Abstract: Under the dual carbon goal and with the high proportion of new energy with wind and solar as the main body connected to the distribution network, a collaborative planning method of source, grid, load and storage in a distribution network considering the multi-agent game is proposed. Firstly, the transmission relationships between the distributed power operators, the distribution network operators, the energy storage operators and the power users are analyzed. On this basis, the income models of these different entities are established. Then, a multi-agent game collaborative planning model of the distribution network considering the limited rationality of the stakeholders is constructed, and the optimal planning scheme of the distribution network frame, the distributed power source and the energy storage is decided on account of the demand response of the user side through the evolution games between the distributed power operators, the distribution network operators and the energy storage operators. Finally, the effectiveness of the proposed method is verified by a simulation example. The results show that the proposed method is able to effectively coordinate the planning of the grid frame, the distributed power source and the energy storage, and determine the scheme for the users to participate in the demand-side response so as to improve the economy of the planning and promote the absorption of the new energy. At the same time, the game relationships and the limited rationality of the stakeholders are considered, and the interests of the multiple subjects are also taken into account, the planning results closer to reality.
