Embodiment Construction
[0045] Attached below Figure 1~8 The present invention is further described with embodiment:
[0046] The structure principle of the microgrid control system is as follows: Figure 4 As shown, the storage battery, supercapacitor and photovoltaic battery module are connected to the grid bus through AC / DC, and the load is directly connected to the grid bus. The control system uses data collection to obtain the following: Figure 2~3 The input voltage value U and current value I are output by the control system to control AC / DC corresponding to the storage battery, supercapacitor and photovoltaic cell assembly, and the output of the control system also controls the change of the load.
[0047] Depend on Figure 1~8 As can be seen from the shown embodiment, the main steps of this embodiment are as follows:
[0048] Step 1: According to Figure 6~8 Prediction of photovoltaic output power of medium photovoltaic cell modules and load power prediction , to calculate the diffe...
