All interventions that enhance livelihoods of poor rural families in remote areas of the Maghreb will positively impact standard living, involve technological solutions, and likely enhance agricultural production, which in turn can further contribute to poverty reduction. Hybrid green energy systems (HGESs) have been more exploited to supply a mobile base transceiver station (BTS) by clean electricity, or assess the energy availability in smart grids (SGs) of such areas. In this paper, a HGES has been modeled to produce energy from PV/Wind HGES in grid-connected BTS or SG sites, using MATLAB to solve a theoretical model, and simulated with a suitable configuration for performance analysis and optimal sizing. A techno-economic simulation, carried out using the HOMER package, has evaluated such HGES feeding BTS or SG in a remote area-prototype (RAP) of the Maghreb, and optimized the size and assess hybrid PV-Wind system based on weather conditions for RAP. The results may impact rural livelihood and improve standard living of people in such countries.

In this chapter, a proposed indirect field oriented control (IFOC) based induction motor drive for solar PV water pumping system (SPVWPS) powered by the two-level inverter is presented. The proposed scheme aimed at enhancing the performance and the dynamic response of the PV system. It consists of operating the induction motor at optimal reference flux which leads to improve the overall efficiency of the SPVWPS. The proposed IFOC scheme will be investigated experimental implementation using the dSpace DS1005 board. The proposed SPVWPS is evaluated and compared with the conventional IFOC under reel climatic conditions. Experimental results illustrate the effectiveness of the suggested control strategy in terms of pumped water, minimization of absorbed current, and overall efficiency.

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 leverage some of the IoT technologies to propose a simple and low-cost IoT solution to monitor and control a smart dual-axis solar tracker system for performance evaluation. The solution also includes alert notifications to inform a remote user through phone or mail (or both) when a sensor has reached a certain predefined event. The solution is designed based on low-cost and easy-to-use hardware and software and an online open-source IoT platform. The design aspects of the IoT-based solar tracker are extensively described in this chapter. Moreover, a prototype of the IoT-based solar tracker has been manufactured and tested. Test results demonstrate that solar tracker data can be sent easily and properly and can be directly monitored online, as well as the solar tracker, can take commands from the IoT monitoring application.

In off-grid photovoltaic (PV) systems, a battery charge controller is required for energy storage. However, due to unstable weather conditions as well as the frequent variations in load demand, the PV power flow delivered to the load could be fluctuated while the battery charging efficiency will be reduced. To overcome these issues, this paper presents an improved power balance control strategy based on two proportional and integral (PI) compensators only, which can adequately balance the PV power flow delivered to the DC load and the battery, so that the PV power is effectively utilized and the battery is properly charged. First, a modeling of the entire system based on the linear PV array model is performed to simplify the design of the PI compensators. In addition, four operating modes are adapted to deal with the aforementioned issues regarding any variation in weather conditions and load demand. Namely, Maximum Power Point Tracking (MPPT)-mode, Non-MPPT mode, Night-mode, and Off-mode. Afterwards, a digital anti-windup control strategy associated with PI compensators is also developed to ensure a smooth switching from an operating mode to another. Moreover, an improved Incremental Conductance IC-MPPT algorithm is adopted to extract the maximum power from the PV array. Finally, MATLAB/SIMULINK simulations are carried out and the results obtained demonstrate the good performance of the proposed control strategy under different atmospheric conditions, both in power balance control and MPPT control, notably in terms of efficiency (99.79%), steady-state power oscillations (0.03 W), and convergence time (0.03 s).

Nowadays, electrical grids are using information and communication technologies for providing intelligence in electrical grids, since alternative energy sources are increasing to meet the world’s energy consumption demand. Interest in Internet of Things (IoT) is lastingly growing and may involve more data-sensitive projects when applied in smart micro-grids (SMGs), and security is a priority to be ensured for power distribution and consumption. Moreover, standards for IoT platforms should be optimized for monitoring such consumption and controlling grid resources, which present more demanding challenges. In such context, this work aims to adopt an appropriate PV-based energy generation system feeding a remote telecom network (RTN), via evaluating its performance, and monitor a related smart micro-grid (SMG) to offer a secure and energy-efficient management for RTNs. Simulink simulations have proved DC/DC converters as the best choice for future telecoms applications by using PV systems. Boost converters reveal to be suitable for PV systems while optimizing a fewer transformers electric energy conversion. A focus is also on how to detect and counteract attacks to prevent power theft/loss while feeding RTNs, showing that the best security choice is the use of Snort to prevent from inside net LAN, and ASA firewall to obstruct attacks from outside.

