AI Technical Summary

Problems solved by technology

With the growth of power demand and the expansion of power grid scale, multiple independent communication room networks are often deployed in adjacent areas, lacking a linkage mechanism between different networks, and it is difficult to meet the development requirements of future smart grid interconnection and control integration.

[0004] At the same time, although there are a large number of literatures on the robust optimization of network communication in the existing technology, there is no network construction method that takes into account the robustness and construction cost, and is aimed at the network characteristics of the power information communication room.
