Superconducting inductors provide a compact and efficient means of storing electrical energy without an intermediate conversion process. Energy storage inductors are under development for load leveling and transmission line stabilization in electric utility systems and for driving magnetic confinement and plasma heating coils in fusion energy systems. Fluctuating electric power demands force the electric utility industry to have more installed generating capacity than the average load requires. Energy storage can increase the utilization of base-load fossil and nuclear power plants for electric utilities. The Los Alamos Scientific Laboratory and the University of Wisconsin are developing superconducting magnetic energy storage (SMES) systems, which will store and deliver electrical energy for load leveling, peak shaving, and the stabilization of electric utility networks. In the fusion area, inductive energy transfer and storage is being developed. Both 1-ms fast-discharge theta-pinch systems and 1-to-2-s slow energy transfer tokamak systems have been demonstrated. The major components and the method of operation of a SMES unit are described, and potential applications of different size SMES systems in electric power grids are presented. Results are given of a reference design for a 10-GWh unit for load leveling, of a 30-MJ coil proposed for system stabilization, and of tests with a small-scale, 100-kJ magnetic energy storage system. The results of the fusion energy storage and transfer tests are presented. The common technology base for the various storage systems is discussed.

Long-time varying-daily, weekly, and seasonal-power demands require the electric utility industry to have installed generating capacity in excess of the average load. Energy storage can reduce the requirement for less efficient excess generating capacity used to meet peak load demands. Short-time fluctuations in electric power can occur as negatively damped oscillations in complex power systems with generators connected by long transmission lines. Superconducting inductors with their associated converter systems are under development for both load leveling and transmission line stabilization in electric utility systems. Superconducting magnetic energy storage (SMES) is based upon the phenomenon of the nearly lossless behavior of superconductors. Application is, in principal, efficient since the electromagnetic energy can be transferred to and from the storage coils without any intermediate conversion to other energy forms. Results from a reference design for a 10-GWh SMES unit for load leveling are presented. The conceptual engineering design of a 30-MJ, 10-MW energy storage coil is discussed with regard to system stabilization, and tests of a small scale, 100-KJ SMES system are presented. Some results of experiments are provided from a related technology based program which uses superconducting inductive energy storage to drive fusion plasmas.

This book explores the potential of magnetic superconductors in storage systems, specifically focusing on superconducting magnetic energy storage (SMES) systems and using the Spanish electricity system, controlled by Red Eléctrica de España (REE), as an example. The book provides a comprehensive analysis of the economic costs associated with the manufacture and maintenance of SMES systems, as well as a regulatory analysis for their implementation in the complex Spanish electrical system. The analysis also compares this system with the regulations of other countries, providing a comprehensive case study. The book examines the possible economic and environmental benefits of using magnetic superconductors in electrical systems and provides a technical study of the use of these systems in hybrid storage systems that complement each other to optimize network performance. The study is conducted from the perspective of new distribution networks, distributed generation, and the concepts of the smart city. The book also explores potential applications and developments, such as electric vehicles. Overall, this book offers an insightful and comprehensive analysis of the potential of magnetic superconductors in storage systems. It will be an invaluable resource for researchers, engineers, and policymakers interested in the future of energy storage systems

Superconducting magnetic energy storage (SMES) systems differ from other storage systems presently in use, or considered for use, by the electric utility industry, principally because of the radically different technology involved. SMES also has certain unique advantages: it appears to be able to store and deliver energy at very high efficiency, and it can switch from the charge to discharge mode in a few tens of milliseconds. The combination of these two desirable characteristics distinguishes SMES from almost all other energy storage systems. This investigation was undertaken to discover if the nation and the electric utility industry might benefit sufficiently from the use of SMES systems to justify continued research and development support by DOE. At present, systems development is in a relatively early stage, and much component development for many of the major subsystems remains to be performed. It appears each SMES unit will be large and therefore expensive; also that the investment in research and development required to achieve final commercial success may be substantial.

This international conference was organized by the sponsoring agencies with the following objectives in mind: to bring together active researchers involved in energy compression, switching, and storage who have a major interest in plasma physics, electron beams, electric and magnetic energy storage systems, and high voltage and high current switches. Areas of interest include: Slow systems: 50-60 Hz machinery, transformers, flywheel-homopolar generators, slow capacitors, inductors, and solid state switches. Inter mediate systems: fast capacitor banks, superconducting storage and switch ing, gas, vacuum, and dielectric switching, nonlinear (magnetic) switching, 5 6 fast (10 - 10 Hz) capacitors and fuses. Fast systems: Marx, Blumlein, oil, water, and pressurized water dielectrics, switches, magnetic insula tion, electron beams, and plasmas. The Editors extend thanks to all the authors, and attendees (and their supporting institutions, and companies), everyone of whom in his own measure helped to make the conference a success. The Editors further wish to thank the members of the Scientific Committee for the help they have given in organizing the conference and in editing, especially J. C. Martin and H. L. Laquer. Special recognition is due the Lawrence Livermore Laboratory whose Electrical Engineering Department provided the Secretary of the Scientific Committee and one of the Editors, and the yeowoman services of Sharon Dodson and Cheri Johnson in all the mailings, correspondence, and receiving and organizing of the manuscripts. The LLL Technical Information Department provided the design and printing of the conference announcements and the instructional formats for the authors' manuscripts.
