Observation and Simulation of Wind Energy Resource in Jiangsu Coastal Area

In order to assess the potential of wind energy resource in Jiangsu coastal area, observation and simulation method are used to study the evolution and distribution of wind speed and wind energy of surface layer in this region. The wind speed data in 2005 of Dongling wind tower of Rudong showed that the wind speed increased in accordance with the laws of the natural logarithm with height, the wind speed is maximum in the month of May then in February and is more obvious at the height of 40 m above the ground, and the wind speed is minimum in the months of January, April, July and November. MM5 model is used to simulate the annual wind field in 2006 in Jiangsu province and the simulation results show that, MM5 model can better simulate the wind energy distribution in the entire region. The simulation results compared with the measured results, found that the daily average wind speed of simulation is slightly larger than the actual wind speed. The results also reveal this region has a rich wind energy potential, the annual wind energy is about more than 2300 kwh/m2 at the height of 10 m ~ 60 m, and has guiding significance on the further development of wind power generation in the Jiangsu coastal area.
