Numerical Assessment Of Wind And Wave Energy Resources In The Blue And Yellow Area Of Shandong Peninsula

Shandong province has been developed fast in these few years with its abundant resources and large population. Since the "Development Plan for High-efficiency Ecological Economic Zone of the Yellow River Delta" and the "Development Plan for the Blue Economic Zone in Shandong Peninsula" have been approved by the State Council in 2009 and 2011 respectively, the development of Shandong peninsula is now incorporated into the national development strategy. This place is confronted with new opportunities and challenges that had never appeared in the next period. The overexploitation of fossil energy results in global warming, haze explosion, and a number of environmental problems. Due to the increasingly decrease of the coal and petroleum, the requirement of renewable clean energy become more and more urgent., both the blue and yellow area of Shandong peninsula have a vast ocean area, long coastlines, and abundant ocean energy resources, as well. How to exploit those resources reasonably turns to be an important research task against the background of sustainable development.In this paper, the wind energy and wave energy of blue and yellow areas in Shandong peninsula are selected to evaluate. Necessary information is obtained from the database of the wind field data from 1990 to2011. Averaged wind velocity, significant wind duration, wind power density, wind energy resource grading and total resource reserves of wind energy are used for analysis. A comprehensive evaluation of the wind energy resources in the sea area of Shandong province is carried out. Moreover, daily variation the wind power density and wind velocity history in different seasons is analyzed.SWAN model is employed to simulate and compute the wave condition caused by the wind field change in the west Pacific Ocean. Then it is incorporated into the sea area of Shandong peninsula to calculate the wave height, period, and wave direction, etc. The accuracy and reliability of the simulation is verified by comparing with the measured filed data. After that, wave power density, wave energy resource grading and the total reserves of wave energy are used to evaluate the wave energy resources of Shandong peninsula. Four representative locations Chengshantou (Weihai), Zhaitang island (Qingdao), Penglai harbor(Yantai))are selected to plot wave rose diagrams for different seasons by using the simulation result. They are expected to present wave height frequency from various directions in different season clearly and to provide foundation for engineering design.
