The development in the field of electrical energy has been growing increasingly due to the need for this energy in daily life. The reliability and safety of electrical power systems and equipment represent complex problems that are difficult to solve by conventional methods such as Fuzzy Logic and Artificial Neural Networks. Bayesian network is recently used to overcome some limitations in conventional methods. This pap Read More

Background: Surface permanent magnet motors (SPMVM) and dual permanent magnet motors (DPMVM) have broad prospects in direct drive systems, but some problems occur with large magnetic leakage, large torque ripple and large amount of permanent magnets (PMs). Objective: In order to reduce the torque ripple and magnetic flux leakage of SPMVM and DPMVM, and improve the torque density, a dual permanent Read More

Background: With the continuous development of big data, artificial intelligence, the Internet of things, and blockchain technology, distributed interactive systems have gradually become the mainstream of computing technologies and applications with the help of real-time interaction platforms. The real-time interaction platforms provide a data communication bridge for distributed applications, not only meeting the ti Read More

Aim: Improving the frequency regulation in a Low Voltage (LV) microgrid during grid mode transition using Grid Forming Grid Support (GFGS) converters with inertia emulation. Background: The ever-increasing demand for energy and the depleting fossil fuels has increased the proliferation of converter-fed Renewable Sources (RES) in the conventional grid. The reduced system inertia results in frequency regulation issues wh Read More

Background: Static Synchronous Compensator plays an essential role in governing the reactive power and harmonics of power systems. The accuracy and real-time performance of reactive power and harmonic detection are necessary to ensure balancing compensation effectiveness. The traditional dq current detection method can only extract positive sequence components in the positive sequence rotational referenc Read More

With the increase in the number of Electric Vehicles (EVs), more power will be needed from the grid. An increase in the load demand, losses, and grid operational costs will occur. Furthermore, with the increasing number of EVs, there comes a possibility of user dissatisfaction which can further lower the popularity of EVs. Objective: This article focuses on EV battery charging and discharging control optimization, i.e., optimizing lo Read More

Background: With the development of technologies such as the Internet of Things (IoT) and cloud/edge computing, a large number of edge devices in the smart grid accomplish information interconnection and generate massive amounts of data. On the one hand, smart grids need to obtain a large amount of grid data from edge terminal devices. On the other hand, edge computing also brings some security threats. Therefore Read More
