Voltage Flicker Analysis Based on Improved Independent Component Analysis

Abstract

The traditional independent component analysis uses Newton method to optimize its cost function, so it always falls into local optimal solution. This affects its application in voltage flicker detection. To improve the performance of voltage flicker detection based on independent component analysis, this paper uses artificial bee colony algorithm that has global optimization to optimize the cost function of independent component analysis. Simulations prove that the improved voltage flicker detection method has better performance than the original method.
