Abstract
Due to grid code requirement, stability analysis, and design of controller for renewable energy connection to the grid, it is mandatory to analyze the dynamic behavior of renewable energy power plants. The first step for this analysis is the extraction of the dynamic model of the power electronics interface, which is the object of this chapter. In recent years, to characterize the small-signal dynamics higher than half the switching frequency in power converters, linearization modeling approaches have been continuously improved. The present study reviews the small-signal modeling techniques and compares them based on voltage-mode controlled buck converters. This study uses the harmonic state-space modeling, describing function method, and small-signal average modeling to enable better selection of a proper method to model and analyze power electronic circuits and power systems based on power electronics. However, these models cannot explain the frequency coupling interactions, such as beat frequency oscillation, of several converters. Thus, for this purpose, multi-input multi-output-based harmonic state-space models have to be used.
