Abstract: With the increasing accommodation of single technology grid-connected entity and load aggregator, the active distribution networks are closely linked with the transmission networks. In this work, focusing on the high-quality development of distribution networks, the effect of grid structure, operation and control, coordination mechanisms on homogenization of transmission and distribution networks are analyzed. The main obstacles such as management mechanisms, technical systems, operation models, and standard norms are proposed. As for the novel dispatching system, the collaborative regulation and control of networks, the flexible resource collaborative invocation, the market mechanism construction and coordinated organization design and explored in detail. In terms of the joint operation and dynamic control, the multi-temporal-scale planning, the power and load forecasting and verification and the comprehensive assessment of the operation efficiency are investigated. Aimed to enhance the technologies, some main directions such as the stability of distribution networks, the data perception and information integration, and the grid self-healing and rapid isolation are discussed. The strategies for promoting the coordinated dispatch of transmission and distribution networks are systematically summarized. The important tasks of improving technical standards, constructing the technical system, and establishing management mechanisms were outlined.