With the development of wind power generation in recent years, several studies have dealt with the active and reactive power control of wind power systems, along with the quality of energy produced and the connection to distribution networks. In this context, this research proposes a new contribution to the field. The major objective of this work is the development of a nonlinear adaptive backstepping control technique applied to a DFIG based wind system and an optimization technique that uses the rooted tree optimization (RTO) algorithm. The backstepping control strategy is based on the Lyapunov nonlinear technique to guarantee the stability of the system. It is applied to the two converters (i.e., machine and network sides) and subsequently improved with estimators to make the proposed system robust to parametric variation. The RTO technique is based on monitoring the behavior of the underlying foundation of trees in search of underground water in accordance with the level of underground control. The solution proposed for the control is validated using two methods: (1) a simulation on MATLAB/Simulink to test the continuation of the reference (real wind speed) and the robustness of the system and (2) a real-time implementation on a dSPACE-DS1104 board connected to an experimental bench in a laboratory. Simulation and experimental results highlight the validation of the proposed model with better performance compared with other control techniques, such as sliding mode control, direct power control, and field-oriented control.

The world is facing a new challenge to overcome the pandemic disease of Coronavirus (COVID-19). An outbreak of COVID-19 to more than 213 countries and territories caused damage to the economy of every country. The proper vaccine to combat this pandemic disease is not invented yet. Due to the lockdown situation, there is a shortage of daily used products globally. To overcome the issue of food shortage and economic survival, the world has to ease the lockdown rules and become operational with the precautionary measures. COVID-19 has a fast transmission rate, therefore, while living with COVID-19, breaking the fast transmission chain of COVID-19 is the only vital solution. Furthermore, there is a dire need to disinfect every individual and his luggage at the entrance of every shopping mall, hospital, public and private institutions, bus stops, metro stations, and railway stations. Hence, the proposed walk-through gate (WTG) with different sensors, i.e., infrared thermal camera, UV disinfectant sensor, disinfectant spraying system, touch-less hand sanitizer, and box having a face mask with a dustbin to discard the previous mask can provide an effective and efficient relief. The world cannot stop working and cannot survive for more than 3–6 months in a lockdown, hence the proposed idea is to install the disinfectant automated spraying WTG with a security walk-through gate at every possible entrance to conform living with the COVID-19 disease such as many other diseases. Breaking the transmission chain is the only solution to win the battle against COVID-19 until an effective vaccine invention.

This work develops a real-time implementation on the DSPACE environment of an adaptive non-linear control strategy for a wind energy conversion system (WECS) based on the doubly-fed induction generator (DFIG). The DSPACE-DS1104 board is directly associated with an experimental bench of a wind power system. The non-linear backstepping controller has been realised to control the active and reactive powers of the DFIG connected directly to the electricity grid via two converters (grid side and machine side). First, a full review of the WECS is discussed. Subsequently, a detailed description of the backstepping control laws based on the Lyapunov stability technique is reported. Consequently, a simulation on the Matlab & Simulink environment was carried out to test the proposed control model in terms of performance and robustness. The second part of this work was devoted to the experimental validation of the adaptive backstepping control algorithm on a test bench to prove its efficiency. The results obtained show a perfect correlation between simulations and experiments (in static and dynamic regime) even for fluctuating wind speed.

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 experimental investigation of a small-scale FPVS is presented. It is designed and built for research and demonstration purposes as a first attempt to analyze this concept under Moroccan operating conditions. The objective is to analyze and compare the electrical and thermal performances of an FPVS with those of an overland PV system (OPVS) with a similar nominal capacity. To do this, a test bench consisting of FPVS and OPVS and measurement station has been proposed and established. The design and construction aspects of the FPVS, as well as the experimental setup of the entire test bench, are extensively described in this paper. The test results show that the average temperature of the FPV modules, during the test period, was always lower compared to that of the OPV modules with a difference of up to 2.74 °C. This means that FPVS can benefit from the natural cooling effect of water and operate with higher efficiency as compared to OPVS. It was also found that the FPVS generates up to 2.33% more daily energy than the OPVS. Further, an experimental test was also performed in this work to compare the energy production of FPVS under different tilt angles. The test result confirms that the FPVS produces the highest energy when it is installed at the annual optimal tilt angle. Hence, adjusting the PV modules at their optimal tilt angle is recommended as well for FPVSs.

