Fast local regulation of off-grid microgrid based on voltage flicker signal detection algorithm

Conventional off-grid microgrid local fast regulation method is based on voltage signal regulation, which does not take into account the operating characteristics of the microgrid and cannot meet the microgrid regulation requirements. Therefore, an off-grid microgrid local fast regulation method based on a voltage flicker signal detection algorithm is designed. The voltage flicker signal of an off-grid microgrid is extracted, and the fluctuation amplitude, frequency, flicker value, and other characteristic parameters of the voltage flicker signal are obtained. Based on the voltage flicker signal detection algorithm, the microgrid local fast regulation command is constructed, which receives the regulation command from the local control system of the microgrid in real time and realizes more accurate microgrid regulation. Comparison experiments are conducted to verify that this method has a better regulation effect and can be applied in real life.
