Integration of CFA ² FB control scheme with modified shunt active line conditioner ( MSALC ) connected distribution system for mitigation of harmonics

Abstract

Objective: The main objective of the proposed control scheme is the elimination of harmonics present in the output with minimum injection. Methods: The proposed hybrid control scheme is the fusion of both the Cuttlefish Algorithm (CFA) and Artificial Feeding Birds (AFB). Results: The proposed method is implemented in Matlab Simulink working platform. The results are carried out with different case studies and the performances of proposed technique are compared with various existing techniques. In this dissertation, the obtained harmonic current ratio factor (HCRF) for the proposed technique is 7.3432%. Conclusions: The results are carried out with different case studies and the performances of proposed technique are compared with various existing techniques. From the result outcomes, it is proved that the proposed technique stands to be remarkable with high accuracy, high response, and minimum total harmonic distortion (THD) for source and load current. It responds excellently under all the load conditions.
