Harmonic measurement and modeling for mass implementation of nonlinear appliances

In order to analyze the effects of a widespread use of nonlinear appliances harmonic measurements are done on specific examples like compact fluorescent lamps (CFL) and photovoltaic (PV) inverters. The results of the investigation determine requirements on nonlinear models, which are necessary to consider the impact of mass implementation. Particularly, the voltage and operating point dependency of the harmonic currents are taken into account. Furthermore, this paper provides an overview of existing nonlinear models and emphasizes their advantages and disadvantages. Thereby, the main focus is on models, which uses a measurement based approach.
