Microgrids have lately been employed in power systems to improve reliability and power quality. This paper shows the dynamic modeling and control of a hybrid grid-connected microgrid consisting of a photovoltaic plant, energy storage system, DC loads, and AC loads. The microgrid is provided with a hydrogen storage system consisting of an electrolyzer, a fuel cell, and a Hydrogen tank. The microgrid is designed to operate independently and supply the load in case of a grid outage. Both grid-connected and isolated modes are modeled using the Simulink software package and it is concluded that the control systems of the microgrid efficiently delivered the required energy to loads in both modes while keeping the microgrid stable. This paper proposes that hybrid-AC/DC microgrids are capable of increasing power flow systems efficiency, increasing the deployment of distributed generation, and being independent of the grid if needed.

The effect of Greenhouse Gases on the environment has been increasing rapidly. In attempts to reduce pollution and the consequent Greenhouse effect, electric vehicles were introduced. For short travels, cheaper and greener alternatives such as electric smart bikes are becoming a hype. E-bikes are convenient, however, improving the modules available to better suit Smart E-bikes can make it more convenient for the users. The State of Charge (SOC) of the battery is an example. An accurate estimation of the SOC in an E-Bike is important, however, it cannot know if the current path selected by the rider will be covered fully by the remaining battery power. To make the available E-Bike modules smarter, battery estimation-path traversal in this case, this paper proposes a battery energy estimation system that notifies the rider if their chosen route is within the range that the current battery state can handle. This safety feature insures that users will always have power when traversing an approved route by the estimation system. In addition, the system is tested on a real-life prototype smart autonomous E-Bike to validate the results of the proposed approach.

Photovoltaic systems (PV) are exposed to various weather conditions during the day and getting the maximum power of a PV system is one of its major challenges. While the conventional methods take time to track the maximum power accompanying the fluctuation around the maximum power. Consequently, several metaheuristic algorithms have been presented to overcome the fluctuating around the maximum power. On the other hand optimization methods will search into entire the PV curve to extract the maximum power. This leads to unnecessary search points during the uniform shading conditions which decrease the convergence speed towards the maximum power. In overcoming the tracking time issues as well as the capacity to distinguish between uniform and partial shading conditions, a quick and efficient tracking technique connected to the grid system was presented in this paper. The proposed system, has been tested using MATLAB/SIMULINK, which includes a boost converter to track the maximum power with a sampling time of 0.05 seconds, While a voltage source converter (VSC) is used to transfer the power generated by solar panels to the grid. The simulation results demonstrated that the proposed method was successfully implemented, with an average tracking time of 0.412 s for different weather conditions. Moreover, the comparison with the conventional method of perturb and observe (P& O) has been presented to evaluate the proposed method’s efficiency.

Partial Discharge (PD) is one of the biggest factors that cause the breakdown of cables in both high voltage alternating current (HVAC) and high voltage direct current (HVDC). In comparison to AC insulation systems, the behavior of PD is significantly more complex in DC insulation systems, especially in HVDC Cross-linked Polyethylene (XLPE) power cables. Since PD activities are essentially a result of increased electrical stress under loaded conditions, the distribution of temperature, electrical fields, and PD inception all become large contributors to cable aging. The goal of this paper is to evaluate the PD inception voltage (PDIV) in HVDC power cables and to compare their XLPE insulation performance under high DC voltage and thermal stresses. The impact of the void’s size and position on the PD inception voltage is also investigated. The correlation with the shape and the size of the voids in DC insulation system and the PD inception voltage will be found. The paper will also show how the PDIV is dependent on temperature under the investigated circumstances. This study is conducted using Finite Element Analysis (FEA) software (COMSOL Multiphysics).

