Abstract: Provided is a system and method for visualizing power components on a power grid via an arc diagram. The arc diagram can be an interactive diagram that enables an operator to perform a switching operation via the arc diagram. In one example, the method may include storing power measurements from a power grid and geographical topology data of devices on the power grid via a memory device, generating and displaying an arc diagram based on the geographical topology data, where the arc diagram comprises a plurality of nodes corresponding to a plurality of devices on the power grid which are arranged along a horizontal axis in the arc diagram, and arranging arc-shaped structures between the plurality of nodes on the horizontal axis based on the power measurements, where the arc-shaped structures represent power flows between the plurality of devices.
