Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings.
[0027] A hybrid energy storage system control method based on a fuzzy logic controller of the present invention is used to stabilize the power fluctuations of distributed power sources. The system structure is as follows figure 1 shown.
[0028] A hybrid energy storage system control method based on a fuzzy logic controller of the present invention is characterized in that it includes a low-pass filter, a fuzzy logic controller, a particle swarm optimization algorithm, a supercapacitor SOP, a supercapacitor, and a storage battery. The role of the low-pass filter is to decompose the power fluctuation signal into high-frequency signals and low-frequency signals; the role of the fuzzy logic controller is to obtain the control signal for charging and discharging the supercapacitor through a logical relationship between the input low-frequency signal and the supercapacitor ...
