The smart distribution network is based on distribution automation technology, applies advanced measurement and sensing technology, computer and control technology, information communication technology, and uses intelligent switching equipment and distribution terminal equipment. Distribution automation refers to the use of technologies such as smart devices, advanced software, and communication networks to automate the management and operation of distribution systems. Distribution automation involves the use of automated systems to monitor, control, and manage the. A broad definition of Distribution Automation includes any automation which is used in the planning, engineering, construction, operation, and maintenance of the distribution power system, including interactions with the transmission system, interconnected distributed energy resources (DER), and. To enhance the reliability and resilience of power systems and achieve reliable delivery of power to end users, smart distribution networks (SDNs) play a vital role. The conventional distribution network is transforming into an active one by incorporating a higher degree of automation. The distribution network is the portion of the entire power system that directly. To achieve a distribution system self-healing against power outages, emerging technologies and devices, such as remote-controlled switches (RCSs) and smart meters, are being deployed.
