Wind Turbines (WT) became essential renewable energy sources as the WT farms contribution reached megawatts scale. However, wind turbine blades (WTB) are subjected to failure due to running in harsh environments such as ultraviolet (UV) radiation, ice, temperature variation, dirt, and salt. Consequently, a periodic inspection process is required. In this paper, the design and implementation of a scaled down prototype magnetic climbing robot is proposed that can be used for WT blade inspection. The robot is equipped with two arms that can be extended one meter long to come close to the blade for inspection. Each arm is equipped with a gripper that can hold an inspection tool of weight up to one kilogram.

The growing popularity of private vehicles’ electrification will have a negative impact on the electric power system, especially on the distribution networks, if electric vehicles (EVs) charging is not managed properly. In this paper, a new technique for smart charging of EVs is proposed and tested with simulation. A fuzzy logic controller is used to control and manage the EV charging process to maximize electric utility and EV owner benefits. The electric utility’s benefit is to mitigate the EV charging impacts on the distribution network by shifting EV charging to the off-peak period, while EV owners’ benefit is to charge the EV at low cost. The controller regulates and controls the EV charging power depending on electricity price signal provided by the electric utility and EV battery state of charge (SoC). This controller needs basic communication with the electric utility to receive the electricity price signal every 1 hour. The objective of the controller is to charge EVs at low cost while keeping the normal operating conditions of the distribution network. MATLAB/SIMULINK is used to perform simulations and test the effectiveness of the proposed smart charging method. The results demonstrated that the proposed smart charging method reduced the impacts of EVs charging on the distribution network compared with uncontrolled charging.

The direct drive permanent magnet synchronous generator (PMSG) have many advantages consequently, it ends up a standout amongst the most appealing variable speed wind generation types. This paper proposes a novel application of a Whale Optimization Algorithm (WOA) aims at finding the optimal parameters of the conventional Proportional-Integral (PI) controllers for the permanent magnet synchronous generator based wind energy conversion system (WECS). The Whale Optimization Algorithm (WOA) is applied to the classical PI-controller on machine side converter system to find the optimal gains of the PMSG, to such an extent that a maximum power point tracking (MPPT) under normal condition, a step change of wind speed and the optimal dynamic performance of PMSG under grid fault can be easily achieved. Three case studies in this paper, dynamic responses of the system under normal operation, a step change of wind and a three-phase symmetrical fault with using crowbar protection and without crowbar protection. The optimal values that result from the WOA algorithm are compared with the simplex method.

This paper proposes augmented Grey wolf optimizer (AGWO) for solving the radial distribution network reconfiguration problem. In the developed algorithm, the optimal switches combination is determined to change the topological structure of the system and reduce the total real power losses subject to the system operating constraints. AGWO inspired from behavior of the alpha α, and beta β grey wolves in the nature. The proposed algorithm is tested on IEEE 33-bus radial distribution system. The simulation results prove reasonable computing time and high performance of the proposed method comparing with other well-known optimization techniques.

In this paper, proposed optimization technique called whale optimization algorithm (WOA) is presents to find the optimum allocation of distributed generation (DG) and capacitor in radial distribution systems during reduction of single and multi-objective function namely, (network power losses, voltage deviation, and total operating cost). The multi objective function is formed by the use of weighted sum method. In this paper, multiple-DG units have been analyzed under two load power factors (i.e., unity and optimal) with and without capacitor (C). WOA technique has been applied to a 33-bus radial distribution system. The performance of the WOA technique is compared with other evolutionary optimization methods under different operating conditions of the system. The impact of integrating the proper size of DG and C at the suitable placement based on proposed algorithm are shown in the simulation results.

In this paper, a comparative analysis of using single-phase or three-phase voltage-sources for Space-Vector pulse-width modulation (SVPWM) three-phase inverter feeding a Permanent-Magnet (PM) servomotor is presented. In industrial applications, the three-phase voltage-source is commonly used and available. However, in sometimes the availability of three-phase voltage-source is not easy, permissions and facilities from service provider are required. These costs much money to make the three-phase voltage-source available. In small power applications, the single-phase voltage-source is sufficient to provide the required power and the three-phase voltage-source is not needed. The study compares the two cases from point of view of total harmonic contents of voltages and currents of the PM servomotor in each case. The results show that in case of using single-phase voltage-source, the total harmonic distortion of phase and line voltages is reduced by 42.689 %. The total harmonic distortion of load current is reduced by 45.32 % at half load and by 40.44 % at full load. Consequently, there is an improvement in the quality of the PM servomotor voltages and currents. The size of the harmonic filter is reduced and the drive system harmonic effect on the grid due to grid connection is reduced significantly.

Focus accuracy is an essential factor that affects the astronomical observations quality. The accurate measure of celestial objects properties depends on focus. Automatic focusing is necessary for astronomical observations imaging systems. This paper presents a modified focus measure operator. It also proposes the use of fuzzy logic, to transform images, because of its tolerant of imprecise and incomplete data. The focus operators are applied into two sequences of star clusters observations. The experimental results show that the suggested measure overall score exceeds the previous operators.

Over the last decade, indoor localization has been gaining increasing popularity in the research community. Since GPS offers high accuracy within the outdoor environment only, the vast proliferation of IoT-enabled devices within indoor environments can serve as an alternative to achieve GPS grade of accuracy for indoor positioning. IoT-enabled devices have already been shown to assist in forming several indoor positioning algorithms via several techniques. The centroid algorithm (CL) could be considered as one of the most popularly used algorithms for indoor positioning. In this paper, we propose a perpendicular distance-based approach (PD) that relies on the received signal strength indicator (RSSI). The proposed algorithm is theoretically analyzed. The RSSI-PD algorithm is simulated and its accuracy is evaluated in comparison with the developed versions of CL such as Weighted Centroid Localization Algorithm (WCL) and Weighted-Compensated Weighted Centroid Localization Algorithm (WC-WCL).

This paper discusses the effects of distribution generation (DG) on the recloser-fuse coordination of radial distribution systems. These effects are considered one of the disadvantages of connecting DGs with distribution systems and depend on the technology, location and size of DGs. Three different locations of DGs are studied: firstly, when the DG is located between the recloser and fuse, secondly, when the DG is located upstream of recloser and fuse, and thirdly, when the DG is located downstream of recloser and fuse. In every location the technology and size of the DG is varied and the penetration level at which the coordination is lost is recorded. The different studied technologies of the DGs are photovoltaic (PV), wind turbine of squirrel cage induction generator (Type 1) and wind turbine of synchronous generator (Type 4). The studied system is a radial distribution system consisting of 14 buses with main feeder and two laterals. All simulations are performed using ETAP 12.6.0 package. The results show that the recloser-fuse coordination may be lost as the size of DG increases, the worst location is when the DG is connected downstream to the recloser and fuse, and the worst DG technology is the Type 4 wind turbine.
