As the core of the energy Internet

the intelligent

transparent

and low-carbon development of the power system has become the top priority. In this paper

with the continuous improvement of the penetration rate of distributed renewable energy resources and the flexibility of various resources in the source network

the structural form and planning philosophy of the distribution system have new changes. Therefore

it is necessary to further study the planning system and technology suitable for the new-type distribution system. Firstly

the concept and characteristics of the source-load cluster in the power distribution system are introduced

and a new hierarchical architecture of power distribution system is constructed. Secondly

the multi-level decentralized cooperative planning framework for the distribution system is established

and its main application scenarios are summarized. Thirdly

based on the “planning-operation” nested structure

the key technologies and research approach of multi-level decentralized collaborative planning are sorted out in term of cluster division

primary system planning

and primary and secondary integration planning. Finally

the technical challenges and feasible solutions of multi-level decentralized cooperative planning for new-type distribution systems are prospected for the problem of endogenous uncertainty introduced into the preset scheduling mode in future planning scenarios and the multi-agent game-theoretic interactions under complex market mechanism.
