BATTERY ENERGY STORAGE SYSTEM Russian patent published in 2023 - IPC H02J3/32 

Abstract RU 2793398 C2

FIELD: electrical engineering.

SUBSTANCE: battery storage system used to provide balancing services for the power distribution network is designed to monitor the state of charge (SoC) of the battery (26). If the SoC is within the optimal range (48), the balancing service is provided by solely charging or discharging the battery. If the battery SoC falls below a predetermined lower threshold (52), the first non-battery asset is put into service to increase the amount of electricity supplied to the grid. Likewise, if the battery SoC rises above a predetermined upper threshold (50), the second non-battery asset is brought into use to provide a balancing service. In order for the system to meet balancing service regulatory requirements, the battery only needs to retain the ability to charge or discharge beyond each threshold (50, 52) for a period of time that covers the time required for the respective asset to reach operating capacity.

EFFECT: reduction of requirements for energy storage capacity of the battery.
