Superconductive energy storage for power systems

Abstract

Abstract-The use of large superconducting inductors for "pumped" energy storage as an alternate to pumped hydrostorage is discussed. It is suggested that large units might be developed at less than $20O/kW and with losses less than the 50 percent representative of pumped hydrostorage. Particular notice is taken of the ability of such peaking units to damp overall power system electromechanical oscillations.

Feasibility of Superconducting Magnetic Energy Storage on Board of Ground Vehicles With Present State-of-the-Art Superconductors

“…Such a system is referred to as SMES. The feasibility of SMES by means of low-temperature superconductors (T c = 10−18 K) was demonstrated back in the early '70s [7]. After their discovery in 1986, a great research effort was carried out to develop SMES systems based on high-temperature superconductors (HTSs, T c > 92−107 K) [8].…”

Energy storage systems for advanced power applications

“…Although superconductivity was discovered in 1911, it was not until the 1970s that SMES was first proposed as an energy storage technology for power systems [1]. SMES systems have attracted the attention of both electric utilities and the military due to their fast response and high efficiency (a charge-discharge efficiency over 95%).…”

Power oscillation suppression by robust SMES in power system with large wind power penetration

“…To overcome this problem, a superconducting magnetic energy storage (SMES), which is able to supply and absorb active and reactive power simultaneously [7,8], can be applied. In the past, SMES has been used to solve many problems in power systems such as an improvement of power system dynamics [9,10], a frequency control in interconnected power systems [11,12], an enhancement of power quality [13], a stabilization of sub-synchronous oscillation in the turbine-generator [14], a load leveling [15], etc.…”
