清洁低碳发展背景下跨国互联电力系统规划方法

在全球应对气候变化清洁低碳发展的宏观背景下，当前跨国互联电力系统研究在地域范围、时间跨度、多层次协调等方面都存在一定不足。提出了协同有序完整的跨国互联电力系统规划研究体系框架，重点介绍情景设置、网源协同规划、环境气候-经济-社会效益分析等关键技术模型；基于“工作体系”和“支撑体系”，设计了总体工作流程；以实现《巴黎协定》温控约束为目标，对全球电力需求、电源结构、电能流动等问题开展了情景分析，评估研究综合效益。最后对规划研究方法进行了总结，并提出了提升建议。

Planning Methods for Transnationally Interconnected Power Systems under the Background of Clean Low-Carbon Development

Under the macro background of clean and low-carbon development for addressing global climate change, the current research on transnationally interconnected power systems has certain deficiencies in terms of geographic scope, time span, and multi-level coordination. We propose an orderly and coordinated framework for planning and research of transnationally interconnected power system, and introduces the key technical models such as scenario building, generation-grid collaborative planning, and environmental climate-economic-social benefit analysis. An overall work process is designed based on the “ work system” and “support system”. Taking the temperature limit of the Paris Agreement as the objective, a scenario analysis is carried out, including global power demand, power supply mix, energy flow and other issues, and the comprehensive benefits are evaluated. Finally, the planning research methods are summarized and relevant suggestions are proposed.
