In this research, we study the comparison of the removal of a domestic insecticide declared as an organic pollutant from the water on the surface of the natural clay (N-C) and Montmorillonite sodium (Mnt-Na), where we reveal general information about adsorbents on organic pollutants, as well as physical and chemical methods for their spectral analyses. In addition, we have a simplified explanation of the adsorption phenomenon and then we study the various factors that affect it, represented by the effect of the initial concentration of the pollutant solution, the effect of the pH, temperature and the contact time, conductivity effect, turbidity analysis, and dissolved oxygen analysis. And we have achieved the results that benefit us by comparing the effectiveness of Natural clay (N-C) and Montmorillonite sodium ( Mnt-Na) in the elimination of insecticide, in addition to judging the possibility of describing adsorption by the best adsorbent.

: In this paper, a three-phase shunt active power filter (SAPF) controller with a fully digital implementation is presented. The main goal of this contribution is to implement a digital direct power control (DDPC) algorithm without phase-locked-loop (PLL) for SAPF. This algorithm is intended for power quality improvement and current harmonic elimination. The controller introduced in this paper is costeffective, has a fast-dynamic response, and has a simple hardware implementation. In order to comply with the above specifications, a dedicated controller has been conceived and fully implemented within a field-programmable gate array (FPGA) device. This FPGA-based controller integrates the whole signal-processing functions needed to drive the SAPF, as well as an original method for sector identification. The intended controller provides the desired power references to select the optimal switching sequences. The switching orders follow the grid reference to drive the voltage source inverter (VSI), so the SAPF achieves good performances while ensuring balanced overall supply currents, unity power factor, and reduced harmonic load currents. The proposed digital implementation achieves a valuable compromise between fast dynamic response, minimum execution time, and reduced FPGA resources, through a simple hardware design implementation. The entire system is developed and simulated using VHDL and VHDLAMS languages.

No microscopic analysis is possible without dyes, stains or indicators. Indeed, dyes and stains are extraordinarily critical in biology, biochemistry, molecular biology and microbiological research, because they are frequently used to dye or dye certain cellular components, proteins or DNA/RNA to visualize them. In biochemistry and molecular biology, dyes and stains are used to highlight biological tissues and to quantify or qualify the presence of certain chemicals when attached to substrates. In microbiology, dyes and stains are used to make microorganisms visible or differentiate them due to distinct colorings properties. On the other hand, indicators are often used to measure the pH of the samples. They are added to microbiological culture media to detect the metabolic properties of microorganisms. Despite what has just been said, half a dozen of these dyes (E102, E104, and E129), combined with various preservatives, and are thought to be responsible for hyperactivity in some children. Synthetic dyes are also suspected of causing respiratory problems and allergies. Adsorption remains the most recommended classic technique because of its simplicity, efficiency, ease of implementation and low cost. In this context, our study focused on the removal of three dyes: carmine, phenolphthalein, and eosin b on the surface of two adsorbents: activated carbon, natural clay. We used various physico-chemical techniques to determine the crystalline structure of the DRX device, for this to make a clear idea of the chemical binding by the FTIR analysis and finally to know the maximum absorbance λmax of the dyes it is by the UV-Visible analysis method. In addition, we describe a simplified explanation of adsorption kinetics. The results obtained help us to compare the efficiency of active carbon and natural clay for color removal, in addition to the possibility of describing adsorption by the two models of adsorption isotherms Freundlich and Langmuir.

The phenomenon of mismatch between the modules constituting a photovoltaic (PV) array is one of the problems that frequently occur in PV systems, in particular, the shading issue, which may result in less energy production. To deal with this issue, various configuration methods have been adopted in the literature. However, these configuration methods are suffering from implementation complexity in practice, such as more wiring, more sensors, the need to have more processing, and more memory use. In the present paper, a comparative study between the current balancing (CB) and particle swarm optimization (PSO)-based PV reconfiguration methods is carried out using MATLAB/Simulink software. The reached findings under varying partial shading conditions (PSCs) are investigated to determine the best approach among them.

To ensure the safe and stable operation of solar photovoltaic system-based power systems, it is essential to predict the PV module output performance under varying operating conditions. In this paper, the interest is to develop an accurate model of a PV module in order to predict its electrical characteristics. For this purpose, an artificial neural network (ANN) based on the backpropagation algorithm is proposed for the performance prediction of a photovoltaic module. In this modeling approach, the temperature and illumination are taken as inputs and the current of the mathematical model as output for the learning of the ANN-PV-Panel. Simulation results showing the performance of the ANN model in obtaining the electrical properties of the chosen PV panel, including I–V curves and P–V curves, in comparison with the mathematical model performance are presented and discussed. The given results show that the error of the maximum power is very small while the current error is about 10-8, which means that the obtained model is able to predict accurately the outputs of the PV panel.

