Title: Assessment of Onshore Wind Energy Potential in Fujian Province Based on GIS
Abstract: Scientific and accurate assessment of the regional wind energy potential and its spatial distribution play an important role in the regional energy planning.This study attempts to establish simple and effective methods for assessing regional wind energy resources with GIS software.With daily meteorological data from 23 weather stations in Fujian Province within 30 years,the annual average wind speed with spatial resolution of 1km in the study area has been calculated by using the hybrid interpolation method integrated by trend surface analysis and ordinary Kring interpolation.Based on this data set,we have evaluated the technical potential of wind energy development and generation costs at places 50m,80m and 100m respectively above ground by taking into consideration some geographical restriction factors in the study area such as DEM and land use.The results show that the annual average wind speed has strong correlation with local latitude,elevation and slope.The eastern coastal areas of Fujian province have the best wind energy,which reduces gradually from the east to the west and from the south to the north.The annual average wind speed increases with heights,and it ranges from 0.81 to 7.05m/s at places 10m above ground.The suitable areas for development of wind energy in Fujian are more than 10,000 km2(accounting for about 10%of the total area in Fujian province),mainly located in the eastern coastal regions.Three kinds of main current wind turbines have been chosen as reference equipments for estimation of the technical potential of wind energy.The results indicate that Fujian's total installed capacity of onshore wind power can reach up to 187~245GW,and the average annual power generation can be four to five times as the total electricity consumption of Fujian Province in 2010.At last,the unit costs of wind power generation have been calculated based on the current market situation of wind power,which range from 0.013 to 0.076 Yuan/kWh.The lower costs of wind power are,the better the wind energy is.Therefore,wind power is a significant economic advantage for coastal areas.
