我国将投入超5万亿元建设新型电网

"十五五"时期，我国将投入超过5万亿元建设新型电网，远超"十四五"规模 12。国家能源局电力司副司长谭洪江介绍，新型电网建设将在架构、技术、服务三个方面进行升级迭代 1。

在架构层面，电网将形成主干电网和配电网为重要基础、智能微电网为有益补充的新架构 1。到2030年，配电网综合承载能力将实现翻倍，具备9亿千瓦分布式新能源接入能力 2。同时，"十五五"期间力争建成投产15回以上输电通道，到2030年"西电东送"规模超过4.2亿千瓦，新增省间电力互济能力4000万千瓦 2。

在技术创新方面，新型电网将应用人工智能、柔性构网、长时储能等新技术，以应对年均5%左右的电力需求增速和新能源装机增加的接纳需求 1。到2030年，虚拟电厂最大调节能力超过5000万千瓦，抽水蓄能规模达到1.6亿千瓦左右，新型储能规模达到3亿千瓦，全国充电设施规模总量超过4000万个 2。

在服务层面，新型电网将适配算电协同、绿电直连等新业态 1。到2030年新型电网将初步建成，高效支撑28亿千瓦以上新能源消纳 2。

China will invest more than 5 trillion yuan during the "15th Five-Year Plan" period to construct a new-generation power grid, substantially exceeding investment levels from the previous planning cycle 12. The initiative aims to preliminarily establish this modernized grid system by 2030, capable of supporting the integration of over 2.8 billion kilowatts of new energy capacity 2.

The new-generation grid represents a comprehensive upgrade across three dimensions: architecture, technology, and services 1. Structurally, the grid will feature a backbone transmission network and distribution network as its foundation, supplemented by intelligent microgrids 1. Technologically, the system will incorporate artificial intelligence, flexible grid-forming capabilities, and long-duration energy storage solutions 1. In terms of services, the grid will accommodate emerging business models including algorithm-power coordination and direct green electricity connections 1.

During the "15th Five-Year Plan" period, China plans to construct at least 15 new ultra-high-voltage transmission corridors, with "West-to-East Power Transmission" capacity projected to exceed 420 million kilowatts by 2030 2. The nation will add 40 million kilowatts of inter-provincial power exchange capacity 2. The distribution network's integrated capacity is expected to double by 2030, enabling integration of 900 million kilowatts of distributed renewable energy 2. By 2030, virtual power plant peak regulation capacity is targeted to surpass 50 million kilowatts, with pumped-storage hydroelectricity reaching approximately 160 million kilowatts and new-form energy storage reaching 300 million kilowatts 2. The country plans to deploy over 40 million charging facilities nationwide by 2030 2. These investments respond to China's projected electricity demand growth of approximately 5 percent annually while accommodating the expanding renewable energy capacity 1.
