Problems solved by technology

In the process of data analysis, processing and response, the traditional cloud computing model cannot meet the real-time requirements for information flow processing, which has a direct impact on the stability of energy flow and the reliability of control
On the other hand, at present, the optimization problem of traditional distribution network is mainly solved by centralized control, but the centralized control method is sensitive to faults, and its reliability is low, which has a certain impact on the robustness of cyber-physical systems, and has a certain impact on the robustness of cyber-physical systems. The changes brought about by the input and exit of distributed power sources cannot make a quick and timely response, and cannot guarantee the "plug and play" of distributed power sources
