Study On Numerical Simulation Of Wind Energy Resource Based On Wrf And Cfd Model

Wind energy is a clean and large amount of storage energy. Wind power which has great development potential is a renewable energy technology, now being more and more attention of the world, and widely developed. In recent years, China has committed to large-scale wind power development that the total installed capacity of wind power has been ranked first in the world. However, due to the insufficient consumptive ability of electrified wire netting, the rapid development of wind power in China is restrict. To this end, National Development and Reform Commission called on the inland areas to carry out the development of distributed wind power actively in2011.The purpose of this study is to explore the numerical simulation method of wind energy for local governments planning the development of distributed wind power.In this paper, the combined model system (WRF/WT) of mesoscale model WRF and Meteodyn WT, a CFD model from France, carrying out the the numerical simulation experiments of region’s wind resources in Hailing Island of Guangdong Province for a horizontal resolution of100mx100m with two numerical simulation program,and compare the results simulated by the combined model system (WRF/WAsP) of mesoscale model WRF and WAsP, a model from Denmark, studying on the applicability of the Numerical Modeling of complex terrain wind, exploring feasibility of its services in the development of wind power.The results showed that WRF/WT model system used in complex terrain wind energy resources numerical simulation assessment is feasible, it can get high-resolution regional wind resource distribution with no observed data or less information of wind tower, also can provide a scientific basis for development of wind power and developing wind farm pre-construction site. The numerical simulation of mesoscale model and CFD model simulated in the regional wind energy resource distribution is more accurate than the simple application of CFD model; the accuracy of regional wind resource parameters’ distribution simulated by WRF/WT is equal to WRF/WAsP; WRF/WT model system is better than WRF/WAsP when the wind speed frequency distribution does not meet the case of weibull distribution and in steep terrain conditions. The mesoscale numerical model’s simulation error is on the key role of the final simulation results, so we need to do further research on the error correction method that using the existing meteorological observation data to correct the mesoscale simulation of wind field near the ground. In addition, the convergence of the mesoscale model and CFD model is the subject of in-depth study...
