Flicker Source Location and Responsibility Division Method Considering Flicker Power Fluctuation Characteristics

Le résumé fourni par la source

Aiming at the voltage fluctuation and flicker problem caused by renewable energy mass access, a flicker detection and flicker responsibility division method based on the flicker power are proposed in this paper. This method first uses probabilistic neural networks (PNN) and Hilbert-Huang transform (HHT) to get the characteristic information of fluctuation components in power system monitoring data, calculates the power of flicker to locate the flicker, and then proposes the flicker responsibility contribution degree. In addition, the dynamic time-scale calculation method is proposed to reduce the amount of calculation. Finally, the performance of the presented method is validated through Simulink simulation examples.
