Virtual inertial control can be implemented on wind turbines and energy storage systems [14], [15]. Time-varying load and PV are also applied in virtual inertia control to mitigate the power ramp rate [16]. Usually supercapacitors work together with battery energy storage systems (BESS) to achieve better performance [17].

To solve the parallel circulating current problem in the operation control of modular energy storage converter, the causes of the parallel circulating current are

Based on the working condition in the article, the simulation results indicate that the proposed control strategy can decrease the maximum circulation current between the multiple inverter from 30

When two inverters with different capacities are operated in parallel, the difference in line impedance of each inverter will inevitably lead to a circulating current between the systems [].The size of the circulating current is related to the output voltage and the impedance of each inverter, and the difference between the output voltage of each
