This paper investigates the integration of Superconducting Magnetic Energy Storage (SMES) System into the standalone Permanent Magnet Synchronous Generator (PMSG) based on Variable Speed Wind turbine (VSWT) in DC Microgrid system. The primary aim of SMES system is to retain power balance by drawing power during high wind generation and to extricate it during low power generation. An effective c...

A unified approach is suggested for the derivation of current-tocurrent converter topologies, which relies on duality principles. As conventional duality rules have restricted utility and are difficult to apply with switched mode circuits, special attention is devoted to switch mode converter element dualities. Also, a special means of viewing complex switched mode topologies as a cascade combi...

A transient stability analysis is done for a multi-area power system with Static Synchronous Series Compensator (SSSC) integrated with Superconducting Magnetic Energy Storage (SMES) system. The SSSC is realized with Voltage Source Inverters (VSI) and the SMES is realized as a coil. The real and reactive power reference values are set constant and a three phase fault is created in one of the tra...

The design of a twin coil 2 × 200 kJ–1 MW pulse power high temperature superconductor (HTS) superconducting magnetic energy storage (SMES) demonstrator is presented. Its aim is to test at small scale various possibilities of electromagnetic launcher powering. The foreseen operation modes include high voltage discharge in power capacitors, sequential discharges of identical energies from two cou...

Wind power causes fluctuations in power systems and introduces issues concerning system stability and power quality because of the lack of controllability of its discontinuous and intermittent resources. This paper presents a coordinated control strategy for solid oxide fuel cells (SOFCs) and superconducting magnetic energy storage (SMES) to match the intermittent wind power generation and comp...

We use inelastic neutron scattering to study magnetic excitations of the FeAs-based superconductor BaFe1.9Ni0.1As2 above and below its T_{c} (=20 K). In addition to gradually open a spin gap at the in-plane antiferromagnetic ordering wave vector (1, 0, 0), the effect of superconductivity is to form a three-dimensional resonance with clear dispersion along the c axis. The intensity of the resona...

The theory of fluctuation induced first order phase transition from normal to uniform (Meissner) superconducting state in a zero external magnetic field was developed for thin films of type I superconductors in a series of papers [1, 2, 3, 4, 5, 6, 7]. The same problem was considered in a recent theoretical investigation [8]. The authors of the paper [8] derived an erroneous effective free ener...
