Problems solved by technology

[0003] At present, the coordinated optimal dispatch of the active distribution network is based on the hierarchical management characteristics of the distribution network operation, and the hierarchical optimization and coordination of the distribution network is carried out, and the coordination between different levels is realized by uploading the dispatchable capacity and issuing the optimization target curve. , this deterministic optimization strategy based on time points cannot meet the needs of a large number of random and intermittent distributed power access, so a multi-time scale coordinated optimization scheduling technology is proposed to achieve optimal allocation of resources within the active distribution network
