Abstract

Abstract

Numerical simulation of regional wind energy resource requires high performance computing resource. High spatial/temporal resolution models need more running time due to the limit of computing power. So lots of efforts are devoted to improving calculation efficiency of numerical model. The coupled MM5/CALMET model is proved to be suitable for simulating wind energy resource, and it is also recommended by China Meteorological Administration as a numerical simulation model to estimate provincial wind energy resource. Therefore, interpreting the computational flow of MM5 and CALMET models, a multi job management mode is designed based on parallel calculation principle. The numerical simulation of wind energy resource in Zhejiang Province demonstrates that the multi job management mode can significantly improve calculation efficiency of the coupled MM5/CALMET model. In the numerical simulation experiments of monthly parameters which are related to wind energy resource assessment, the CALMET model without parallel calculation needs 1501.2 minutes, but it only costs 149.5 minutes when implementing the multi job management mode, increasing the calculation efficiency of the coupled MM5/CALMET model by 4 times. The multi job management mode shows the ability to further improve the calculation efficiency of the coupled MM5/CALMET model with its simulation area expanding and simulation period prolonging.
