Research Progress and Prospect of Key Technologies on Flexible Interconnected Devices

Distribution network flexibility is an effective solution to coordinate all kinds of sources and loads in the distribution system and improve the overall operation level of the system. The flexible interconnected device (FID) is the core device to realize flexible distribution network. In recent years, relevant researches on FID operation control have been widely carried out and rich achievements have been achieved. Starting from the structure of FID ontology, this paper combs the different forms of FID topology and corresponding advantages and disadvantages. On this basis, the key technical problems of flexible distribution network with FID as the core in different stages such as operation optimization, fault self-healing, configuration planning, etc.
