Energy storage power stations use batteries and other energy storage media to store energy during the low load period of the power grid and release energy during the peak period to stabilize the power grid. Since the power grid has strict requirements on the stability of frequency and voltage, energy storage power stations must be able to respond quickly to the regulation needs of the power grid. The monitoring system needs to obtain the operating data of the energy storage power station in real time to quickly respond to changes in the power grid.

[0003] The energy storage power station system needs to accurately predict the failure probability of the UPS to reduce false alarms and missed alarms; at the same time, it needs to execute complex control strategies based on the real-time needs of the power grid and the status of the UPS. When the power grid fails or is under maintenance, the energy storage power station needs to provide stable power support. Through real-time monitoring and prediction, system failures can be reduced and the reliability of the energy storage power station can be improved; through effective energy conversion and circulation, the needs of the power grid can be met and energy utilization efficiency can be improved. In the event of a power grid failure, the energy storage power station can provide emergency backup power to ensure continuous power supply to critical loads. In addition, the energy storage power station can quickly respond to the regulation needs of the power grid, such as frequency regulation, peak reduction, etc. To this end, we propose a safety protection system for energy storage power stations.
