摘要
提出碳达峰、碳中和目标是国家做出的重大战略决策,事关全社会可持续发展和构建人类命运共同体,构建新型电力系统是实现碳达峰、碳中和目标的重要举措。本文对已有研究成果中新型电力系统的内涵、特征、典型场景预测、实施路径等四个方面进行了归纳总结,梳理了构建新型电力系统应满足的安全、低碳、经济等基本要求,分析了典型场景中各类电源装机规模及发电量的构成,指出在新型电力系统构建实施路径中应重点考虑煤电有序退减、新能源科学高速渗透和灵活性资源合理配置,其中煤电退减应按照先慢后快的路径进行,新能源的高速渗透应考虑系统的消纳能力。
China have made a major strategic decision to achieve carbon peaking and carbon neutrality goals,which concern the sustainable development of the whole society and the construction of the community with a shared future for mankind. Constructing new-type power systems is a crucial path to achieve the dual carbon goals.In this paper,we summarized the connotation,characteristics,typical scenario prediction,and implementation path of the new-type power system based on the current research results and proposed that the construction of the new-type power system should meet the basic requirements of safety,low carbon emission,cost-effectiveness,etc. In addition,we analyzed the composition of the installed scale of power generators and power generation capacity of various sources in the typical scenarios and pointed out that the construction and implementation path of the new-type power system should take orderly reduction of coal power generation,rapid growth of new energy market penetration and rational allocation of flexible resources into key considerations. Coal Power Generation Reductionshall be carried out according to the trend of slow before fast,and the absorption capacity of the system shall be considered for the high-speed penetration of new energy.
