Abstract

A system is provided that allows the aggregation of a plurality of inputs from an electrical grid and the display of the plurality of inputs on a single integrated display for a network operator. The system accepts signals from electrical loads and generation devices and analyzes the inputs to determine potential issues or trends, including fault predictions and recommends contingency plans. The system presents these potential issues and possible corrective actions to the network operator. The network operator may initiate actions, such as dispatching loads or activating generation capacity for example, in response.
