Malkova The development of electric power systems determines the growing probability of low-frequency oscillations, which can be reason of system faults. Traditionally, the task of damping low-frequency oscillations is assigned to synchronous generators, by appropriate setting of the automatic voltage regulator parameters.

Do low-frequency oscillations threaten power system stability?

Low-frequency oscillations (LFOs) are becoming crucial in large interconnected smart grids. They do not threaten power system stability until sufficient positive damping 1. However, Negatively damped LFOs are of concern and should be detected and damped in real time to avoid power system failure 2.

Are battery energy storage systems a power oscillation damping device?

Consequently, ESSs have garnered significant attention for enhancing power system behavior and are considered as power oscillation damping devices in this study. The motivation for the current study is to address low-frequency oscillations by proposing a battery energy storage system (BESS) controller.

Why do base stations have a small backup energy storage time?

Base stations' backup energy storage time is often related to the reliability of power supply between power grids. For areas with high power supply reliability, the backup energy storage time of base stations can be set smaller.

How to determine backup energy storage capacity of base stations?

For the determination of the backup energy storage capacity of base stations in different regions, this paper mainly considers three factors: power supply reliability of the grid node where the base station is located (grid node vulnerability), the load level of the grid node and communication load.

How can a base station save energy?

Energy saving is achieved by adjusting the communication volume of the base station and responding to the needs of the power grid to increase or decrease the charge and discharge of the base station's energy storage. However, the paper's pricing of energy interaction ignores the operating loss costs of the operator's energy storage equipment.

Is backup energy storage time a constant?

In the research, relevant scholars often regard the backup energy storage time of the base station as a constant [22, 23], and only consider the variability of the base station power consumption. Base stations' backup energy storage time is often related to the reliability of power supply between power grids.
