AB  - Wind power has been the fastest growing energy generation sector worldwide in recent years. Large on- and off-shore wind farms have a considerable impact on system security and stable system operation. Therefore its influence on the dynamic stability of the system must be addressed. For turbines above 1MW, doubly-fed induction generators (DFIG) are the most widely used concept. However in many countries such as U.K and Germany, full-rated converter (FRC) have also gained vast amount of market penetration.To address this, the paper presents studies performed in DIgSILENT PowerFactory aimed at ascertaining the impact that DFIG and FRC have on the oscillation modes of the power system. The feasibility, advantage and disadvantages of various options are discussed.Wind generators can be connected to existing power transmission networks spanning over long distances and ultimately causing interaction between wind-farms and transmission systems. The benefit of utilising HVDC (classical and/or Voltage- source) within an ac network for transporting large amounts of wind power to remote load locations is studied.Wind farms consist of large number of generators of relatively small size. Both types of variable speed wind generators (DFIG and FRC) have been modelled in detail in PowerFactory DIgSILENT. Model aggregation techniques are applied to reduce computation time. Different control strategies for VSC-HVDC and “classical” Thyristor-based HVDC links are presented and analyzed via network simulation. A case study is presented based on the equivalent SE Australian power system, an IEEE benchmark system for dynamic studies, with appropriate reinforcements introduced to accommodate wind generation and HVDC transmission systems.This paper is focused on the small-signal stability issues and analyses the impact of various aspects like generator technology, hybrid AC/HVDC transmission for getting a thorough understanding about the impact of these on the overall system sta