This paper proposes a generalized technique to minimize power losses of PV arrays connected in Total Cross-Tied (TCT), under both current and voltage mismatch effects. The proposed method is based on the classification of the electrical data of the PV modules composing the photovoltaic array in order to identify the mismatch type, then applying an arrangement of the PV modules according to the mismatch type found. The design process of the proposed algorithm is detailed and its validity and performance are verified under different mismatch scenarios. The efficiency enhancement is verified for different mismaths cases and the computed results reveal that the proposed algorithm can achieve an improvement of around 30% in the PV array power. Furthermore, a comparative study with SuDoKu and genetic algorithms are performed. The obtained results under MATLAB/Simulink software highlighted the superiority of the proposed method in comparison to the compared ones. The enhancement resides in the implementation simplicity as well as in the minimization of the number of infection points indicating smooth I-V and P-V characteristic curves.

This paper presents a novel circuit-based model of photovoltaic (PV) source (cell, module or array) that can be easily integrated into any circuit-oriented simulators such as PSpice, PSCAD/EMTDC, PSIM, PowerSys of MATLAB/Simulink, etc. This proposed model is able to simulate accurately any commercial PV module behavior either exposed to uniform or non-uniform irradiance distributions. Moreover, it can also simulate perfectly PV arrays behavior in large scale PV systems. It is mainly derived from the conventional one-diode equivalent circuit model, which consists of a current source, a diode and two resistors. By modifying the linear part of this latter and including implicitly the effect of weather parameters (irradiance and cell temperature) on the circuit elements, our proposed model will encompass two types of dependent sources (voltage and current sources) and two resistances. To validate the truthfulness of the proposed novel model, comparisons between simulated and outdoor measured I-V characteristics on commercial PV module are done. Preliminary results have shown promising outputs and accuracy of this model.

This paper is intended to contribute to the conceptual design of an electronic helping tool to analyze the performance of maximum power point tracking systems(MPPT). Indeed, the MPPT is a device ensuring the connection between the PV generator and the rest of the PV conversion chain in order to extract and transfer the maximum of the electric power. In this work, we present a new method in analyzing MPPT performance witch the principle is based on the comparison of the maximum power(Pmp) that can be generated by the PVG and the power transferred to the DC load by the MPPT system. The measurement of these powers is realized outdoor with an online mode; i.e., the PV conversion chain is maintained in operation. The Pmp value obtained by measuring the couple (Isc, Voc). In this paper we will present the hardware implementation of the proposed technique. The measurement of climatic parameters such as, solar radiation and cell temperature are not taken into account, which characterizes the peculiarity of this method. Keywords: PVG, Maximum power, MPPT, Online measurement, Analysis.

Partial shading of a photovoltaic array is the condition under which different modules in the array experience different irradiance levels due to shading. This difference causes mismatch between the modules, leading to undesirable effects such as reduction in generating power and hot spots. The severity of these effects can be reduced by changing module interconnections of a solar array, three different interconnections configurations, series-parallel (SP), bridge-linked (BL) and total-cross-tied (TCT) of photovoltaic generator are studied using simulation models to compare their performances, also studied their characteristic parameter variation in the function of shading, with a special attention to: Open circuit voltage (Voc), Short circuit (Isc), Maximum power (Pmp) and fill factor (FF) evaluation, in order to find which configuration is less influential to partial shading effect.

Abstract—In fact that the meaningful parameters of photovoltaic (PV) module model are of major importance, they could lead to carry out a monitoring tool, so the extraction method should be accurate and quick in the same time. Due to the nonlinear and implicit nature of the circuit equivalent PV module model it is preferable to use a good optimization method; in this paper we opt for a metaheuristic based parameter identification method inspired from Artificial Bee Colony (ABC) and Differential Evolutionary (DE). The proposed method is compared with other optimization methods and then is validated with a real measured data under different meteorological conditions of several PV modules.

Recent advances in control algorithms embedded into a Field Programmable Gate Array (FPGA) allowed the application of such algorithms in real engineering problems (robotic, image and signal processing, control, power electronics, etc.), however, the application of such technologies in the solar energy field is very limited. The embedded advanced algorithm into FPGA can play a very important role in renewable energy systems for control, monitoring, supervision, etc. FPGA technology was employed due to its development, flexibility and low cost. In this paper, the incremental conductance (IncCond) algorithm is implemented on FPGA for tracking the Maximum Power Point (MPP) of a photovoltaic (PV) array. The IncCond algorithm has been designed using a description language (VHSIC standing for very-high-speed integrated circuits) then implemented on Xilinx Virtex-II-Pro(xc2v1000-4fg456. Modelsim-based simulation results confirm the good tracking efficiency (96%) and rapid response time (2ms). It has been confirmed that the implemented algorithm performs better than the well known Perturb and Observe (P&O) algorithm.
