A novel pilot protection scheme for transmission lines based on current distribution histograms and their Bhattacharyya coefficient

•The current characteristics at both ends of a transmission line are represented by probability distribution histograms.•The similarity of current distribution histograms is quantified by Bhattacharyya coefficient (BC) to form a novel pilot protection scheme.•The proposed scheme is applicable to fau...
