“…Mechanical ESSs include pumped hydroelectric storage, where energy is generated as potential gravitational energy; compressed air ESSs, which produce electricity using the pressure potential energy principle; and flywheel ESSs, which broadens as electromechanical systems of kinetic energy. 29,30 Concentrated solar thermal power storage technology is an instance of thermal storage. Many mirrors are located around the heating chamber; each reflects the sunlight.…”

Summary As the world's population and living standards rise, energy suppliers will face increased electrical energy needs. Furthermore, the European Commission has established a goal to reduce fossil fuel use and greenhouse gas emissions in accordance with the Kyoto and Paris Protocols. As a result, governments are more likely to integrate renewable energy into their electricity grids. However, since renewable energy resources are intermittent, power grid systems confront considerable hurdles. By overcoming the intermittency of renewable energy resources, battery storage systems are one way to optimize load and demand. Many studies show that the stored energy can be used in high demand. This may reduce the cost of production in the long run. Energy storage systems can also provide voltage and frequency regulation to power systems when connected to the transmission and/or distribution lines. The application and benefits of battery storage devices in electricity grids are discussed in this study. The pros and disadvantages of various electrochemical batteries, including their structure, energy capacity, and application areas, are compared and summarized and their benefits and drawbacks are included. Finally, the research demonstrates how electrochemical battery technologies and power grids have collaborated.

“…Also noteworthy, motor power is capable of producing safe and long-term energy in 24 h cycles because the power is unconstrained in terms of technology, location, and generation environment. This is especially true when this new technological innovation is applied to the electromagnetic power system or magnetic bearing to the machine shaft to reduce friction in the rotation system [13,[80][81][82][83][84][85]. It also reduced energy consumption in the system by almost 50% [1] and led to electrical energy in the system.…”

Electricity has become one of the most important factors contributing to both the livelihoods of individuals and global economic development. Most electricity generation is still derived from burning fossil fuels that contribute to environmental degradation. The aim of this research, through innovative design, was to create clean circular technology through the utilization of electronic devices that control and send optimally timed commands to two 72-volt batteries (DC) that store and distribute energy. This new form of electric power generation was adapted to be used with a three-way differential gear system. The speed of transmission was adjusted, and shaft rotation was connected to a 7.5 kw/h DC power motor with two 15 kw/h alternators in three phases to generate high torque power at the desired rate of 3000 RPM and electricity. The first set of alternators generated the electrical energy to be distributed. The circuit system of battery set one was used for storage and slowly fed to the motor, which was kept continuously running for hours. The second alternator distributed the generated voltage to the secondary battery, which stored backup power and provided the main power to the grid. This system is especially appealing for those looking to improve energy efficiency and contribute to the green economy, as this system can be applied to power charging stations for electric vehicles or used as a backup power source for buildings.

“…Compared to normal rotary machines supported by mechanical bearing, the magnetically suspended rotary machine with stable suspension of active magnetic bearing (AMB) [1,2] has advantages of contactless suspension, free-lubrication, micro-vibration and active controllability. Therefore, to improve the dynamic performance and service period of rotary machines, the AMB has been widely used in many kinds of rotary machines, such as the momentum flywheel for satellite altitude control [3,4], the flywheel energy storage system (FESS) [5,6] and the high energy density motor [7,8].…”

An air-blower with active magnetic bearings could improve working efficiency and reduce energy consumption by avoiding contact between the rotor shaft and the stator part. The structure and prototype of a magnetically suspended air-blower are herein introduced, and the force models of active magnetic bearings developed. Furthermore, the dynamic models of a rotor shaft with unbalance terms were established to investigate the vibration characteristics of the magnetically suspended air-blower. The vibration characteristics of the rotor shaft with unbalance terms were analyzed, and the complex-field cross-feedback control was designed to suppress the vibration amplitude. Finally, experiments were conducted to verify the theoretical models, and the results indicated that the vibration amplitude of the rotor shaft with unbalance terms could be intensified by the rotating frequency, and the nutation vibration was reduced by 50% through increasing the high-frequency nutation coefficient of the complex-field cross-feedback control model. The results indicated that the vibration analysis of the rotor shaft was meaningful to the design and control of the magnetically suspended air-blower.
