Abstract: The poor compatibility between distribution equipment and new intelligent terminals affects the accuracy and real-time performance of data collection and transmission, limiting the full realization of integrated control functions. Therefore, this paper delves into the integrated control technology for distribution networks under the smart grid architecture, designing a hierarchical distributed overall architecture that includes the information perception layer, data transmission layer, decision analysis layer, and execution control layer. By deploying intelligent devices to achieve real-time data collection, constructing communication networks, and relying on AI algorithms to assess grid status and issue fault warnings, the system achieves precise equipment control through automation technology. Experiments show that this system effectively addresses challenges such as data processing and collaborative control in distribution network operations, providing technical support for efficient operation of distribution networks and enhancing the capacity to integrate renewable energy. This has significant theoretical and practical implications for promoting the development of smart grids.
