renewable energy sources (res), especially wind power plants, have high priority of promotion in the energy policies worldwide. an increasing share of res and distributed generation (dg), should, as has been assumed, provide improvement in reliability of electricity delivery to the customers. paper presented here concentrates on electricity storage systems technologies and applications pinpoint...

We consider a mesoscopic mechanism of the exchange interaction in a system of alternating ferromagnetic/nonmagnetic metallic layers. In the case of small mesoscopic samples the sign and the amplitude of the the exchange interaction energy turn out to be random sample-specific quantities. They can be changed by applying an external magnetic field, by attaching to the system superconducting elect...

Received DOI: 2 Superconductivity arises when solids have conducting bands (singly occupied wave functions) that do not have electron-nuclear scattering (Fermi contact) and the temperature is low enough to eliminate partial wave scattering of electrons. This means that the conducting bands do not include s basis functions (atomic quantum numbers l ,m = 0), and the temperature is low enough so t...

A nonconventional technique for the measurement of magnetic relaxation in superconducting films at short times (;10 s) is described. This technique combines the application of a pulsed magnetic field and a synchronized high-energy pulsed laser. Remanent magnetic relaxation in ~Y;Gd!Ba2Cu3O72d thin films is reported over five decades time at reduced temperatures above 0.8. © 1998 American Instit...

THE Energy Buncher at the low energy beamline of the superconducting fragment separator (Super-FRS) (Figure 1) at FAIR is a valuable and attractive experimental device for particle identification after secondary reactions. This device will be at the heart of the experimental facility for nuclear and reaction (NuSTAR) studies using radioactive ion beams at FAIR. The dipole, quadrupole and sextup...

Superconducting multipole wigglers installed on synchrotron radiation sources are the powerful tools for researches in various areas of science and technics. SuperConducting Multipole Wigglers (SCMWs) represent sign-alternating sequence of magnets with lateral magnetic field. Relativistic electrons, passing through such set of magnetic elements, create radiation with properties of synchrotron r...

We present a study of Josephson junctions arrays with two-band superconducting elements in the highcapacitance limit. We consider two particular geometries for these arrays: a single rhombus and a rhombi chain with two-band superconducting elements at the spinal positions. We show that the rhombus shaped JJ circuit and the rhombi chain can be mapped onto a triangular JJ circuit and a JJ two-leg...

In this study, a fuzzy gain scheduled proportional and integral (FGPI) controller was developed to regulate the power flow regulation of Static Synchronous Series Compensator (SSSC) in a multi-area power system. Also, this FGPI was developed for the SSSC without and with Superconducting Magnetic Energy Storage (SMES) system. Two performance criteria were utulized for the comparison. First, sett...
