The energy situation is tight

the traditional power supply model with high energy consumption

high pollution and high emissions is accelerating the transformation.The “30·60” dual-carbon strategy and the goal of “building a new power system with the distributed energy as the main body” are the new direction of power grid.The wide application of new energy sources has brought new opportunities for the development of power grids

but its output uncertainty and intermittent issues have also brought new challenges.As the transitional stage of the smart distribution network and the energy Internet

the active distribution network has undergone considerable development since it was proposed in 2008.On this basis

this article upgrades the 10 kV voltage level to the 220 kV urban active power grid

enriches the connotation and technical framework

expounds key technologies and implementation ideas

and proposes a construction evaluation system of “three platforms and eight aspects”.Finally

the development of the digital active power grid is prospected.
