The greatest energy potential was found in the offshore area of Phu Quy island (Binh Thuan province). The area, alone, can provide the 38.2 GW power generation capacity corresponding to the increasing renewable-energy demand by 2030 planned by the country. There is also a drawback of the wind resource, which is associated with strong multiple-scale temporal variabilities. The seasonal variability associated with monsoon onsets and daily variability associated with the wind diurnal cycles were found ranging 30-50%. Meanwhile, the inter-annual variability could reach up to 10%. These variabilities must be considered when designing wind farms and grids over the region. Additionally, due to the fact that the WRF model performed climatological features of the winds well against the observations, this results indicate that it can be useful tools for wind-power assessment as compared to other reanalysis or QuikSCAT data with courser spatio-temporal resolutions.Van Q.DoanDinh Van-NguyenKusaka HiroyukiThanh CongToan Du VanDinh Duc Nguyenducnd@vnu.edu.vn2019-06-03T03:51:35Z2019-06-03T03:51:35Zhttp://eprints.uet.vnu.edu.vn/eprints/id/eprint/3423This item is in the repository with the URL: http://eprints.uet.vnu.edu.vn/eprints/id/eprint/34232019-06-03T03:51:35ZNumerical Approach for Studying Offshore Wind Power Potential Along the Southern Coast of VietnamRecently, offshore wind energy has received much attention in Vietnam; however, the understanding of its potential is insufficient to sparse in situ observations. This study introduce a numerical approach for studying the offshore wind potential in the southern Vietnam. A regional climate model used to simulate wind field is configured so that the inner most domain covers whole the region of interest with the grid spacing of 10 × 10 km. The model is run for 12 months of 2012 to capture the annual variation of wind. The results show the southern Vietnam region is characterized by strong seasonal and spatial variabilities in both wind speed and direction. In particular, the offshore areas of Ninh Thuan and Binh Thuan provinces are likely to have the largest wind power potential as well as the strong seasonal variation. This study demonstrates that the numerical approach can fill the gap of measurements and the results obtained can be used to identify optimal locations for offshore wind farms over the region.Van Q.DoanKusaka HiroyukiToan V.DuDinh Duc Nguyenducnd@vnu.edu.vnCong Thanh2017-02-28T09:07:45Z2017-02-28T09:07:45Zhttp://eprints.uet.vnu.edu.vn/eprints/id/eprint/2448This item is in the repository with the URL: http://eprints.uet.vnu.edu.vn/eprints/id/eprint/24482017-02-28T09:07:45ZApplying dynamic downscaling method with a high-resolution regional climate model for local climate projection in greater Hanoi cityQuang Van DoanKusaka HiroyukiMinh Truong NguyenHong Duc Doandoan.hd.amsl.eng@vnu.edu.vnDinh Duc Nguyenducnd@vnu.edu.vn
