This paper analyses the load shedding methods for the impact of communication delays. Therefore, the research investigates the impacts and effects of communication networks in the grid systems which might cause imperfections such as delays and noise among others related to relays. The model of the power system and the design of the controllers are done using Simulink, the Matlab software. The controllers are designed to output power imbalance based on frequency deviation during various systems under frequency conditions. They also shed loads continuously until the frequency is restored within the safe operating range. Different cases of the system under frequency are used to analyze the performance of the grasshopper optimization algorithm (GOA) proposal based on under-frequency load Shedding UFLS, a comparison with Traditional and particle swarm optimization (PSO). UFLS is performed due to various disturbances. It has been found that a GOA method provides excellent communication networks and reduces the size of the load is shed. Moreover, and what’s more, GOA achieves the fastest solution we’ve ever used in IEEE 14 Bus system.

The coupling method used to superimpose and separate the data signal to and from the powerline plays a crucial role concerning the channel frequency response, the coupling efficiency, and also preserving the signal integrity against the peaks and notches caused by reflections, which will cancel certain carrier frequencies at the receiver. Furthermore, the coupling unit should be bi-directional to allow the signals coupling regardless the direction of data flow, likewise it needs to accomplish galvanic isolation together with transient protection, and offers more degrees of freedom to impedance-matching, as well as allocating less space and achieve high bandwidth for broadband coupling. This paper discusses an approach to pursue toward designing a printed-circuit board (PCB)-based planar coil inductive coupler with wide bandwidth for data transfer.The designed coupler will eventually be used to implement powerline communication (PLC) adequately for airborne use, where a real-case context study was investigated, also PLC implementation and tests were conducted as well as discussed from latency, bit error rate (BER) and electromagnetic compatibility (EMC) compliance perspective with the RTCA DO-160G standard requirements.

Ferrite is generally added to the transmitting and receiving coils used for inductive power transfer (IPT) to improve magnetic performance. To reduce coil weight and cost, finite element method (FEM) modelling may be employed to minimize the amount of ferrite used and optimize its placement. However, this approach is time-consuming and provides very limited design insight. Therefore, this paper proposes an analytical approach, based on magnetic reluctance, to aid in the design of IPT coils. It is based on modelling the air gap between transmitting and receiving coils as a network of reluctances, and facilitates design insight through allowing key analytical relationships between magnetic field and coil design parameters to be developed. Results from the proposed analytical model are benchmarked against those from FEM for an IPT coil implemented with a circular winding and with commonly used ferrite strips. The results verify the accuracy of the proposed analytical model.

For many distribution network operators (DNOs), the phases to which single-phase loads are connected is unknown. This can present a problem in terms of unbalanced loading across phases, which will be significantly exacerbated by the future impact of large-scale electric vehicle (EV) charging loads. In addition, the implementation of EV charging systems can give rise to the presence of significant harmonics on power systems, as a result of converter operation. Therefore, this paper proposes a fast EV charging technique that incorporates phase balancing and harmonic suppression features. This allows multiple and important functions that are necessary for the improved operation of a local distribution network to be achieved through the installation of a single unit. Consequently, units based on the proposed technique suit the large-scale and strategic deployment in distribution networks. The paper describes the technique in detail, presenting relevant theory and the control strategy. To demonstrate the applicability of the proposed technique, simulated results of a 50 kW fast EV charger are presented under various unbalanced load conditions.

Model predictive control (MPC) has been previously proposed as an effective solution to perform power control for neutral-point-clamped (NPC) converter-based wind turbine. However, the appropriate control of switching frequency and the tuning of the weighting factors in the cost function are challenging and the study of stability is intrinsically complicated. This paper presents a design guideline of MPC-based power control strategy for NPC converter-wind turbine with online tuning to optimize switching frequency. Furthermore, the dynamic response of the MPC system is evaluated at different operating points and grid impedances. The frequency-scanning technique is proposed to validate the stability of the system. Finally, simulation results are given to validate the proposed MPC strategy for NPC converter-based wind turbine.

The coexistence of electricity-driven train and hydrogen-driven train is becoming an important trend for future metro transportation. This article presents a novel electricity-hydrogen-integrated hybrid DC traction power system (HDCTPS) to integrate renewable microgrid, hydrogen subsystem and DC traction power system (DCTPS). A triple active bridge converter-based metro energy router is developed to integrate efficiently those three subsystems in HDCTPS. Then, the operation and control framework of HDCTPS is established, where the four operation modes are developed according to the power characteristic of renewable energy and regenerative braking operation of DCTPS. Power management and control strategy of HDCTPS are developed to perform smooth transition between different modes. Simulation results are given to validate the proposed HDCTPS and control framework. The proposed HDCTPS, as a novel operation strategy for future metro system, is able to utilize efficiently renewable energies and regenerative braking energy to achieve energy saving.

The most common Induction Motor (IM) faults discussed in literature are of three types, namely, bearing faults, stator faults, and rotor faults. These faults often result in unexpected failures or unplanned shutdowns of IMs. A reliable condition monitoring method, however, can ensure their safe and uninterrupted operation. The acoustic signal analysis is one of the effective condition monitoring techniques used to identify incipient faults in IMs while Artificial Intelligence (AI) technology has been widely integrated with Machine Learning (ML) algorithms to automate the machinery condition monitoring process. This paper reviews application of acoustic signal analysis to detect impending failures of IMs. Moreover, time domain and frequency domain analysis techniques and features that can be derived from raw acoustic data are also discussed in detail. The paper also presents intelligent condition monitoring systems that are developed to improve fault diagnostic accuracy and recent developments in acoustic signal analysis based condition monitoring of IMs.

In bidirectional Wireless power transfer (BDWPT) for electric vehicle battery chargers, aside improving efficiency, the effects of stray magnetic field on users and the general public is also of concern. Hence, the stray magnetic field and power loss are key performance indicators to be optimized. The optimization, reported in literature, is obtained with Pareto front which is derived by sweeping the physical parameters of the coil. This optimization is realized at the design stage. This work explores the optimization of these performance indicators from the control point of view and can be achieved on-line. The method discussed here involves the control of the duty cycle and displacement angles of the inverter and rectifier voltages to meet the objective of reducing the stray field and power losses. To this end, the classical Lagrange optimization procedure is employed to simultaneously minimize the stray magnetic field and power loss for a given output power condition.

In this paper a Single-Phase nine level inverter based on conventional single-phase H-bridge topology is proposed. It is dedicated to be used for ensuring the connection of single AC load to photovoltaic system. The proposed inverter system features less of switches number and a new auxiliary switches conception. Hence, it gives better voltage regulation, smooth operation and efficient yield compared to multi-level inverters. The proposed inverter topology is capable of producing nine levels of output voltage levels. This inverter is firstly simulated under MATLAB/ Simulink software, thereafter, co-simulated using the Processor-in-the-loop (PIL) technique. Secondly, the proposed inverter is designed and tested experimentally. The inverter control is implemented on the high-speed ARM-STM32F407 board. Based on the obtained results, it can be seen clearly that co-simulation results are matching experimental results, which proves the validity of the proposed multi-level inverter. This topology can be extended for more number of phases and levels.
