Technical FAQs 4

What is VSG control for PV systems without energy storage?

The VSG control for PV systems without energy storage was designed in Zheng et al. (2017) so that PV systems without storage can also simulate synchronous generator characteristics. Energy storage and PV systems were combined in He (2015) to make the PV system inertial and damped by VSG control.

Can a VSG control technology be used in a PV-Hess inverter?

Conclusion In this paper, a VSG control technology is introduced into the inverter of PV-HESS. An algorithm for power distribution is constructed for HESS, which includes lithium-ion battery energy storage, vanadium redox flow battery energy storage, and CAES.

Can adaptive VSG control improve the performance of energy storage systems?

The results show that the adaptive VSG control method proposed in this paper can actively adjust the magnitude of the virtual inertia in real time based on the frequency changes, thus improving the stable operation performance of the system and increasing the service life of the converters, energy storage units, and other equipment.

Does VSG control affect the frequency stability of energy storage devices?

It is stated in Deng et al. (2018) that the use of VSG control allows the energy storage device to participate in the primary frequency regulation process of the system, but when the frequency deviation is very large, the sag control leads to a decrease in the frequency stability of the system.
