Effect of Low-Voltage-Ride-Through Technologies on the First Taiwan Offshore Wind Farm Planning

Penghu, Taiwan, has the potential to be one of the most valuable sources of wind energy in the world. A 59-km submarine cable that connects Taiwan to Penghu Island is currently in the planning phase, and a large-scale offshore wind farm around Penghu will be developed. This will be the first offshore wind farm to be planned in Taiwan and will have a significant role in the development of renewable energy in this country. In the initial planning phase, various transient impact analyses must be performed. Low-voltage-ride-through (LVRT) capability is one of the most critical items to be analyzed. The main target of this paper is to investigate the effect of LVRT technologies on the first Taiwan offshore wind farm planning. It begins by investigating the development of LVRT technologies, and then discusses the effect of grid strength on the preferred LVRT installation. The critical range of faults that can disconnect the wind farm from the grid with and without LVRT has been studied. Finally, the effect of LVRT characteristics on the transient stability of the power system in Taiwan is evaluated and the strategy of replacing the LVRT installations with reactive power compensation elements is proposed.
