Research Progress of Distribution Network Digitization Based on Digital Twin Technology

Digital twin technology plays an important role in the process of digital distribution network. By means of digital twin and situation awareness, the data flow of distribution network can be fully utilized so as to promote the development of new forms of virtual and real combination and twin interactive distribution network. Focusing on the characteristics of the above-mentioned digital twin and combining the characteristics of the distribution network, the key technology of the digital twin system of the distribution network is proposed, and several applications of the digital twin in the distribution network are discussed. Finally, its development is prospected. The future digital twin technology will enable the distribution network system and other links of the power system to develop in the direction of digitization, networking, intelligence, and transparency.
