Model predictive control is an exciting control technique that has been applied successfully to multiphase induction machines. The possibility to include several constraints by using only the cost function is one of its main attractive characteristics. However, this latter implies the nontrivial task of adequately tuning the weighting factors to fulfil multiple control objectives properly. This paper proposes a sequential model predictive torque control of a six-phase induction machine that avoids using the weighting factor. Simulation studies are provided to show the effectiveness of this proposal showing good reference tracking of the torque, flux and stator $alpha-beta$ and $x-y$ currents.

The concept of vehicle-to-grid (V2G) has been applied to residential microgrids (MGs) to play an essential role in regulating terminal voltage and system frequency. For this purpose, a power system stabilizer (PSS) has been selected, which is added to the excitatory system to enhance the dynamic and transient stability performance and to offer damping characteristics adequate for V2G regulation. In this work, three interconnected areas powered by diesel generators are investigated to measure the effectiveness of the proposed V2G scheme with PID-PSS controller that is adapted in a direct manner compared to the conventional MGs without the V2G scheme. The studied islanded residential MGs are consisting of diesel generators that are used as main generation sources, residential loads, and EVs aggregator. The performance of the proposed scheme is examined under the effect of a $3-emptyset$ short circuit fault between areas 1 and 3. The final findings emphasize the superiority of using V2G with adaptive PSS compared to the conventional system without both PSS and the inclusion of V2G in terms of over/undershoot and settling time ‘stabilizing faster’.

Nowadays, many households are adopting distributed energy resources (DERs), such as photovoltaics (PV) systems and energy storage systems (ESS) which enable each house to generate and consume energy. Peer-to-peer (P2P) energy trading is a new energy trading management among prosumers and consumers in the distribution power system, allowing excess energy to be traded locally. This work aims to design and implement an oracle blockchain-based system for local energy trading among smart homes in a microgrid. The main focus is the interaction between distributed P2P networks such as blockchain and oracle networks. Our implementation consists of a private Ethereum blockchain network and a Chainlink oracle network. Smart contracts enable prosumers and consumers to trade energy in an open auction while requesting external energy data from our testbed API through the oracle network for the settlement process.

Renewable energy sources (RESs) can reduce carbon footprint, meet the increase in load demand, and reduce losses at low running cost. Microgrids, incorporating RESs, have several challenges concerning power quality, protection schemes, and control especially in island mode. This paper focuses on presenting the power sharing problem and different factors affecting it. In addition, it presents different control trends to overcome this problem. The presented control techniques are based on droop control as it is simple, communication-less, reliable, and allow the parallel operation of RESs. Finally, a comparison between these techniques is conducted in terms of controller response time, controller transient overshoot and THD. Another comparison is included to reveal main features, advantages, and disadvantage of different techniques.

In the world, there are more than one billion people who have not accessed to electricity. IEEE Empower a Billion Lives has been initiated. The goal is to provide at least Tier 2 electricity access that is defined by ESMAP (Energy Sector Assistance Program). For a solution, the Solar Off-grid System (SOS) is introduced in this paper. It is the system that has a microinverter and lithium-ion battery pack integrated at the back of photovoltaic (PV) panel. The optimum PV panel power and battery capacity are simulated by considering eight power flow scenarios. As a result, the optimum size for PV panel is 60W and the battery capacity is SOWh. Then, the state-of-charge (SoC) estimation method is explained based on the battery modeling, and its parameters are experimentally extracted. After that, a thermal management strategy is discussed and decided to be PCM (Phase Change Material) by considering a PV temperature model and a battery thermal model. Thus, this paper presents an optimized PV energy system for Tier 2 electricity access by researching its feasibility by adding theoretical and experimental results to make the system safe and cost effective.
在世界上，有超过10亿人没有用上电。IEEE Empower a Billion Lives已经启动。目标是至少提供ESMAP(能源部门援助计划)定义的第2级电力接入。为此，本文介绍了太阳能离网系统(SOS)。该系统将微型逆变器和锂离子电池组集成在光伏(PV)面板的背面。考虑八种潮流情况，对光伏板的最佳功率和电池容量进行了仿真。因此，光伏板的最佳尺寸为60W，电池容量为SOWh。在此基础上，阐述了基于电池模型的荷电状态估计方法，并对其参数进行了实验提取。在此之后，通过考虑PV温度模型和电池热模型，讨论并确定了相变材料(PCM)的热管理策略。因此，本文提出了一种优化的二级电力接入光伏能源系统，并结合理论和实验结果对其可行性进行了研究，以保证系统的安全性和成本效益。

Cryogenic cooling of a power electronics converter can considerably enhance the efficiency and power density of a power electronic conversion system utilized in all-electric ships and aircraft applications. However, there is a scarcity of literature that explores the performance operation of power electronic converters at cryogenic temperatures. Moreover, the performance of input-side capacitors at cryogenic temperatures is mysterious. In this context, this paper proposes a high-frequency pulsating DClink inverter for capacitor-less isolated three-phase applications to be used in aircraft cryogenically cooled power converters. The system comprises a high-frequency isolated DC/DC dual active bridge (DAB) converter as a pulsating DC-link followed by an active neutral-point clamped (ANPC) multilevel inverter for the DC/AC conversion stage. The issue behind proposing such an inverter is presented, and then the operation and control strategy of this inverter topology have been demonstrated. Finally, simulation results confirming its operation have been evaluated.

the paper presents the impacts of installing optimized PI controlled flexible AC transmission systems (FACTS) devices to improve voltage and angle stability of power systems. In the study static VAR compensator (SVC) is considered. The Henry Gas Solubility Optimization HGSO algorithm is applied to determine the optimum parameters of the proportional plus integral (PI) controller for SVC. Two different types of faults are considered to investigate the feasibility of installing optimized SVC devices in power systems to improve both angle and voltage stability. Three-phase short circuit fault is implemented at the generator terminals, and input mechanical disturbance are applied. The response indicate the superiority of the suggested HGSO controller over the conventional PI controller. Matlab software is used to solve the system equations.

This paper presents the Phase Locked Loop (PLL) nonlinear control design problem for power electronics applications. The paper proposes a new design method that transforms the whole solution to be a simple linear control problem of tracking a ramp. This completely solves the PLL pulling out of synchronism issue and the dependency of locking time on how close the PLL initialization speed is to the actual speed. This allows the PLL to have a faster tracking of the speed while increasing the system’s immunity to harmonics at the same time. Different design methods for PLL controller gains tuning are also discussed along with the linearization approaches in the literature. The proposed technique is then compared to different designs in the literature where the superiority of the newly proposed technique is proven and highlighted.

Partial Shading (PS) substantially affects the energy produced from the solar PV array where multiple maximum power points (MPPs) are clearly manifested on the P-V characteristic curves. These MPPs involve multiple local peaks (LPs) in addition to a unique global peak (GP). Due to the complex nonlinear PV characteristics curves that are produced under the PS phenomenon, conventional MPP tracking (MPPT) techniques are not capable for tracking the GP and may be trapped in LP. Therefore, it is essential to utilize sophisticated MPPT techniques based on AI techniques to successfully trace the GP. In this manuscript, two metaheuristic techniques for MPPT are investigated based on the Flower Pollination Algorithm (FPA) in addition to the Deterministic Particle Swarm optimization Algorithm (DPSOA). A comparative study has been performed to assess the dynamic performance of the PV array under various PS patterns. Based on the simulation results, both techniques can successfully trace the GP with rapid convergence speed and zero failure rate. Despite the FPA is capable for following the GP, the DPSOA is superior with lower convergence speed and less steadystate oscillation around the GP.
