The technology of virtual inertia control considering the state of charge of hybrid energy storage

Year: 2024

Type: conference-paper

Abstract: There is an increasing amount of new energy power generation being applied in power systems. However, the new energy units have a weak inertia response capability. PV power and large-scale wind energy are linked to the grid, causing the power system’s inertia level to drop noticeably, which has a negative impact on the power system’s frequency stability. Based on this, this paper introduces the Hybrid Energy Storage System (HESS) made up of batteries and supercapacitors, beginning with the concept of power system inertia. The synchronous generator’s rotational kinetic energy is then coupled with the static energy stored in the energy storage device to give it a virtual rotational moment of inertia. Lastly, an analysis is conducted on the HESS’s virtual inertia control technology. Additionally, a sample analysis is performed. The virtual inertia of the HESS is suitably regulated to provide inertia support for the system based on the energy storage device’s state of charge.
