In order to increase the production of photovoltaic-based cleaner energy, the maximum power point tracking (MPPT) controller was employed. Because different MPPT algorithms have been adduced in the literature, it is mandatory to compare and differentiate them to select the most adequate MPPT for a particular application or to make suggestions for f...
Floating photovoltaic systems (FPVSs) are a modern concept for clean energy generation, which combine the existing PV systems with a floating structure. Such a combination enables achieving a higher efficiency of PV modules and a best management of land resources which ensures meeting energy requirements more effectively. In this paper, an experime...
One of the major challenges in photovoltaic (PV) systems is extracting the maximum power from the PV array, especially when they operate under partial shading conditions (PSCs). To address this challenge, this paper introduces a novel hybrid maximum power point tracking (MPPT) method based on grey wolf optimization and particle swarm optimization (...
Photovoltaic (PV) systems are gaining more and more visibility as the world power demand is increasing. Unconditional power source availability, ease of implementation, and environmental friendliness of these systems are their major advantages. Nonetheless, the high initial cost and low conversion efficiency of solar PV panels, as well as the inten...

The use of a maximum power point (MPP) tracking (MPPT) controller is required for photovoltaic (PV) systems to extract maximum power from PV panels. However, under partial shading conditions, the PV cells/panels do not receive uniform insolation due to several power maxima appear on the PV array's P–V characteristic, a global MPP (GMPP) and two or...

Due to its several powerful characteristics, the Grey Wolf Optimization (GWO) algorithm has recently become widely used in numerous optimization problems. In photovoltaic (PV) systems, power-voltage (P–V) curves present multiple maxima in case of partial shadow or modules mismatch which can be viewed as an optimization problem. In this paper, a GWO...

The purpose of this study is to investigate the impact of different partial shading scenarios on a PV array’s characteristics in order to develop a simple and easy-to-implement GMPP controller that tracks the PV array’s global maximum power point (GMPP). The P-V characteristic of the PV array becomes more complicated under partial shading, owing to...
Un dispositif constitué d'un bracelet désinfectant pour les mains de son porteur ainsi que les objets qu'il envisage de toucher. Ce bracelet peut être alimenté automatiquement par le mouvement de la main de l'utilisateur ou par des cellules solaires ou dans le cas échéant avec une prise de courant. Il permet de désinfecter la surface des mains et l...
Under partial shading conditions (PSCs), the P-V characteristic of a photovoltaic (PV) array becomes more complicated due to the presence of more than one power peak in contrast to normal conditions (without shading) where there is only one peak named Maximum Power Point (MPP). In this paper, an improved scanning method to track the Global Maximum...
Internet of Things (IoT) technologies, along with economies of scale and advances in hardware, software, and network technologies, have accelerated the explosion of connected objects across the Internet. A connected object can be controlled online from an IoT platform and can send, receive, and process various and varied data. In this chapter, we l...

Photovoltaic (PV) systems based on multi-string configuration are the best effective solution, given its advantages in terms of system availability, reliability and energy efficiency. In this particular configuration each sub-string has its own DC-DC converter and a dedicated maximum power search algorithm which increase the cost and complexity. In...

The partial shading (PS) of the photovoltaic (PV) array is a major problem for the PV systems. Therefore, it is necessary to extract the global maximum power point (GMPP) under partial shading. In this paper, we propose a simple method to find the GMPP. This method scans the P–V curve and memorizes all the peaks in order to get the global peak. Nex...

Do you know or have any image database of solar panels (or plant) containing defective ones (burned,...) and good working ones?
I want to apply a privacy-preserving algorithm in MQTT for IoT devices. Which tool do you suggest to simulate this algorithm? I want to measure the performance on the IoT battery device? Actually, I found many ways such as Matlab, Netsim, MIMIC MQTT, python, and Contiki cooja, but I'm not sure which simulation software is best suited for this? Could you give me a suggestion about the best environment?
