中国海上风光波浪能互补性评估研究

On the basis of evaluating the potential of offshore wind，solar and wave energy resources in China，the complementarity assessing index for multiple renewable energy resources are defined and applied to assess the complementarity of wind，solar and wave energy resources. Meanwhile，the installed capacity ratios are optimized to obtain the optimum complementarity effects. Analysis results reveal that the wind，solar，and wave energy resources are abundant over sea areas in China and show complementarity potential. In most areas of Bohai Sea，Yellow Sea and South China Sea，the complementarity of wind-solar-wave hybrid energy system is larger than the complementarity between two renewable energy resources. Compared with wind-solar，wind-wave，and solar-wave hybrid energy system，the synthetic fluctuation index of power output of wind-solar-wave hybrid energy system is reduced by 86.0%，38.5%，and 10.4%，respectively.