In this paper, the design and extensive analysis of an advanced test rig for double pulse tests (DPT) is presented. Unlike the simplistic analysis that is usually done whilst designing a DPT circuit, in this work, the analysis critically considers the effects of parasitics in the capacitor, inductor, PCB fixtures, and the device under test (DUT), to attain the highest measurements accuracy. The model for the proposed system is simulated using a SPICE simulation tool, which considers all the parasitics and demonstrates the feasibility of optimizing the design parameters. Then, the physical test rig is implemented following the proposed approach to reduce the parasitic inductance between the DC-link capacitors and the fixture. The rig is designed to be flexible, where different fixtures with low parasitics can be used to connect discrete and module DUTs. The measurement circuitry is carefully optimised, to provide the ability of capturing the high dI/dt and dV/dt of wide bandgap (WBG) devices. The system can also provide temperature control via a heater and a temperature controller, so the variation of switching losses with junction temperature can be assessed. The results validate the feasibility of the design, where low ringing and low voltage overshoot in the waveforms have been obtained, easing the switching losses calculations, even with low gate resistors. Finally, a 1. 2kV/90 A rated silicon carbide device has been tested, and its switching energy has been evaluated at different junction temperatures to demonstrate the capabilities of the system.

Nowadays, DC microgrids control problems are considered as attracting challenges for the researchers. Thus, a distributed control strategy is presented in this paper for meshed DC microgrids enhancement. The strategy consists of two control layers, a primary control layer and a secondary control layer. The primary controller regulates the terminal voltage of each Distributed Generator Unit (DGU), while the secondary controller takes the responsibility of achieving equal current sharing between DGUs. Two Adaptive PI Controllers (APICs) are proposed for the secondary control layer to enhance the dynamic performance of the system. Validation of the proposed controllers is done under different loading conditions to show the improvement of the current sharing using the adaptive controllers.

This paper presents the design, training, and implementation of a Feed-Forward Neural Network based on Model-Free Predictive Torque Control (MF-PTC) to control an Induction Machine (IM) powered by a two-level Voltage Source Inverter (2L-VSI). This control uses an algorithm capable of estimating the dynamic behavior of an IM without having a detailed knowledge of the system using the past measurements of the control variables (stator currents and flux) and input variables (stator voltages). With this approach, it is possible to design a neural network that mimics the behavior of this control just by measuring the current and estimating the flux. The control topology, neural network architecture, network training, and implementation are detailed in this work. Simulation results are presented for different operating points of the machine to validate the performance of the proposed strategy.

Series-connected wound-rotor induction motor (SCWRIM) provides an electromechanical torque in two modes of operation. In the first mode, the rotor speed is exactly equal double the synchronous speed. With absence of inherent starting torque capability, the rotor speed in this mode only depends on supply frequency and number of poles for stable range of operation. In the second mode of operation, SCWRIM rotates at slightly less than the synchronous speed depending on the connected machine load. Therefore, this operation is known as sub-synchronous mode. In this mode, the motor has the capability of self-starting, and it runs in a similar manner to that of the conventional wound rotor induction motor operation. The influence of magnetic saturation and iron losses on steady-state performance of SCWRIM in sub-synchronous mode is examined theoretically and experimentally in this paper. The motor behavior has been investigated with considering magnetic saturation effect on both direct (d) and quadrature (q) axes flux linkages. The performance investigation has included the effect of magnetic saturation and iron losses at variable values of voltages and frequencies using scalar control technique via a variable voltage variable frequency (VVVF) supply. Finally, the simulation results are compared with experimental measured values to show the effectiveness and accuracy of the proposed approach of including magnetic saturation and iron losses effects.

High inductance-density with high saturation current on-chip integrated power inductors support achieving high-density integrated power conversion. To guide the design of on-chip planar power inductor, a 3-D physical model in ANSYS®/Maxwell® is developed and utilized in this paper to evaluate the effect of copper winding number of turns on two of the main power inductor performance metrics, namely the inductance value/density and the saturation current. The tradeoff between the inductance value/density and the saturation current as a function of the copper winding number of turns is evaluated using the presented physical model.

Isolated multi-port converters can interconnect different loads and energy sources at their ports, while utilizing a limited number of switching devices and magnetic components, which offers potential advantages in terms of power density. However, being the multiple ports coupled among each other, the number of modulation variables and operating modes increases, which poses challenging optimization issues. This paper exploits three different optimization approaches used to optimize the performance of a triple active bridge converter (TAB) by minimizing the ports total true rms current. The three approaches shown herein are based on an offline gradient descent search, online multidimensional ripple correlation search, and artificial neural network. All the approaches are validated through simulation and experimental results considering a TAB converter prototype rated 5 kW.
