TY  - JOUR
AB  - Large offshore wind farms are usually composed ofseveral hundred individual wind turbines, each turbine havingits own complex set of dynamics. The analysis of the dynamicinteraction between wind turbine generators (WTG), interconnectingac cables, and voltage source converter (VSC) based HighVoltage DC (HVDC) system is difficult because of the complexityand the scale of the entire system. The detailed modelling andmodal analysis of a representative wind farm system reveal thepresence of several critical resonant modes within the system.Several of these modes have frequencies close to harmonicsof the power system frequency with poor damping. From acomputational perspective the aggregation of the physical modelis necessary in order to reduce the degree of complexity to apractical level. This paper focuses on the present practices ofthe aggregation of the WTGs and the collection system, andtheir influence on the damping and frequency characteristics ofthe critical oscillatory modes. The effect of aggregation on thecritical modes are discussed using modal analysis and dynamicsimulation. The adequacy of aggregation method is discussed.
