Abstract /摘要：

MT：为消除我国输电瓶颈,提高可再生能源跨区域消纳,综合考虑电网稳定性和资源柔性,建立了输电线路布局多目标优化模型。确定了六大区域间输电线路的最优线路路线、11种直流和交流输电技术的技术选择、输电容量和完成时间。结果表明,与2018年相比,2039年西北电东送和北电中送的输电能力将分别提高265 %和160 %。从2033年开始,800 ? kV ( 10 GW )直流将成为主要输电技术。线路施工完成的高峰期将为2036—2039年。我国中东部地区风电和太阳能装机容量比重增长最快。2039年这些地区风电和太阳能装机容量的比例将是2018年的4 - 6倍。增加储能和改善需求侧响应可分别使在网可再生能源发电量增加1.7 %和2.6 %；但这将导致新建线路分别减少2 - 6条和7 - 9条。

原文：To eliminate power transmission bottleneck and improve cross-regional consumption of renewable power in China, a multi-objective optimization model for transmission line layout is established by considering grid stability and the flexible resource. The optimal line route, technology selection among eleven types of direct current (DC) and alternating current (AC) transmission technologies, transmission capacity, and completion time of inter-regional transmission lines among the six major regions are determined. The results show that power transmission capacity of Northwest-to-East and North-to-Central will increase by 265% and 160%, respectively, in 2039, compared with that in 2018. DC of 800 kV (10 GW) will become the main transmission technology from 2033. The peak period of the line-construction completion will be 2036–2039. The central and eastern regions have registered the fastest growth in the proportion of wind and solar power-installed capacity in China. The proportion of wind and solar power-installed capacity in these areas in 2039 will be 4–6 times that in 2018. Increasing energy storage and improving demand-side response can increase the on-grid renewable power by 1.7% and 2.6%, respectively; however, it will lead to a reduction of 2–6 and 7–9 newly-built lines, respectively.
