The application relates to the technical field of
energy storage, and discloses a
hybrid energy storage system and method supporting
mode switching, which comprises a
data acquisition and communication module, an operation state analysis and mode decision module, a switching
trajectory planning and cooperative control module, a
safety monitoring and dynamic compensation module, a panoramic instruction integration and execution module, and a strategy self-learning and optimization module; target
operation mode instructions are generated by inputting comprehensive operation state characteristic data of the
system into a pre-trained mode research and judgment neural
network model, combining a pre-set
hysteresis comparison strategy and a
minimum time interval constraint of
mode switching, and realizing research and judgment on multiple operation
modes such as power
smoothing, peak clipping and valley filling,
frequency modulation auxiliary services, so that frequent
mode switching caused by state fluctuations is avoided; characteristic data, control sequences and safety
evaluation data of the whole switching process are recorded to form a history
library, and the optimization of the switching strategy is realized.
