The reporter learned from the National Energy Administration on December 31 that the guidance on promoting the high-quality development of the power grid jointly issued by the National Development and Reform Commission and the National Energy Administration proposed that by 2030, the main power grid and distribution network will be the important foundation. A new power grid platform with smart micro-grid as a useful supplement has been initially completed.
in addition, the opinion proposes to effectively enhance the optimal allocation of power grid resources by 2030, with the scale of "west-to-east power transmission" exceeding 0.42 billion kilowatts, adding about 40 million kilowatts of inter-provincial power mutual aid capacity, supporting about 30% of new energy power generation capacity, 0.9 billion kilowatts of distributed new energy capacity, and supporting more than 40 million charging infrastructure.
As a hub platform connecting power production and consumption, the power grid is the core link to accelerate the construction of a new power system. At present, China's power grid has become a super large power grid with the strongest transmission capacity, the highest operating voltage level, the largest scale of new energy grid connection and the longest safe operation record in the world. The ability to optimize the allocation of power grid resources leads the world, and the scale of "power transmission from west to east" reaches 0.34 billion kilowatts, accounting for about 23% of the country's maximum power load in 2025.
opinions clarify the tasks and measures from seven aspects: clarifying the functional orientation of the new power grid platform, strengthening the unified planning and construction of power grids at all levels, building a new power dispatching system, enhancing the security and governance capability of the power grid, promoting the development of the power grid with new quality productivity, promoting the all-round service of the power grid to ensure people's livelihood, and strengthening the supervision and management of the power grid.
It is proposed to optimize the coordinated development pattern of the main distribution microgrid, promote the planning and construction of cross-provincial and cross-regional transmission channels in an orderly manner, optimize and upgrade the main grid structure of the power grid, accelerate the construction of a new distribution system, plan and build smart microgrids according to local conditions, and increase investment in the power grid.
"The main distribution microgrid collaboration builds an important platform for the development of new power formats." Zhang Lin, director of the Planning and Development Department of the China Federation of Electric Power Enterprises, said that with various new formats connected to the power grid at various voltage levels, the power grid form has gradually evolved from a one-way step-by-step transmission network for transmission and distribution to a multi-directional hybrid structure network. The hub platform role of the power grid has become increasingly prominent, supporting the large-scale development of new power formats. It is necessary to enhance the interaction capability of the main power grid, distribution network, distribution network and microgrid and microgrid, support the efficient operation of various new formats and equal participation in the electricity market.
