Predict the level of harmonic distortion due to dispersed generation

A simple though accurate method is developed to estimate the pollution of the electricity network with harmonics in case a large number of inverters is presented. The method is called the ´Complex Conductance Measurement Method´. Although this method is written for inverters of small grid connected micro generators, it can also be applied for all kinds of loads. A measuring method to determine the necessary frequency dependent parameters of inverters and loads in general is presented.
