Abstract:

The new power system driven by the "dual carbon" goal cannot adapt to the top-down energy/power balance mode at different temporal and spatial scales.Therefore, it is urgent to conduct relevant research on the construction path of the future power grid, particularly the distribution network. The micro-energy network, a comprehensive energy network with self-balance regulation ability, can leverage the pivotal role of power grids in promoting zero-carbon/low-carbon energy production and consumption and will play a pivotal role in future power grid transformation and upgrading. First, the evolution stages and modes of traditional distribution networks, active distribution networks, and future low-carbon distribution networks are summarized and compared. Second, based on the characteristics of "source-network-load" in the future, a type of future distribution network construction idea of bottom-up evolution layer by layer is proposed by constructing micro-energy network and utilizing the interconnection and interaction between micro-energy network units and distribution network. Additionally, a type of atomic future distribution network is introduced. Finally, future research directions for the evolution of distribution networks are discussed from different perspectives.

Key words: micro-energy network, bottom-up, intelligent interconnection, atomic future distribution network
