This paper proposes the new hybrid energy storage system with the superconducting magnetic energy storage (SMES) and a lead-acid battery. The SMES is the most effective energy storage device due to its high power density, fast response, and high efficiency. However, its energy density is not higher than that of other batteries. Therefore, the proposed hybrid energy storage system combines these two energy storage devices. The optimal sizes of the SMES and battery are determined by considering the system cost, output power reference, and their proper efficiencies. Also, the new control algorithm is applied to share the charging and discharging powers effectively and therefore to manage the state-ofcharge (SOC) in each energy storage device. Then, the performance of proposed hybrid energy storage system is evaluated on a residential photovoltaic (PV) system with respect to energy capacity, peak load leveling, and system efficiency.

Abstract-Virtual inertia is known as an inevitable part of the modern power systems with high penetration of renewable energy. Recent trend of research is oriented in different methods of emulating the inertia to increase the sustainability of the system. In the case of dynamic performance of power systems especially in automatic generation control (AGC) issue, there are concerns considering the matter of virtual inertia. This paper proposes an approach for analyzing the dynamic effects of virtual inertia in two-area AC/DC interconnected AGC power systems. Derivative control technique is used for higher level control application of inertia emulation. This method of inertia emulation is developed for two-area AGC system which is connected by parallel AC/DC transmission systems. Based on the proposed technique, the dynamic effect of inertia emulated by storage devices for frequency and active power control are evaluated. The effects of frequency measurement delay and PLL effect on are also considered by introducing a second-order function. Simulations performed by Matlab software demonstrate how virtual inertia emulation can effectively improve the performance of the power system. A detailed eigenvalue analysis is also performed to support the positive effects of proposed method.

“…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.
