摘要(Abstract)：

十四五规划开发的陆上新能源基地普遍位于远离交流电网的偏远内陆地区。针对远距离、大容量、新能源送出场景，基于层次分析法评估与全寿命周期成本计算，提出了一种规模化新能源外送方案评估及优选方法。首先，建立兼顾技术性和经济性的指标评估体系，明确影响新能源送出方案的指标及内涵；其次，在技术维度层面采用层次分析法构建判断矩阵，计算归一化权重系数，并从运行边界和技术维度权重两方面进行对比分析；在经济维度层面采用全寿命周期成本模型计算全寿命周期内的总成本，同时引入平准化度电成本以简化运行损耗成本的计算；最后，对某新能源外送工程实例，初选三种方案进行计算分析，选择最优输电方案，为大规模新能源远距离外送方案选择提供技术参考。
