Pumping water using multiple energy sources is the ideal solution for supplying potable water in isolated or arid areas where there is no supply of grid power. In this paper, an effective control, and energy management strategy for a stand-alone photovoltaic-batteries water pumping system for agriculture applications is presented. The system is composed of solar photovoltaic panels as a primary energy source, and Lead-Acid batteries as a seconder energy source to supply the BLDC motor that drives the centrifugal pump. The energy management strategy uses an intelligent algorithm to satisfy the energy demanded by the motor, also to maintain the state-of-charge of the battery between safe margins in order to eliminate the full discharge and the destruction of the batteries. Drift is a major problem in photovoltaic systems;this phenomenon occurs when solar irradiation changes rapidly. Classical power maximization algorithms do not solve this problem, for this reason, a Modified Perturb & Observe (MP&O) has been implemented. The obtained results show a fast convergence performance to the maximum power point compared to the conventional Perturb & Observe (P&O). Computer simulation results confirm the effectiveness of the proposed energy management algorithm under random meteorological conditions. © Springer Nature Singapore Pte Ltd. 2021.

In this paper, a photovoltaic (PV) system, with maximum power point tracking (MPPT) connected to a differential inverter is presented. The main characteristic of the used inverter is its potential ability to adapt to the permanent variation of the incident solar irradiation intensity that consequently imposes variable electrical quantities at the output of the PV panels, whereas our devices function with fixed electrical quantities. This set of related algorithms will identify the suitable duty ratio in which the DC/DC converter should be operated to maximize the power output, and suitable duty ratio in which the DC/DC/AC converter works according to the reference output signal. Results showed that this inverter is able to reach the output voltage reference despite the input voltage variation. © Springer Nature Singapore Pte Ltd. 2021.

Compared to other transportation technologies, fuel cell hybrid electric vehicles have been widely considered as one of the most promising alternatives for transport applications, due to their zero-emission, low noise, and high efficiency. This paper presents an energy management strategy for a hybrid electric vehicle powered by a fuel cell as the main source and Li-Ion battery as a secondary source. Our proposed approach is based on fuzzy logic and aims to decrease hydrogen consumption while increasing the durability of power sources by respecting their dynamic constraints as well as the battery's state of charge. The fuzzy logic controller takes as inputs the load power and the battery state of charge and outputs the fuel cell power. The simulation model of the hybrid electric vehicle and its energy management strategy are established using MATLAB/Simulink. The simulation results show the correct functioning of our model and demonstrate that the proposed control strategy shows a good performance in improving fuel economy and the effective distribution of energy between sources.

This paper presents the modeling, control and optimization of a photovoltaic water pumping system. The system consists of a DC-DC Boost converter, which is used as a link between a Solar Photovoltaic (SPV) panels and the three-phase inverter (VSI) to feed the BLDC motor. A centrifugal pump is connected to this motor in order to use the water pumped afterwards to multiple applications. Maximum Power Point Tracking (MPPT) control techniques are an essential part of improving the efficiency of photovoltaic (PV) systems. It is principally used to extract maximum possible power of the PV modules under any condition of solar irradiation. For this reason, PO algorithm is used due to its high performance and its simplicity of implementation. The DC-DC Boost converter, compared to the various common DC-DC converters (Buck, Buck-Boost, SEPIC, Cuk..) has many benefits in SPV based applications, such as limiting the starting current of the motors. Using a BLDC motor is found to be the best option because of its high efficiency and reliability, better performance, and requires low maintenance. The considered system as well as the control strategies has been implemented in MATLAB-Simulink environment. The results show the effectiveness of the studied photovoltaic water pumping system. © 2019 IEEE.

Compared to the conventional ISFET device, the silicon nanowire ion-sensitive field-effect transistors sensors (Si-nw-ISFET) has attracted a lot of attention and is considered as one of the most promising candidates because of their biocompatibility, very high surface-to-volume ratio due to the very small sizes of the nanowires, fast response, and good reliability of the signal. This paper deals with the modeling and performance evaluation of Si-nw-ISFET (Silicon-nanowire chemical field effect transistor) microsensor. The modeling approach used in this work takes into account the nanowire size effects to evaluate the response of Si-nw-ISFET transistor and introduces two parameters: the total resistance of nanowire R T and the rectangular capacity C ox of the gate insulator all-around the Si-nw. This model investigates the main influential parameters of nanowire on the sensor response as: (i) different wire lengths Lnw, (ii) channel gate lengths of Si-nw-ISFET (i.e. short and large gate length) and (iii) different numbers of parallel wires. The model developed is tested on large pH range, evidencing a good fit between simulation and experimental results. The model studied can predict the Si-nw-ISFET response behavior and creates new opportunities for new innovative applications.

Dust deposition on the front of photovoltaic /thermal collectors presents greatest issues in some regions (desertic regions). It's considered as key parameter affecting much more collector's performances. In the present work, a particular attention has been paid to dust deposition effect on the electrical and thermal performances of photovoltaic /thermal collector PV/T.A model of sheet-and-tubes PV/ T collector is developed and validated with experimental data available in literature. The obtained results show that the dust significantly affects the electrical and thermal efficiencies. An increase of dust deposition of 8g/m2 causes an electrical and a thermal output reduction respectively of 28% and 21%. Better electrical and thermal performances have been noted for PV/ T without dust. Moreover, a good agreement has been observed between obtained results and the presented results available in literature.

Compared to conventional PV/T solar collector, the bi-fluid PV/ T type enables to extract more heat producing hot air and hot water and thus increasing the total efficiency per unit of area. The use of both fluids leads to provide a variety of PV/ T thermal applications. In this paper, a mathematical modeling of a bi-fluid photovoltaic/thermal PV/ T solar collector type is developed and simulation was performed using MATLAB software. Furthermore, a performances comparison is carried out for four bi-fluid PV/ T collectors using different cooling fluid (***,water) in simultaneous operating mode. In this context, the temperature distribution in different collectors layers, electric power generation efficiency and thermal power efficiency are evaluated and analyzed. According to obtained results, water- water cooled PV/ T collector proves a good effectiveness and reaches a higher electrical and thermal efficiency respectively of 11.16 % and 54.22%. This bi-fluid type is considered as the most provider of hot water in contrary to Air-air cooled PV/ T witch providing more hot air.

When the panels in a photovoltaic generator (PVG) are subjected to Partial Shading (PS), some bypass diodes may turn on, and consequently multiple peaks in the Power -Voltage (P-V) characteristic are produced which reduces the output power. For an optimal GPV power extraction, one of emerging PS mitigation techniques is to reconfigure the PVG by altering the electrical connections between panels according to prevailing conditions. This paper presents a reconfigurable PV architecture based on irradiance equalization row approach for a PVG connected on Total cross tied (TCT) scheme. The proposed technique uses fuzzy logic as an optimization tool to obtain uniform shade dispersion throughout the PVG, either keeping the same number of panels in each row or forming rows with different number of PV panels. To evaluate the effectiveness of proposed fuzzy logic controller (FLC), extensive simulations with different shade patterns are carried out on Matlab/Simulink. Thorough analysis with the help of characteristics curves and the results obtained for the full PV chain conversion are performed. Results of simulation show that the proposed reconfiguration method exhibit superior results as compared to fixed TCT interconnection and enhanced irradiance equalization (IEq) method in terms of efficiency, power loss and response time.
