Whether the energy storage power station is included in the prediction system

How to determine the health state of energy storage power station?

Among a great number of attribute data, the discharge quantity q of the cluster and the sharp voltage drop amplitude Δ uohm of the cluster and cells in it are extracted, and the orderliness of these characteristic data is analyzed by the information entropy to realize the effective estimation of the health state of the energy storage power station;

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.

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.

How is the working state of the energy storage power station calculated?

The working state of the energy storage power station is directly estimated by the average value of the characteristic data. Changes of the average value of the characteristic data for the energy storage power station in several days

How BP neural network can predict energy storage power station health state?

The information entropy value predicted by BP neural network can handle the change trend of the orderliness of the characteristic data to achieve the short-term prediction of the energy storage power station’s health state.
