A Generic Model for Power Park Modules for Both Transient and Small-signal Stability Analysis

Power Park Modules (PPM), such as wind and photovoltaic plants, bring new modelling challenges and they are usually aggregated into equivalent or generic models for stability analysis. However, most of the existing approaches to build these models are suited only for the transient stability and, generally, for a specific kind of PPM like wind farms. Moreover, some of them might not be always appropriate in the case of large-scale systems since they require significant computational effort. In this paper, a new methodology is proposed to construct generic models for PPM based on transfer matrices. It is suited for both transient and small-signal stability analysis, independently on the kind of the PPM and its technology. It has also low computational requirements. Its validation is done in Matlab and Eurostag software’s by considering a realistic power system of 23 generators to which a wind farm is connected.
