Technical Status and Development Trends of Numerical Modeling for Offshore Wind Resource Assessment
Considering the complex and volatile nature of wind energy, numerical models/tools are becoming increasingly important for offshore wind resource assessment. This paper presents an overview on different types of numerical methods/tools used in the offshore wind energy resource assessment. The characteristics and limitations of linear, computational fluid dynamics(CFD), and mesoscale meteorological models have been delineated. The multi-scale modeling framework are attracting more and more attentions in academic and industrial area. Coupling the mesoscale model with a microscale model is proposed to be an efficient method to resolve the limitations of single scale models. The air-sea coupling model has been proved to have better performances in simulating offshore wind, which is expected to be increasingly important for wind resource and ocean environment assessment in the offshore wind farm development. The characteristic of various wake models are thoroughly discussed here. Some challenges existed in an accurate quantification of wake effects are identified in order to guide future research in this area. Overall, further efforts are urgently needed in improving the offshore wind resource assessment.
