Currently there is a high interest in offshore grids, especially can be mentioned the matter of increasing power generation from offshore wind farms, supplying offshore loads and cross-border connections. In this article typical elements incorporated within offshore grids will be mentioned: wind farms, high power loads, gas turbines and marine current farms. The aim of this article is to comment on means of modelling methods for angle stability analysis within offshore grids. Furthermore, this article dissertates about exemplary results of stability analysis of offshore grid test model.
