Embodiment Construction
[0050] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0051] The invention adopts batteries and supercapacitors to form a hybrid energy storage system, and judges whether the hybrid energy storage system needs output and determines the respective output power of the two energy storage media according to the power fluctuation degree of the intermittent power supply. At the same time, the SOC (State Of Charge) level of the energy storage system is taken into account to prevent overcharging or overdischarging of the energy storage system, thereby ensuring the safe and stable operation of the energy storage system.
[0052] figure 1 It is a control block diagram of the hybrid energy storage system to stabilize intermittent power fluctuations. Such as figure 1 As shown, the present invention collects the real-time power P of intermittent power supply by the data acquisition mo...
