In the context of reducing carbon emissions, electric vehicles seems to be a good solution, especially when they are charged by a solar powered carport or charging station. This paper presents modernization, control, and energy management of an industrial electric vehicle with a solar energy supply. This scheme is applied to a previously existing electric forklift using Lead Acid battery and a Direct Current motor, which are replaced, by a new Lithium Ion battery and a Permanent Magnet Synchronous motor. The work starts with the sizing of new elements of the electric vehicle and the solar charging rooftop, then the mathematical modeling of all the elements of the whole system is performed. The perturbation and observation technic was used to assure the extraction of maximum power from the solar panels to charge the electric vehicle batteries. The Backstepping control technic was used to control the Permanent Magnet Synchronous motor in order to assure the pursuit of the desired speed. The models and the control technics are implemented and simulated in MATLAB SIMULINK software to evaluate the efficiency and performances of the adopted system.

Failure of overhead power lines usually occurs through conductor creep after several years of service. The best solution to investigate the creep behavior of the conductor in a very short time is to perform a creep test in the laboratory using a creep machine. In this present work, a fabricated horizontal creep testing machine was presented and tested by performing creep testing on electric aluminum wire used for the construction of overhead power lines. The different parts of this machine have been described. The main feature of this machine is the displacement acquisition system and the possibility of performing any test. The creep results obtained in this machine confirmed its good performance. The failure behavior of the aluminium wire was characterized by scanning electron microscopy.

This paper discusses the power quality of the network. It will focus on three parameters: power factor correction, harmonics filtering, and unstable voltage and frequency. Mathematical calculations will be presented in this paper to show the advantages of improving these parameters and the consequences of improper design for it. Moreover, two case studies will be discussed to prove the mathematical calculation and simulate the network before and after improving the power quality parameters. One case study will focus on harmonic filtering in the network. However, other case study will be focused on improving the power factor in the power network. Moreover, the effect of renewable energy such as solar power on the network voltage and frequency and how it can be solved by using battery energy storage system along with renewable energy generation are discussed.

This paper presents a three-phase shunt active power filter connected to a Photovoltaic (PV) source by the means of DC-DC boost converter for total harmonic distortion (THD) reduction, reactive power compensation, and PV power injection. For harmonic current estimation instantaneous reactive power theory is used. A high gain anti-windup PI controller is used to control the voltage across the dc-link. A maximum power controller based on fuzzy logic is used to track the maximum point. The presented system is validated through an extensive simulation carried out using Matlab/Simulink under various operating scenarios.

This article proposes a novel three-port converter with a fault-tolerant (FT) capability to reconFigure automatically under different switching fault conditions, i.e., open circuit fault (OCF) or short circuit fault (SCF) of the power transistors, and to continue achieving different control objectives such as effective battery charging, maximum power point tracking (MPPT) and output voltage regulation. The proposed fault-tolerant design with a one-level redundancy structure enhances the reliability of traditional three port converters (TPCs), but it also addresses the component failure while different modes of operations using fewer components by incorporating dual-input single-inductor structure into the converter design. Simulation results are presented to explain the performance of the proposed converter during different fault conditions and the reconfiguration mechanism during these conditions.

This paper proposes a novel permanent magnet/reluctance composite rotor dual stator low speed synchronous motor (PMRCR-DSLSSM). The rotor of PMRCR-DSLSSM is composed of surface permanent magnet and synchronous reluctance. The motor not only separates the permanent magnet torque and reluctance torque, but also makes full use of the reluctance torque to maximize the output torque of the motor. Therefore, the composite rotor can be designed more flexibly, and it brings great convenience to the control of the motor. The electromagnetic performance of the motor is simulated and analyzed by finite element method (FEM). The results show that the torque ripple of the motor is reasonable, the torque density is improved compared with that of the permanent magnet motor with the same volume, and the motor performance meets the design requirements.

Achieving carbon neutrality is one of the important goals for many developed and developing countries worldwide. One method to reduce carbon emissions and reach carbon neutrality is the extensive utilization of renewable energy sources (RES). Even though there are significant benefits of the high penetration of RESs to the electrical grid, there are some challenges: the losses in the AC transmission lines. With the current improvement of power electronics devices, the DC transmission lines can be more viable technically and economically for various reasons. To name a few, DC transmission lines do not suffer from the skin effect. Also, corona losses are significantly lower in the case of DC systems. However, DC transmission line faults pose a protection challenge due to the lack of zero-crossing points, which erupt high fault magnitudes with a short rise time. Coupled with the fact that existing DC circuit breakers have long operation times of up to 4 msec. In this paper, superconducting fault current limiters (SFCL) are proposed to be used as a protection solution for the DC transmission line of the solar farm. The SFCL can reduce the fault currents and support the protection system during fault scenarios. A community solar farm, DC transmission lines, rectifiers, inverters, and SFCLs have been modeled in MATLAB/Smilunk to carry out the fault analysis in the DC transmission lines and test the performance of the SFCL model during fault scenarios.

Recently, Global Optimization algorithms are becoming an efficient tool to solve complicated problems for various applications. Modern optimization algorithms like Black Hole Optimization (BHO) and Social Spider Optimization (SSO) algorithms are widely used to solve different problems. This paper is demonstrating the applicability of these techniques for training an artificial neural network (ANN) and finding optimal values for the weights and biases. The proposed optimization-based ANN model has been utilized to model the IV characteristics of Gallium Nitride High Electron Mobility Transistor (GaN HEMT). A very good fitting is obtained with measurements which shows the validity of both BHO and SSO for this application.
