Electric grid connection mapping

A non-transitory computer storage medium encoded with instructions that, when executed by one or more computers, cause the one or more computers to perform operations comprising

• obtaining a computer model of an electric power grid;
• generating a network graph representation of the computer model, wherein nodes of the network graph represent electric grid assets of the computer model and edges of the network graph represent wires connecting the electric grid assets;
• generating an initial prediction of links between nodes in the network graph by adding at least one edge to the network graph to obtain an over-connected network graph;
• applying the over-connected network graph as input to a machine learning model to obtain an annotated network graph, the machine learning model configured to identify edges as positive links and negative links, and apply annotations to the edges indicating whether each edge is a positive or a negative link;
• and
• updating the computer model based on the annotated network graph.

A system comprising one or more computers and one or more storage devices on which are stored instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
