Within the t-t-J model, the physical properties of doped cuprates in the superconducting-state are discussed based on the kinetic energy driven superconducting mechanism. We show that the superconducting-state in cuprate superconductors is controlled by both superconducting gap parameter and single particle coherence, and then quantitatively reproduce some main features found in the experiments...

−− At present, the advance of technology makes possible to include new energy storage devices in the electric power system. In addition, with the aid of power electronics devices, it is possible to independently exchange active and reactive power with the utility grid. This allows to perform a more effective primary frequency control and also to reduce the reserve power of generators. In this a...

The use of Flexible AC Transmission System (FACTS) devices in a power system can potentially overcome limitations of the present mechanically controlled transmission system. Also, the advance of technology makes possible to include new energy storage devices in the electrical power system. The integration of Superconducting Magnetic Energy Storage (SMES) into Static Synchronous Compensator (STA...
