Simulation offshore wind farm in Penghu Island, Taiwan

This study carries out wind energy resource in Penghu Island, Taiwan. Penghu has abundant of wind energy. Wind speed is high in the spring and winter. The most wind energy come from north north east with 40 %. The mean speed and power density at 100 m hub height and roughness length 0 m are 6.82 m/s, and 340 W/m², respectively. Mean speed is proportional with the hub height. However, it is reduced when the roughness length increasing from 0 m to 1.5 m. The offshore wind farm transient impacts on the power system are investigated. The study includes two case impacts analysis: three-phase short circuit current, and wind farm disturbance. The main contribution of this research is pointed out wind energy resource by using WAsP program in the practical location in Penghu Island. ETAP 7.1 program is used to simulation the transient of the wind farm. From the simulation result, it is contribute to the development offshore wind farm in Penghu Island.
