摘　　要：英国的能源白皮书建议,到2020年将可再生能源的比例增加到20%。提高可再生能源的比例,必然会增加一些额外成本。文章假设所有可再生能源电力来自风能,识别和计算对于消费者的额外成本,这样就可以对风能的间歇性影响进行研究。额外成本包括增加的发电成本、额外平衡成本和加强输配电系统的成本,对其假设的基础进行了明确说明。比较了2种假设情况下的总成本,一种假设是20%电力来自风能,另一种假设是总发电量全部来自天然气发电。结论说明,风电在电力供应中占较大的比例,没有任何技术上的障碍。The recent UK Energy White Paper suggested that the Government should aim to secure 20% of electricity from renewable sources by 2020. A number of estimates of the extra cost of such a commitment have been made, but these have not necessarily included all the relevant cost components. The analysis in the artical sets out to identify these and to calculate the extra cost to the electricity consumer, assuming all the renewable electricity is sourced from wind energy. This enables one of the more controversial issues-the implications of wind intermittency-to be addressed. The basis of the assumptions associated with generating costs, extra balancing costs and distribution and transmission system reinforcement costs are all clearly identified and the total costs of a ＂20% wind＂ scenario are compared with a scenario where a similar amount of energy is generated by gas-fired plant. This enables the extra costs of the renewables scenario to be determined. It is concluded that there does not appear to be any technical reason why a substantial proportion of the country＇ s electricity requirements could not be delivered by wind.
