Optimization scheme of superconducting magnetic energy storage system

What is superconducting magnetic energy storage (SMES)?

The use of superconducting magnetic energy storage (SMES) is becoming more and more significant in EPS, including power plants, T&D grids, and demand loads [8, 9]. Delivering power to demand loads is, in general, the main goal of EPSs .

Can superconducting magnetic energy storage technology reduce energy waste?

It’s found that SMES has been put in use in many fields, such as thermal power generation and power grid. SMES can reduce much waste of power in the energy system. The article analyses superconducting magnetic energy storage technology and gives directions for future study. 1. Introduction

What is a superconducting system (SMES)?

A SMES operating as a FACT was the first superconducting application operating in a grid. In the US, the Bonneville Power Authority used a 30 MJ SMES in the 1980s to damp the low-frequency power oscillations. This SMES operated in real grid conditions during about one year, with over 1200 hours of energy transfers.

Can superconducting magnetic energy storage reduce high frequency wind power fluctuation?

The authors in proposed a superconducting magnetic energy storage system that can minimize both high frequency wind power fluctuation and HVAC cable system's transient overvoltage. A 60 km submarine cable was modelled using ATP-EMTP in order to explore the transient issues caused by cable operation.

Is SMEs a competitive & mature energy storage system?

The review shows that additional protection, improvement in SMES component designs and development of hybrid energy storage incorporating SMES are important future studies to enhance the competitiveness and maturity of SMES system on a global scale.

Why does SMEs have a short energy storage duration?

SMES has a short energy storage duration because it shows a very high self-discharge ratio of 10-15% per day. SMES has a low energy density which is only about 0.5-5Wh/kg. The energy content of current SMES systems is very small. Ways to increase the energy storage capacity of SMES are often to use large energy storage units.
