摘　　要：针对地方电网与能源基地直流送端系统并网模式选择问题,构建基于技术、经济和发展规模指标的综合评价指标体系,并考虑主客观因素的影响,提出基于多属性决策的并网模式优选方法。首先,在总结孤岛和联网接入模式存在的问题基础上,建立了一套考虑技术、经济性以及发展规模等多因素影响的综合评价指标体系;其次采用了基于主观权重的层次分析法和基于客观权重的熵权法进行组合权重的选取,提出了基于多属性决策的优选方法,通过计算不同备选方案的相对贴近度,实现并网模式的优选决策;最后,以某实际直流工程为例,验证所提方法的合理性。An evaluation index system based on technology,economy and development scale index is constructed for the grid-connection mode selection of local power grid with DC sending energy base system.Considering the influence of subjective and objective factors,agrid mode optimization method based on multiple attribute decision-making is proposed.First of all,an evaluation index system is established based on the summary of the problems of isolated-connected and gird-connected modes.Furthermore,the analytic hierarchy process based on subjective weight and the entropy weight method based on objective weight are adopted to select the combination weight.And the optimization method based on multiple attribute decision-making is proposed.Bycalculating the relative closeness of different alternatives,the optimal decision of grid-connection mode can be realized.Finally,an actual DC project is taken as an example to verify the rationality of the proposed method.
