Offshore Wind Energy Assessment Considering Different Wake Effect Models

China has good offshore wind energy potential due to vast coastline. An accurate assessment can help make wind energy projects development decisions, as a result, wind resource assessment in China is challenging but of great use. In this paper, a case of one year (2021) in Shanghai is described using WindSim Evaluation and WindRose PRO3 with focus on annual wind power production and wake effect. WindRose PRO 3 is carried to analyze raw wind park field data such as wind direction, wind speed, atmosphere temperature and pressure and produce correspond pictures. WindSim Evaluation is a professional software which simulates wind turbines work condition and produce wind resource results and annual electricity production under different wake effect models. Both WindSim Evaluation and WindRose PRO 3 are used for assessment of offshore wind energy potentials. In different wind parks, the wake effect has a strong influence on the wind turbines and annual output.
