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
