artificial intelligence method (Machine Learning) for analysis of the performance of photovoltaic systems

The performance of a photovoltaic system depends on several parameters such as temperature, clouds, and the season, which makes the study of PV performance from monitoring databases very complex given the size of the information and the complexity of…

Experimental and CFD investigation of cavitation phenomenon in the distributor of a Banki-Michell Turbine

Cavitation is a physical phenomenon that often occurs in hydraulic machines such as pumps, valves, and turbines. Although the Banki-Michell turbine has been used for a long time in small hydropower, no study related to this phenomenon of cavitation…

Etude numérique de l’effet des générateurs de vortex longitudinaux sur le transfert thermique d’un écoulement laminaire traversant un micro-canal

We conducted, in this work, a three-dimensional numerical study of forced convection heat transfer of a laminar flow of water passing through micro-channels with and without longitudinal vortex generator, using the CFD code “Ansys- Fluent”. This work…

Fuzzy Logic PI controller based Direct Torque control of a Self-Excited Induction Generator through a three-level Rectifier

The main goal of this work is to control the terminal voltage of a Self-excitation induction generator (SEIG) that supplies autonomous load and is driven by a variable speed wind turbine. More advanced strategies of control have been suggested and…

Using two-dimensional graphene lenses to increase the effectiveness of solar panels

We aim to enhance the efficiency of solar panels by covering them with graphene lenses that collect and concentrate light rays onto the panels. The simulation was performed using the Monte Carlo method and provided precise results regarding the…

New graphical interface for Sizing PV systems

The objective of this work is to carry out a sizing program of the photovoltaic system isolated from the grid by determining the size of the subsystems that make up the photovoltaic generator, the batteries, the charge regulator and the…

Improved Fuzzy Logic MPPT Controller of Stand-alone WECS-based PMSG under Stochastic Wind Environment

This paper discusses the modeling and control of a Standalone WECS-based PMSG, the aim is to achieve an optimal operation of the studied WECS under a typically stochastic wind environment. The Maximum Power Point Tracking (MPPT) is guaranteed through…
