基于改进物元可拓法的跨国联网工程综合效益评价

Comprehensive benefit evaluation of the transnational power grid interconnection project based on improved matter-element extension model

落实“一带一路”倡议,推动跨境电网互联互通是“十三五”期间中国电力工业发展的重点任务之一。电网互联项目,尤其是跨国联网工程必然成为电网投资的重要方向。为了更全面地评价这类投资的综合效益,以提高投资决策的准确性,文中从经济、社会和环境3个方面构建了针对跨国联网工程的综合效益指标体系。为充分利用主客观信息,采用唯一参照物比较判断法和熵权法相结合的指标权重确定方法,应用灰关联改进物元可拓模型对跨国联网工程进行了综合效益评价。研究成果有助于提高电网公司跨国投资的决策水平,同时为有效保证国家间的平等互利合作奠定了基础。

Implementing"the Belt and Road Initiative"to promote the interconnection of cross border power grid is one of the key points of the development of China′s power industry during the"13th Five-Year"period.The implementation of power grid interconnection projects,especially the transnational power grid interconnection projects,will inevitably become an important direction of investment in power grid.In order to evaluate the comprehensive benefits of such investments more fully and improve the accuracy of investment decisions,the comprehensive benefit evaluation index system of such projects is constructed from three aspects:economic,social and environmental benefits.In order to make full use of the subjective and objective information,the combination method of the only reference object comparison judgement and entropy weighting method is used to determine the index weight.At the same time,matter-element extension model improved by gray correlation is used to evaluate the comprehensive benefit of such projects.The research will help improving power grid corp′s decision-making level on transnational investment and lay the foundation for effectively guaranteeing equality and mutually beneficial cooperation among countries.
