Superconducting magnetic energy storage systems for power system applications

-In the reliability-based design optimization of electromagnetic devices, the accurate and efficient reliability assessment method is very essential. The first-order sensitivity-assisted Monte Carlo Simulation is proposed in the former research. In order to improve its accuracy for wide application, in this paper, the second-order sensitivity analysis is presented by using the hybrid direct differentiation-adjoint variable method incorporated with the finite element method. By combining the second-order sensitivity with the Monte Carlo Simulation method, the second-order sensitivity-assisted Monte Carlo Simulation algorithm is proposed to implement reliability calculation. Through application to one superconductor magnetic energy storage system, its accuracy is validated by comparing calculation results with other methods.

There is no doubt that power reliability in most nations of the world has increased. Over the years, electric power has grown beyond providing utilities to being a dominant and fundamental part of civilization with smart phones, electronic vehicles, personal computers, etc. In order to meet the power demands of a growing economy, energy losses need to be minimized along transmission and distribution lines from power generation to the inal load. This chapter discusses renewable energy sustainable solutions and superconducting power applications as a possible solution for energy sustainability, the environmental impacts of sustainable and superconducting technology with their future trends. It introduces smart grid and its roles in sustainability.

“…The second involves more recent high-speed flywheel systems (up to 60,000 rpm) that are available commercially and make use of advanced composite wheels that have a much higher energy and power density than steel wheels. This technology requires ultra-low friction bearing assemblies, such as magnetic bearings (Suvire and Mercado, 2012;Sutanto and Cheng, 2009;Molina and Mercado, 2003;Karasik et al, 1999;Rojas, 2007). Flywheels can be used together with batteries to reduce the number of discharge cycles of the batteries to extend useful life of the batteries.…”

Distributed generation (DG) in smart grid (SG) is being employed as a means of achieving increased reliability for electrical power systems as regarded by consumers. As the most of DG technologies utilise renewable sources, the power electronic interface plays a vital role to match the characteristics of a DG unit with the grid requirements. This paper presents the power electronics capabilities required for DG systems in SG to convert the generated power into useful power that can be directly interconnected with the utility grid and/or that can be used for consumer applications. Because of the enhancement and the different power ranges of power electronics devices, the development of advanced power electronic interface that is scalable to meet different power requirements, with modular design, lower cost, and improved reliability, will improve the overall performance and durability of smart grid distributed power systems.
