Abstract

The paper shows a method of simulation of the stationary and dynamic behaviour of the grid connection of a large number (100…300 and more) of parallel-connected modular inverters which are used in solar facades. Furthermore, it describes the models and their parameters and the results of many simulations by modifying these parameters. It shows the properties of the simulation system used and the significant simulation results (for any number of modular inverters): the time behaviour (transients) of the mains current and the mains voltage; the harmonic spectra by online FFT; and the dependence of the harmonic content on the tolerance range
