Short-Term Load Forecasting Method
Electricity consumption varies in short-, medium-, and long-term periods, which cover three forecast time horizons. They range, respectively, from one hour to a week, one week to a year, and more than a year. They are based on several factors, such as climate, region, and sector (residential, industrial, commercial). Residential loads consume most of the electricity generated. Short-Term Load Forecasting (STLF) is important for cost reduction, energy savings, fine scheduling, and safety assurance.

Artificial Intelligence in Microgrid Control and Safety
Cyber attacks in microgrid systems not only cause issues with data integrity and confidentiality, but cause huge economic losses. Communication of sensor and operational data between each node is essential to attain the efficient operation of microgrid systems. Therefore, monitoring and analyzing the data continuously plays a major role in attaining data integrity. This becomes challenging when the attack is made at the device level rather than the network level. In this scenario, the basic network-level security used in the classical CPS fails to identify the attacks.  Artificial Intelligence (AI) can detect and mitigate cyber attacks.

Streaming Electrification of Different Insulating Fluids
The comparison of different techniques used to assess the charging tendency of fluids is discussed depending on the flow type (planar or centrifugal), volume of oil, and interface material. The charge separation between the insulating fluid and metallic/pressboard interfaces is explained in terms of the electrical double layer formation involving a fixed layer and diffuse layer. Based on the experimental results, the streaming electrification is observed to be a function of various factors such as speed, temperature, electric field, and surface roughness. Depending on the molecular structure of insulating liquids that come into contact with solid insulation at the interface, the streaming current can increase; hence, a suitable additive (benzotriazole, fullerene, Irgamet 39) is selected based on the type of fluid and charge polarity. The degradation of the insulating liquid upon ageing, which increases the streaming current and reclamation of such aged fluids using adsorbents (Fuller’s earth, activated carbon, bentonite, and alumina), is a possible method to suppress the static current through improving its dielectric properties. The nanofluids show a higher streaming current compared to base fluid with no change observed even after the reclamation process.

Ka-Band Power Amplifier
With the increase in the demand for high-speed transmission communication, satellite communication is developing rapidly. Because of the bandwidth capacity, the K/Ka band is considered the mainstream frequency band of satellite communication. The performance of a power amplifier (PA) directly affects the power of the transmitter, so the application of a power amplifier in Ka-band satellite communication is very important.

Carbon-Coated SiO2 for Li-Ion Batteries
Li-ion battery technology is at the core of the imminent massive vehicle electrification due to the forecast growth penetration rate of electrified vehicles. In this cutting-edge Li-ion battery technology, silicon seems to be the most promising candidate for next-generation Li-ion battery technology due to its high theoretical capacity of 4200 mAh·g−1 (compared to 372 mAh·g−1 for graphite). Shifting to silicon as an anode material has the potential to deliver higher energy density for the batteries. The anode of a Li-ion battery should operate at low potentials and offer high specific energy capacity and density.

Deep Learning and Non-Orthogonal Multiple Access System
In a non-orthogonal multiple access (NOMA) system, the successive interference cancellation (SIC) procedure is typically employed at the receiver side, where several user’s signals are decoded in a subsequent manner. Fading channels may disperse the transmitted signal and originate dependencies among its samples, which may affect the channel estimation procedure and consequently affect the SIC process and signal detection accuracy. Machine learning (ML) algorithms have the capability to adapt to variations in channel between user and base station (BS); therefore, ML is regarded as a strong contender for future radio networks.

Load Frequency Control Considering Renewable Energy Sources
The hybrid power system is a combination of renewable energy power plants and conventional energy power plants. This integration causes power quality issues including poor settling times and higher transient contents. The main issue of such interconnection is the frequency variations caused in the hybrid power system. Load Frequency Controller (LFC) design ensures the reliable and efficient operation of the power system. The main function of LFC is to maintain the system frequency within safe limits, hence keeping power at a specific range. An LFC should be supported with modern and intelligent control structures for providing the adequate power to the system.

Applications of Coupled Bulk Acoustic Wave Resonators
There are two basic types of acoustic waves: SAW and BAW. When the acoustic wave is confined and travels at the interface between the substrate and the air, it is called a surface acoustic wave (SAW), like the ripples observed on the water surface hit by a stone. In contrast, a wave that propagates in the bulk of the material of the medium and exists in most of the volume of the media, is called a bulk acoustic wave (BAW), like a sound wave that travels through the air.

Direct Torque Controllers in Five-Phase Electrical Drives
Machines with more than three phases are called multiphase machines, which provide a better current distribution among phases, and lower current harmonic production in the power converter, than conventional three-phase machines. However, multiphase drive applications require the development of complex controllers to regulate the torque (or speed) and flux of the machine. In this regard, direct torque controllers have appeared as a viable alternative due to their easy formulation and high flexibility to incorporate control objectives.

Grid-Forming Inverters
The electrical grid is predominantly characterized by synchronous generators (SGs). These generators provide a consistent voltage and frequency, facilitating the synchronization of VSIs and their connection at the point of common coupling (PCC) for injecting power into the main grid. These inverters operate as current sources and are known as grid-following inverters. The imperfections of grid-following inverters arise when the grid is absent, as this concept fails to produce instantaneous voltage and frequency set points. Therefore, this operating mode has been significantly modified, from following the grid to leading it. This concept is known as grid-forming (GFM) inverters, which can independently set up and keep the voltage and frequency within their nominal ranges without the need for the main grid.

High Temperature Superconducting Flux Pumps for Contactless Energization
The development of superconducting technology has seen continuously increasing interest, especially in the area of clean power systems and electrification of transport with low CO2 emission. Electric machines, as the major producer and consumer of the global electrical energy, have played a critical role in achieving zero carbon emission. The superior current carrying capacity of superconductors with zero DC loss opens the way to the next-generation electric machines characterized by much higher efficiency and power density compared to conventional machines. The persistent current mode is the optimal working condition for a superconducting magnet, and thus the energization of superconducting field windings has become a crucial challenge to be tackled, to which high temperature superconducting (HTS) flux pumps have been proposed as a promising solution. An HTS flux pump enables current injection into a closed superconducting coil wirelessly and provides continuous compensation to offset current decay, avoiding excessive cryogenic losses and sophisticated power electronics facilities.
