To solve the load shedding problem in the Comoros in a targeted rural area (Mbeni in the island of Ngazidja), I recommend the micro-grid system based on a renewable energy source with hydrogen storage. It has been almost two decades since the power generation company has been able to feed a large part of the Comorian population. This is due to the obsolescence of the production equipment of the electricity company, and the fact that the cost of the raw material (diesel) is very high compared to the cost of living of the Comorian population. The electricity company is struggling to cope with the increase in demand, which is about 5.1% per year. This increase in demand and the obsolescence of the equipment cause many load shedding. To combat this appalling plague, a feasibility study of the microgird system based on a renewable energy source with hydrogen storage seems entirely conceivable. In this article, solutions for electrifying rural areas in Comoros were designed and analyzed using Hybrid Renewable Energy Optimization (HOMER) with hydrogen storage.This system consists of:a photovoltaic generator, a wind turbine, an electrolyser, a fuel cell, a storage tank in the form of hydrogen.

In this work, we compare the structural, electronic and optical properties of the three most common phases (wurtzite, zinc blende, rocksalt) of ZnS by adopting the Density Functional Theory (DFT) implemented in the Wien2k code. We used the generalized gradient approximation (GGA-PBE) and the modified Becke-Johnson potential (TB-mBJ) to calculate the various properties. This study shows that ZnS phase wurtzite is thermodynamically stable, the phase blende and wurtzite present the same electronic and optical properties. These results are in agreement with experimental data.

This paper develops a multi-objective energy management strategy for power dispatch of the grid-tied photovoltaic (PV)-wind turbine (WT)-battery system to supply an industrial load. The aim is to minimize electricity cost while participating to the Time of Use Demand Side Management program, which is an important control parameter in this model to assist utility companies to control the grid in terms of security, reliability and efficiency. This issue is considered as a deterministic problem and solved using linear programming. In order to demonstrate the effectiveness of the proposed approach, comparison with other methodology of control is carried out. Simulation results show that the developed control reduces the operational cost of the hybrid system and allow consumers to benefit from a significant income by maximizing the selling power to the utility grid.

This article presents the design of a solar controller used in photovoltaic systems to protect the battery against the phenomenon of overcharging and deep discharge. In addition to the protection function, this controller ensures the tracking of the maximum power point (MPPT) and allows the photovoltaic generator to deliver its maximum power whatever the variation of the climatic conditions (irradiation and temperature), a study and comparison of a classical control (perturb and observe “P&O”) with an intelligent control (artificial neural networks “ANN”) was presented. Simulations performed under MATLAB and SIMULINK allow illustrating the advantages and disadvantages of each technique to be drawn.

Organic solar cells are based on a couple of organic materials, one is called electron donor and the other electron acceptor. Usually the acceptor is the fullerene. However if it is an efficient electron conductor, it absorbs weakly the light and its contribution to the current is small. Therefore, in the present work we study couples where the acceptor is SubPc, AlPcCl, DTPMM or DBP. These molecules have been chosen as electron acceptor because their band structure is compatible with such use. The study shows that the band offset value between the electron donor and the electron acceptor must be higher than the exciton energy, whatever the distribution between the bands. Moreover, it is shown that, if a sufficient band offset value is necessary, it is also necessary that the molecule proposed as electron acceptor must have a sufficient electron mobility, i.e., the molecule must be ambipolar. On the other hand the electron donor layer must be smooth and must exhibit a sufficient hole mobility.

This work presents a control strategy for wind power generation system based on PMSG, which consists of employing Direct Torque Control (DTC) and Backstepping algorithm. So, a control scheme for the back-to-back converter is provided. Under speed variation of wind, the regulators for grid side and PMSG side converters work simultaneously. The inverter is controlled to preserve a stable dc link voltage, but the rectifiers are controlled to guarantees Maximum Power Point Tracking (MPPT) in a wind system. Also, with Lyapunov analysis, the controller stability is assured. The simulation results show that the presented control approaches are accurate under the platform Matlab/Simulink.

Our simulations consists of studying the organic light emitting diode (OLED) formed by Hole Injection Layer (HIL) /Electron Transport Layer (ETL). We have represented the J-L-V characteristic; the distribution of the electric filed across the device, and investigated the effect of the charge carrier injection contact on the performance of the OLED. The simulation results shows that the charge injection depends strongly on the height barrier contact, we have an improvement of 91.15% in the charge carrier was achieved from a height barrier $leq$0.2eV, and therefore decrease the turn-on voltage by 70%, and the reduction in the height barrier contact results an increase in the formation of the Langevin recombination rate the emission of photon.

Attaining water sustainability is crucial, while the failure to address challenges of the current desalination processes, i.e. high energy demand and cost negatively affects the global development goals. Freeze desalination (FD) technology has a great potential to overcome such challenges as it needs only 20% of energy required by the conventional thermal processes. FD is a crystallization-based technology where freshwater is separated from the saline water mixture in forms of ice crystals by cooling. In this work, high-fidelity numerical simulation of indirect FD process in a rectangular crystallizer is done using computational fluid dynamics (CFD) modeling of incompressible multispecies flow with solidification/melting. The model was used to perform parametric studies considering the effect of (i) initial brine salinity, (ii) freezing temperature, and (iii) initial brine temperature. Results showed that brines with lower salinities tends to provide better process performance. Lower freezing temperature will obviously provide larger ice block; however, it is associated with lower removal efficiency of salt. Similarly, decreasing the initial temperature seems to be highly affecting the growth rates and ice purity. Nevertheless, static layer indirect FD seems to be less productive when compared to other dynamic indirect freezing methods as progressive and falling film. Overall, more insight was given into the FD process using the CFD modeling in which it can be used as a prefect supporting tool for further experimental design and development.

The aim of this paper is an implementation of shunt active power filter (SAPF) supplied by PV generator dedicated to power quality improvement, power factor correction and smooth PV energy injection. SAPF is full bridge inverter controlled by direct current control (DCC) algorithm which consists of an outer voltage regulation loop integrating a fractional order integral plus proportional controller (FO-IP) and an inner current control loop. The PV generator is composed of an emulator with multilevel irradiations, boost converter and P&O algorithm to ensure maximum power tracking. The validity of the global control system has been performed using real-time bench built around a real-time dSPACE card. The results obtained confirm the high performance in steady and transient states of the proposed controller.

In this paper technical and economic feasibility study of hybrid system with storage for a fishing village in the southern Moroccan coastline is carried out. The village under study can stand for most fishing villages of the area of southern Moroccan coastline. Since these villages might not have easy access to the national electricity grid, their energy needs are ensured by highly polluting generators with high energy generation cost in the long term. One of the solutions for decreasing power systems energy cost in these villages is installation of hybrid energy systems. In order to comprehend the viability of such systems, a pilot site was chosen: Lamhiriz, a small village of 4625 inhabitants with an annual consumption of 1.3 GWh. The new power system investigated for Lamhiriz village is diesel-wind hybrid system with electrochemical and thermal storages. First, energy consumption and wind potential of Lamhiriz are presented, then it comes the design of the hybrid system that was approached in two ways: a first configuration of the hybrid system is obtained by economical simulation on HOMER software. In a second step, the sizing problem is solved as an optimization problem where we try to minimize the cost of energy generated by each element of the system in order to meet the electrical demand. Once the optimum sizing obtained, the appropriate energy management is chosen. The GAMS software was used to approach the optimal sizing and energy management. The results found by both HOMER and GAMS are compared in order to see the one meeting the expectations of an optimized system. Energy cost results brought by the optimized hybrid system is compared with energy cost brought by a conventional diesel system.