This work is aimed at achieving a simple and reduced-cost configuration of photovoltaic (PV) water pumping system (PVWPS) using an induction motor with high efficiency. The proposed PV system is composed of two stages of converters which the first one ensures the maximum power point by controlling the duty ratio of boost converter using variable step size incremental conductance (VSS INC) technique. Fuzzy logic control based on direct torque control is proposed to serve the purpose of operating an induction motor. Moreover, the combining of these proposed control strategies has been never discussed. The proposed control scheme is modeled and simulated in detail under MATLAB/Simulink software to evaluate its performance under fast variations of irradiance and daily climatic profile. The obtained simulation results using the suggested control strategies are compared to those using the most used method in the literature (variable step size perturb and observe (VSS P&O) algorithm). The simulation results indicate that the proposed PVWPS performed best in terms of the time of response; pumped water, flux ripples, and the stator currents are reduced.

This concept paper describes a device consisting of a disinfectant wristband for the hands of the wearer and objects that the wearer intends to touch. This wristband can be powered automatically by the movement of the user’s hand or by solar cells or, if necessary, by a power outlet. It disinfects the surface of the hands and the objects in front of them using an ultraviolet (UV) lamp. Control and monitoring can be carried out automatically or manually, which guarantees complete and effective disinfection. The electronic control system, which is fully integrated into the UV emitter head, regulates the intensity and duration of the UV radiation and also manages the electrical energy. In addition, the wristband can be fitted with an optional watch to improve its decoration and ergonomics. The device in question has a compact, elegant, and practical shape. This hand sanitizing wristband can be an effective tool in the fight against the current COVID-19 pandemic and, in general, help to address the health challenges related to hygiene and disease prevention.

Photovoltaic (PV) systems based on multistring configuration are the best effective solution, given its advantages in terms of system availability, reliability, and energy efficiency. In this particular configuration each substring has its own dc–dc converter and a dedicated maximum power search algorithm which increase the cost and complexity. In this article, an efficient centralized global maximum power tracking (GMPPT) algorithm for multistring PV array subject to partial shading conditions is proposed. The algorithm is based on artificial bee colony (ABC) as an optimization approach to provide the optimal duty cycles allowing the extraction of the optimal global maximum power from each substring. In particular, the proposed approach allows significant reduction of the required sensors to only one pair of current and voltage sensors, at the common point of connection of the overall PV strings. The simulation study has been carried out under Cadence/Pspice and MATLAB/Simulink platforms on the I–V curves to confirm the effectiveness of the proposed algorithm when several shading patterns occur. In addition, complex shading pattern of a daily profile has been also carried out to demonstrate the GMPPT finding in dynamically variable conditions. Performance comparison against particle swarm optimization based maximum power point tracking algorithm and the traditional perturb and observe method has also been carried out. The obtained simulation and experimental results have shown the effectiveness and a good tracking capability of the proposed ABC algorithm in a multistring PV array configuration under uniform and nonuniform irradiance.

Power limitation and load reduction are considered the main challenges for the large scale wind turbine when the system operates in the above rated wind speeds. The controller design still a complex and critical task in the presence of the system nonlinearities and the wind turbulent behavior to produce a cleaner energy without switching harmonics. In this context, an adaptive controller based on fuzzy logic concept is proposed to limit the extracted power at rated value with improving its quality and to mitigate the loads applied on the turbine and the drive train in full loads conditions by adjusting the pitch angle. First, the different parts of the DFIG wind system are modeled. Thereafter, the main control structures in different operating regions are briefly described. The second part is focused on the pitch control technique. The initial parameters of fuzzy logic controller (FLC) are defined based on literature studies. Then, those parameters are tuned to derive the optimized FLC. Finally, the scaling factors of this last configuration are automatically adjusted by means of a correction factor to develop the Adaptive FLC. By the end, a technical and economic comparative studies are conducted between the three fuzzy controller configurations and the classical structures which are classical PI controller and Gain scheduled PI controller using several performance indicators. The responses assessment obtained from virtual simulation using MATLAB/SIMULINK show that the adaptive FLC is the best solution for the pitch control in terms of rapidity, stability and robustness and allow producing higher electrical energy with lowest harmonics rate.

