Having continuous decrease in inertia and being sensitive to load/generation variation are considered crucial challenging problems for modern power grids. The main cause of these is the increased penetration capacities renewables. An unbalanced load with generation largely affects grids’ frequency voltage profiles. Load control (LFC) mechanisms extensively presented solve problems. In literatur...

This paper describes an analytical feasibility study of the use of chemical storage batteries as the power supply for an electric railgun. The railguns studied are capable of accelerating 1 to 10 kg projectiles to 10 km/sec. Batteries were studied because they offer extremely high energy storage density although they operate at low voltage. Thus, an inductive store must be used to provide pulse...

The superconducting gap structure in iron-based high-temperature superconductors (Fe-HTSs) is non-universal. In contrast to other unconventional superconductors, in the Fe-HTSs both d-wave and extended s-wave pairing symmetries are close in energy. Probing the proximity between these very different superconducting states and identifying experimental parameters that can tune them is of central i...

Superconducting magnetic energy storage (SMES) systems are characterized by their high-power density; they integrated into high-energy density systems, such as batteries, to produce hybrid (HESSs), resulting in the increased performance of renewable sources (RESs). Incorporating RESs and HESS a DC bus obtain microgrid concept is considered more attractive option for solving system reliability s...

Wind energy is seen as one of the main pillars renewable energy. However, intermittent nature these sources still poses a major challenge. Moreover, sensitivity to grid faults and response load changes are also concerns. Superconducting devices have been introduced solve storage problems associated with sources. Nevertheless, cost superconducting materials was drawback for their application in ...
