中文摘要:
      分别选取风电和传统煤电典型项目,使用LCOE方法比较新能源与传统能源项目的长期投资平均成本,结果表明,即使不考虑新能源发电的鼓励性政策补贴和传统能源发电的环境外部性,风电项目仍比火电项目具有明显的成本优势,否定了对新能源成本过高的固有认识。阻碍我国可再生能源如风电发展的根本因素不是发电成本,而是来自电网消纳和输送能力的制约,目前我国风能资源丰富地区大部分用电负荷较小,大规模风力发电面临当地电网难以消纳的问题。因此,应加大对智能电网建设的投入,加强风电配套设施建设与维护,并在有条件的电力需求中心附近发展风电。
英文摘要:
      This paper uses LCOE method to compare the average cost of long-term investment between renewable energy projects and traditional energy projects by choosing wind power and typical projects of traditional coal-electric power respectively,and the results show that wind power projects have obvious cost advantage over coal-electric power projects even though encouraging policy subsidy of renewable energy and environmental externality of traditional coal-electric power are not considered,which denies the cognition that renewable energy has too much cost,that the basic factor hampering renewable energy such as wind power is not power cost but is the restriction from the processing capacity and transmission capacity of power grid, and that in the areas of China with rich wind power,currently,majority of the areas have small power load capacity and large-scale wind power faces the difficulty in the process capacity of local power grid. Thus,China should enlarge the investment in intelligent power grid construction,strengthen the construction and maintaining of matched facilities for wind power and develop wind power around the places with the power demand centers.