The real implementation of the maximum power point tracking (MPPT) controllers for the photovoltaic (PV) systems is still a big challenge for researchers working in this field. Often, they use simulation tools to assess the performance of their MPPT algorithms before actual implementation. In this context, this paper aims to propose a trusted simulation of a PV system designed under Proteus software. The proposed PV simulator can be used to verify and evaluate the performance of MPPT algorithms with a closer approximation to the real implementation. The main advantage of this model that it contains a real microcontroller, as can be found in reality, so that same code for the MPPT algorithm used in the simulation will be used in real implementation. In contrast, when using (Powersim Software) PSIM or Matlab/Simulink, the code of the algorithm must be rewritten once the real experiment begins, because these tools don’t provide a microcontroller or an electronic board in which our algorithm can be implemented and tested in the same way as the real experiment. After this section, a modified Hill-Climbing (HC) algorithm is introduced. The proposed algorithm can avoid the drift problem posed by conventional HC under a fast variation in insolation. The simulation results show that this method presents good performance in terms of efficiency (99.21%) and response time (10 ms), which improved by 1.2% and 70 ms respectively compared to the conventional HC algorithm.

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. Next, we control a boost DC–DC converter to extract the GMPP from the PV system. In addition, this Method allows following the dynamic GP under variant SPs with less oscillations around the stable state compared to the existing works.

This paper aims to improve the induction motor (IM) performance for photovoltaic (PV) water pumping systems (PVWPS) without battery storage. The proposed technique is designed by direct torque control based on fuzzy logic controller (FLC). The purpose is to ensure optimal control of flux reference to reduce motor losses and hence, the efficiency of the PVWPS is improved. The maximum power point tracking (MPPT) is achieved using a variable step size Perturb and Observe (VSS P&O) algorithm. The PV system incorporating the proposed technique is tested and compared with the control scheme based on constant flux reference under a real annual data of atmospheric conditions of the target site. The simulation results indicate the effectiveness of the proposed control strategy in terms of the reduction in stator current, optimizing flux, electrical speed and pumped water.

This work presents a design of a system-on-chip for the telemetry of photovoltaic curves of a nanosatellite in real time, based on the work reported by Gutiérrez et al. [1]. In this type of application, the limitation of memory and communication bandwidth makes it difficult to store and transmit the whole I-V characteristic curve of any solar section in real time. The proposed solution is based on the real-time calculation of the equivalent single diode model of the solar section. Thus, once the parameters calculated, recorded and transmitted, regardless of the operating conditions, the specific curve could be reproduced later. The system is based on a 32-bit LEON3 microprocessor core implemented in a FPGA. LEON microprocessors were originally designed by the European Space Agency for use in space projects requiring high reliability. Moreover, in order to design the system as simple and reliable as possible, among all the methods available in the literature to extract the five parameters of the equivalent model (Iph, Is, n, Rs and Rsh), the method Asymptote Oblique (OA) [2] was chosen for its simplicity and precision. These parameters (Iph, Is, n, Rs, Rsh) are recorded and transmitted to the ground for later reproduction using the following equation: I= I p h − I s ( e V + I R s n V T − 1 ) − V + I R s R s h ( 1 ) In summary, the final system consists of three blocks: 1) LEON3 microprocessor, as shown in Figure 1, which executes the OA method to obtain PV characteristic values from the detected values. 2) Electronic load, as shown in Figure 2 to set the PV output voltage to a value defined by SoC LEON3. 3) Acquisition interface, as shown in Figure 3 which allows to obtain the value of the voltage and the current of a pilot cell and to adapt them to values that can be acquired by the digital system.

This paper presents an implementation of real-time energy management systems (EMS) to maximize the efficiency of the electricity distribution in an isolated hybrid microgrid system (HMGS) containing photovoltaic modules, wind turbine, battery energy storage system, and diesel generator (DG) which is used as a backup source. These systems are making progress worldwide thanks to their respect for the environment. However, hybridization of several sources requires power flow control (PFC). For this reason, in this work, a proper energy management system is developed using LabVIEW software and embedded in a suitable platform for the real-time management of the hybrid energy system. The developed EMS is tested and validated through a small-scale application which accurately represents the case study of an isolated mosque located in a remote area of Morocco. The aim of this paper is to (i) propose a novel modelling method and real-time monitoring interface under the LabVIEW software based on the real data obtained by an optimal sizing previously made using Homer-pro software and (ii) implement the power control system on a low-consumption embedded platform that is the Raspberry-pi3.
