In this paper, a new modified variable step P&O maximum power point tracking algorithm using Proportional-Integral-Derivative controller tuned by particle swarm optimization is proposed. The classical fixed step P&O algorithm has good performances due to its simplicity and easy implementation; however, failing and inefficiency especially in case of rapidly changing atmospheric conditions, as well as oscillation around the maximum power point decreasing by the way the convergence speed are the main drawbacks. To solve these drawbacks, a new variable step P&O algorithm using Particle Swarm Optimization based Proportional-Integral- Derivative controller is presented. A theoretical analysis of the proposed algorithm has been provided using a boost converter connected to a Solarex MSX-60 model. Analysis and comparison between the classical fixed step P&O and that developed Particle Swarm Optimization variable step are presented. The efficiency and improvements of the proposed algorithm in transient, steady-state and dynamic responses, related to ripple, overshoot and response time, especially under rapidly changing atmospheric conditions have been demonstrated.]]>

The present work deal with a comparative study of two kinetics models of ethanol conversion by steam reforming for pure hydrogen generation in a Pd-Ag based membrane reactor. For this purpose, a mathematical model describing the reaction and separation phenomena that take place simultaneously in the membrane reactor was developed. The numerical solution of the set of differential equations constituting the obtained model allows us to quantify the process performance over both and catalysts. According to the obtained results, it was found that the performance of the ethanol steam reforming process depends strongly on the catalyst nature. In addition, the process's strongly sensitive to the used operating conditions, especially hydrogen partial pressure in permeate and in reaction sides, in which a good correlation and a synergistic effect between these parameters could be established. Under the optimal operating conditions, the quantity of hydrogen recovered when using the is three times greater than that obtained by using the catalyst.]]>

L’effet de la composition de l’eau influe significativement sur la tension indiquant le rôle des sels minéraux pour le système électrochimique et pour la vitalité de la plante. Le processus de la photosynthèse est lié directement à l’influence de la lumière et le pH du sol augmenterait la tension produite. La plante Bromelia Vriesea présente un outil biologique intéressant pour la production de bioélectricité en optimisant les conditions physico-chimiques (pH du sol, lumière, type de plante) et électrochimiques (matériaux d’électrodes).]]>

Le fait d’obtenir cette information, nous permettra de faciliter la gestion du réseau. Afin d’y parvenir, des modèles de prévision numériques du temps à courte échéance ont été utilisés afin de prévoir les profils verticaux de l’atmosphère en l’occurrence le model 'WRF' {Weather Research and Forecasting}. Ces données serviront également comme données d’entrée pour le modèle de transfert radiatif 'libRadtran', nécessaires pour déterminer les composantes de l’éclairement solaire par ciel quelconque (directe, diffuse et globale). Les valeurs de l’éclairement solaire seront obtenues sur des points de Grid (mailles).]]>

Geothermal potential in Algeria]]>
Sustainable construction]]>
At present, the convergence between the scarcity of fossil resources and their threat to the environment leads to considering renewable energies as an alternative in the production of heat in countries privileged by their climate and geology. These sources of energy are deemed almost inexhaustible, omnipresent, stable and clean. The Algerian construction sector is the most energy-intensive compared to other economic sectors. This unbounded energy consumption can be corrected with a more economical design of passive buildings to finally work towards buildings with net zero energy consumption. In this work, the emphasis will be on the possibility of combining geothermal energy with solar thermal power in order to exploit them in a sustainable construction project. The integration of solar thermal in a construction project has already been the subject of large studies and is still under development; therefore, we will focus, as a first step, on the integration of geothermal energy in a sustainable building.]]>

Renewable energies in Burundi]]>
Cet article s’inscrit dans le cadre d’une évaluation de l’impact de l’électrification des zones rurales par les micro-réseaux, à base des systèmes photovoltaïques autonomes, sur l’économie Burundaise. Le travail se focalise sur une étude de l’utilisation d’un système comportant des panneaux photovoltaïques (PV) associés à des périphériques de stockage (batteries). Dans ce travail, l’approche proposée est la régression aux moindres carrés, sous les hypothèses de Gauss-Markov. L’estimateur aux moindres carrés est le meilleur estimateur non biaisé. Les résultats obtenus sont satisfaisants et nous montrent un impact positif de l’électrification des zones rurales par les micro-réseaux, à base des systèmes photovoltaïques autonomes, sur l’économie Burundaise.]]>

Virtual Flux Estimation]]>
This paper deals with the control aspect of the brushless doubly fed induction generator, 'BDFIG' incorporating in a wind energy conversion system, 'WECS'. The control process may divide in two main parts control of machine side converter, MSC' and grid side converter, 'GSC'. Control process adopts direct power control, DPC approach thanks to its robustness and implementation simplicity direct power control permits decoupled regulation for active and reactive powers and as well pretty good robustness and performance during transient and steady state operation without PI regulators and rotating coordinate transformations. The regulation of power flow toward supply network via stator is performed using conventional direct power control at level the machine side converter where the active power reference signal is tuning depending to the output of the MPPT unit and the reactive power reference signal is set to zero to ensure unity power factor operation. Meanwhile, control of power flow between grid and grid side converter, 'GSC' is done using improved direct power control based virtual flux and Second order generalized integrator - frequency locked loop, 'SOGI-FLL' estimator in order to estimate frequency and angular position of voltage grid vector and as well power flow has been analysed during various operation conditions, 'synchronous, sub synchronous and super synchronous speeds'. The obtained simulation results show satisfactory system operation in terms of robustness and optimum power tracking behaviour and good steady state stability and finally reasonable settling time during transients.]]>
