6 FAQs about [Energy storage power station voltage drops]
What is the entropy value of energy storage power station?
For the energy storage power station in Hunan Province sampled in the paper, the entropy value Hq of discharged quantity is stable at 0.6931, and the entropy value HΔu of the sharp voltage drop amplitude is stable in the range of 1.2–1.4, consisting with ΔSOC statistical analysis of cells in the cluster;
What is the voltage range of energy storage power station?
The range of abnormal voltage is from 0 to 3.39 V, and the temperature range is from 22 to 28 °C. The current jump is caused by the switching between charging and discharging of the energy storage power station. The SOC ranges from 17.5 to 86.6%.
Does energy storage power station's characteristic data change over time?
Changes of the average value of the characteristic data for the energy storage power station in several days From Fig. 14, it can be seen that the average value of discharged quantity and the average value of sharp voltage drop have little change, which can simply reflect the aging degree of battery clusters in the energy storage power station.
Can a battery energy storage station be used for power compensation?
The output power of conventional thermal power units has a hysteresis. Hence, the power of the battery energy storage station can be used for power compensation in the initial stage of system power shortage.
What is a large-scale energy storage power station?
The large-scale energy storage power station is composed of thousands of single batteries in series and parallel, and the power distribution of each battery pack is the key to the coordinated control of the entire station.
Why do energy storage power stations need a lot of data collection objects?
The data collection objects always focus on the physical attribute data of batteries, but in a large-scale energy storage power stations, too much attribute data will cause data redundancy and need a lot of storage space, causing the probability of date pollution.
