Study the Harmonics of LED Lamps in the Domestic Electrical System

This study investigates the harmonic distortion introduced by LED lamps within a steady-state condition in residential electrical systems and its implications for power quality and system reliability. Lighting, accounting for approximately 20% of global electricity consumption, has significantly transitioned to solid-state technologies like LEDs, known for their energy efficiency and long life. However, the inherent non-linear behavior of LED drivers results in substantial harmonic distortions that can adversely affect power system infrastructure and connected devices. Harmonic patterns were analyzed across various locations using a simulated medium-sized residential model with 26 sockets. Results indicate a significant harmonic pattern at different sockets of the non-linear load. The results of this research highlight the importance of considering the impact of harmonics in the management of residential electrical systems.
