Compact Fluorescent Lamp Modeling for Large-Scale Harmonic Penetration Studies

Low-watt compact fluorescent lamps (CFLs) may account for significant energy consumption of power distribution feeders in future years. This can lead to power-quality concerns because these devices consume highly distorted currents. In order to predict CFL harmonic current emissions into networks, CFL models capable of predicting these emissions accurately are being studied.

On the other hand, these models require great computational effort in large-scale CFL penetration studies. This paper presents and discusses several approximate CFL models based on the harmonic-coupled admittance matrix model which reduces the computational effort while maintaining reasonable accuracy. The performance of the models is validated with CFL laboratory measurements.
