The status of magnetoelectric technology in energy storage

What is a magnetoelectric material?

Magnetoelectric material exhibit interconnections of magnetic and electric field. ME applications can be classified as direct coupling and converse coupling. There are various ME devices including sensor, antenna and microwave devices. ME devices show better performance and the potential to be miniaturized.

How is energy stored in a SMES system?

In SMES systems, energy is stored in dc form by flowing current along the superconductors and conserved as a dc magnetic field . The current-carrying conductor functions at cryogenic (extremely low) temperatures, thus becoming a superconductor with negligible resistive losses while it generates magnetic field.

Is super-conducting magnetic energy storage sustainable?

Super-conducting magnetic energy storage (SMES) system is widely used in power generation systems as a kind of energy storage technology with high power density, no pollution, and quick response. In this paper, we investigate the sustainability, quantitative metrics, feasibility, and application of the SMES system.

Can superconducting magnetic energy storage (SMES) units improve power quality?

Furthermore, the study in presented an improved block-sparse adaptive Bayesian algorithm for completely controlling proportional-integral (PI) regulators in superconducting magnetic energy storage (SMES) devices. The results indicate that regulated SMES units can increase the power quality of wind farms.

Can a superconducting magnetic energy storage unit control inter-area oscillations?

An adaptive power oscillation damping (APOD) technique for a superconducting magnetic energy storage unit to control inter-area oscillations in a power system has been presented in . The APOD technique was based on the approaches of generalized predictive control and model identification.

Are in-plane magnetic anisotropy devices more energy efficient?

In-plane magnetic anisotropy devices are both slower and less energy efficient than perpendicular magnetic anisotropy. Spin-diffusion writing and spin Hall effect (SHE) memory are more energy efficient because they require a smaller voltage due to a lower resistance writing path.
