In the recent years, nanostructured metal oxides have attracted a great interest as a promising anode materials for lithium-ion batteries. Co2.78Mn0.22O4 and Co2.82Mn0.18O4 nanoparticles belonging to Co3-xMnxO4 solid solution, were prepared by a sol-gel synthesis method employing alginate as a gelling agent. Characterized by X-Rays Diffraction (XRD) technique, the material crystallizes in the Fd-3m space group with the cubic spinel. As an anode materials for Li-ion batteries, Co2.78Mn0.22O4 exhibits high initial charge and discharge capacities of 723 and 429 mAh g-1, respectively. A reversible capacity of 418 mAh g-1 was maintained after 50 cycles at 180 mAg-1. Compared to Co2.82Mn0.18O4, Co2.78Mn0.22O4 with high Mncontent exhibits better performances.

In this work a load shifting for demand side management (DSM) strategy is developed. The strategy is based on an improved version of differential evolution DE, named Back Tracking Search Algorithm (BSA) is proposed in order to minimize the peak load demand and the total utility cost of three kinds of customers i.e. residential, commercial and industrial. The obtained simulation results are compared with those obtained using Particle Swarm Optimization (PSO) algorithm. This comparison highlights the effectiveness of BSA to handle a large number of different type devices.

In the last few decades, due to pollution increasing, scientists try to optimize and encourage renewable energies unit production. Fuel cell is a energy of the future that provides a safe, efficient and clean electrical energy. This paper presents the Proton Exchange Membrane Fuel Cell (PEMFC) static and dynamic model with the Perturb and Observe Maximum Power Point Tracker (P&O MPPT) method. Many advantages are considered to fuel cell, like low emissions, high efficiency, noiselessness and no vibration. The equivalent electrical circuit of the PEM fuel cell unit is developed and implemented in the software MATLAB/Simulink.

This paper presents a control for a Wind Farm System (WFS) based Permanent Magnet Synchronous Generator (PMSG) and Five Level Neutral Point Clamped converter (FL-NPC). Each wind turbine is equipped with a 2 MW-PMSG and an ac-dc converter. Only one dc-ac FL-NPC converts the dc-bus voltage to an appropriate ac voltage of WFS ac-bus. This paper adopts the Sliding Mode Approch (SMA) and the Vector Control Technique (VCT) to achieve the Maximum Power Tracking (MPT), the stable dc-link voltage, the control of active and reactive powers and the electrical network connection with a unity power factor. To evaluate the controller system abilities, simulation analyses are presented on a wind farm system with five PMSG connected to a grid with FL-NPC and under different operating conditions. The results demonstrate that the proposed techniques are capable to provide excellent control performances.

The objective of this work is to investigate magnetite storage performances using thermocline packed-bed single tank concept and confront it with the quartzite commonly used as TESM in this area. To achieve this purpose dual phase model for thermal energy storage (TES) is developed for describing heat and masse transfer inside the porous packed-bed contained in the storage tank. After validation, the developed model is used to simulate the thermal behavior discharging process and then to evaluate system performances by calculating discharge efficiency and storage efficiency for two TESMs: magnetite and quartzite coupled with Colza oil as a heat transfer fluid (HTF). This paper presents and discusses results of discharge efficiency and storage efficiency obtained for both TESM and highlights the impact of TESM choice on TES efficiency.

In this work, the thermo-hydraulic performance of shell and tube heat exchangers with segmental baffles (STHX) were investigated numerically for different baffle cuts. The heat transfer coefficient and the pressure drop have been considered as key parameters. These two parameters depend on the fluid flow path, which affected by the baffles characteristics (type, spacing, and the baffle cut). Baffles are used to improve heat transfer on the shell-side, but they increase the pressure drop, thus requiring a higher pumping power. This Phenomenon reduces the exchanger efficiency. For this purpose, the influence of different baffle cuts in a STHX on the heat transfer coefficient and the pressure drop were studied. The ratio $displaystyle frac {h_{s}}{Delta _{p}}$ has been taken as a criterion of performance evaluation and the commercial software Ansys-Fluent has been adopted to conduct the simulations. The results show that the heat transfer coefficient and the pressure drop are sensitive to the baffle cut selection. The maximum performance could be obtained with a baffle cut of 25%.

This work involves the synthesis and the characterization of CZTS layers. The films were prepared on ITO/glass substrate by one step electrodeposition technic without using the sulfurization step and compared with CZTS films prepared by sulfurization of electrodeposited Cu-Sn-Zn precursors. By adding Thiourea as a sulfur source and KSCN as a complexing agent, the electrodeposition process can give better results. Therefore, the effect of the sulfur source is investigated. The characterization of the absorber films was done by Cyclic Voltammetry (CV), ICP compositional analysis method, X-Ray Diffraction (XRD) and Scanning Electron Microscopy. The single step electrodeposition process is suggested to be better than the sulfurization and post-annealing treatment method.

In this paper, an efficient and fast MPPT power control of photovoltaic systems based on backstepping approach is presented. The proposed control scheme consists of two cascade loops; in the first loop, the auto-scaling variable step-size perturb and observe MPPT technique estimates the reference voltage of all electrical load values. The robust backstepping controller has been adopted to remove steady state oscillations in the second loop. Further, the performance of proposed control system has been analyzed through dSPACE DS-1104 experimental validation with Isofoton photovoltaic module under real climatic conditions at Biskra (Algeria) region. The results obtained by the used controller averred a good improvement.

within the framework of the sustainable development, the building sector seems an important component of the green economy programs in Morocco. Major research studies are undergoing in this field in order to highlight passive low-energy consumption construction techniques. And especially in Morocco, Energy efficiency in buildings is a national priority. Given the advantages of indigenous materials, academic institutions and industrials alike try to promote the development of new materials, especially the hygrothermal performance improvement of green building materials, that improve internal thermal comfort. Following this trend, hemp material is a good choice to respond to this demand and it is more and more used in construction. This paper comes in this order of ideas. And it aims to study and evaluate the thermal performance of hemp building envelope compared with two conventional construction alternatives. The building design of three case studies are based on the recommendations of Givoni and Mahoney methods. So as to compare between the performances of the three variants, we carried out a thermal simulation of the thermal behavior of each one by the dynamic thermal simulation software software DESIGN BUILDER considering a typical meteorological year (TMY) of Tangier, which refers to the second climatic zone in the thermal regulation for constructions in Morocco (RTCM).
