Deregulation has emphasized the necessity for new schemes, which are capable of tracking and mitigating voltage disturbances due to non-linear loads. This paper introduces a new approach to track the voltage flicker levels in distribution systems, which is produced by large non-linear loads like arc furnaces. The new tactic depends on an innovative technique for voltage disturbance tracking, which utilizes the Teager Energy Operator TEO. This paper discloses that TEO is capable of tracking the amplitude variations of the flicker voltage in industrial systems. Results are presented to validate and verify the tracking capability of TEO and to indicate superior performance of TEO to track voltage flicker.
