“…Wind farms are based either on land or on the shallow sea areas, these are classified as onshore wind farms and offshore wind farms respectively whose comparison is given in Tables 7-9 in various aspects. Better balance of energy is shown by offshore wind turbines when compared to onshore wind turbines prevailing to the wind conditions that persists locally (Wang et al, 2013).…”

In recent years, renewable energy generation, storage, and transmission has been the focus of research. Extraction of power from renewable energy sources is increasing rapidly. Progressively more wind farms are being fastened to the power grid. Large-scale merging of wind farms into electrical power grid presents a few challenges like voltage stability, system operation and control, and power quality due to usage of power electronic converters presenting a major bottleneck. This paper elucidates various types of wind power plant technologies, consequences of power electronic converters and reviews various types of system strength determination methods.

“…Recent experiences in different practical power systems reveal that frequency response is not the only concern due to substantial wind generation. Short-circuit performance also shows a decreasing trend as wind penetration rises [4,5,17,18]. Furthermore, SCR at the PCC of Type-3 and Type-4 WTGs could even drop below 2 in some cases [4], which is much lower than the preferred range of 3 to 5 [19].…”

Power system security concerns due to significant wind generation could be twofold: first, the frequency response and second, the short-circuit performance. Continuous development of wind energy may cause economic replacement and retirement of existing synchronous generators. Modern wind turbine generators (WTGs) do not inherently offer inertia and governor response after a disturbance, which may result in declining frequency response behaviour. Besides, they have limited fault current contribution, which may cause unacceptable short-circuit ratio at the grid connection point of those wind power plants. Traditionally, frequency response and short-circuit performance are individually improved. However, both of them are concurrently affected by high wind penetration. Hence, a common approach to simultaneously enhance both indices is essential. Therefore, this paper introduces an idea of operating some of the retired synchronous generators in the synchronous condenser mode, which is termed as 'post-retirement scheme'. Such a second use of the retired synchronous generators can jointly upgrade frequency response and shortcircuit strength during high wind generation. This study also proposes a methodology to evaluate when and how much post-retirement scheme should be deployed for ensuring an adequate security performance in a wind dominated power system.
