Potential of Offshore Wind Energy and Extreme Wind Speed Forecasting on the West Coast of Taiwan

Abstract

It is of great importance and urgency for Taiwan to develop offshore wind power. However, relevant data on offshore wind energy resources are limited. This study imported wind speeds measured by a tidal station and a buoy into the software WAsP to estimate the high-altitude wind speeds in the two areas. A light detection and ranging (Lidar) system was set up near the tidal station and buoy. High-altitude wind speeds measured by the Lidar system were compared with the WAsP-estimated values, and it was discovered that the two data sets were consistent. Then, long-term wind speed data observed by buoys and tidal stations at various locations were imported into WAsP to forecast wind speeds at heights of 55-200 m on the west coast of Taiwan. The software WAsP Engineering was used to analyze the extreme wind speeds in the same areas. The results show that wind speeds at 100 m are approximately 9.32-11.24 m/s, which means that the coastal areas of west Taiwan are rich in wind energy resources. When a long-term 10-min average wind speed is used, the extreme wind speed on the west coast is estimated to be between 36.4 and 55.3 m/s.

The (R)evolution of China: Offshore Wind Diffusion

“…In general, Taiwan is very open to foreign direct investment and knowledge sharing. Efforts have been rendered within academia to assist the Taiwanese government to map out the potential for offshore wind electricity generation in Taiwan and to analyze the extreme wind speeds experienced on the West Coast of Taiwan [64]. Also, academia has provided useful answers regarding alternative types of foundations for deeper waters such as modified jacket foundations suitable for local conditions and seabed structures in Taiwan [65].…”

Unsynchronized Phasor-Based Protection Method for Single Line-to-Ground Faults in an Ungrounded Offshore Wind Farm with Fully-Rated Converters-Based Wind Turbines

“…At 7 s, the wind speed reached 12 m/s and was kept constant, which is the rated wind speed for the FRC-WT with PMSG. The active power output of the offshore wind farm also ramped up to the maximum power level [33][34][35][36][37]. An SLG fault between the cable, the sheath, and the ground was simulated on the 33-kV collector feeder 1, with a fault impedance of 0.01 Ω.…”

Modeling of Load Bearing Characteristics of Jacket Foundation Piles for Offshore Wind Turbines in Taiwan

“…Among renewable energy technologies, offshore wind is regarded as one of the most attractive renewables to be developed. According to the wind speed data measured by a tidal station and a buoy on the west coast of Taiwan, the wind speeds at a height of 100 m are approximately 9.32 to 11.24 m/s [1]. It was found that the coastal areas west of Taiwan are rich in wind energy resources.…”
