“…Focusing on multi-area power systems with an increase of RESs penetration, applications of interconnected power systems are widely increased to exchange power and strengthen stability and reliability. In [15][16][17][18], superconducting magnetic energy storage (SMES) systems and HVAC/HVDC parallel tie-lines have been designed and studied for a different type of interconnected power systems. Based on the aforementioned references, there is no report for inertia control methods to analyze the effects of inertia during high RESs penetration and contingencies.…”

Due to a rapid increase in the utilization of power converter-based renewable energy sources (RESs), the overall system inertia in an interconnected power system might be significantly reduced, increasing the vulnerability of the interconnected power system to the system instability. To overcome problems caused by the significant reduction in system inertia, this paper proposes a new application of virtual inertia control to improve frequency stability of the interconnected power system due to high penetration level of RESs. The derivative control technique is introduced for higher-level applications of virtual inertia emulation. Thus, the proposed virtual inertia control loop has a second-order characteristic, which provides a simultaneous enabling of damping and inertia emulations into the interconnected power system, enhancing frequency stability and resiliency. System modeling and simulation results are carried out using MATLAB/Simulink ® (R2016b, MathWorks, Natick, MA, USA). Trajectory sensitivities are also performed to analyze the dynamic effects of virtual inertia control's parameters on the system stability. The effectiveness of the virtual inertia control concept on stability improvement is verified through a multi-area test system with high RESs penetration level for different contingencies.

“…However, these RESs power potential repeatedly changes and are barely predictable due to change in the environmental conditions. This can lead to undecorated complications due to severe fluctuations of tie-line power flow [4]. To overcome this problem, superconducting magnetic energy storage (SMES) can be utilized as an effective device with the ability to possess high storage efficiency, rapid response (within few milliseconds) and high cyclability, but only for short periods of time [5].…”

Abstract-One of the most promising applications in High Temperature superconductor (HTS) is SuperconductingMagnetic Energy Storage (SMES). At present, electrical storage systems reports 50-60% losses due to traditional use of conventional conductors. In order to overcome such challenges, HTS with efficient cooling must be employed in power applications. In the present work, a novel cooling concept with supercritical oxygen (SCO) has been proposed to maintain the superconducting state for wide range of applications. Moreover, the thermophysical properties such as viscosity, density, thermal conductivity and specific heat have been studied over a wide range of temperatures (154.58K-204.58K) and critical pressure 50.43bar. Further, the development of correlations for SCO above the critical temperature (T c +50K), and at critical pressure (P c +1bar) have been analyzed. The developed correlations can be used in predicting the performance of SMES power devices by prior modeling and simulations at various operating conditions. Index Terms-Correlation, SMES, supercritical oxygen, and thermophysical properties.
