    Abstract: A computer-implemented method executed by one or more processors includes receiving interconnection data for a proposed interconnection to a power grid; accessing a power grid model including a topological representation of the power grid, electrical specifications of grid components, and empirical operation characteristics; and generating, using the interconnection data for the proposed interconnection to the power grid, and the power grid model, simulated power grid data. The simulated power grid data is based on simulating operation of the power grid with the proposed interconnection coupled to a location of the power grid identified by the interconnection data during a simulated time period. The simulated power grid data includes a plurality of different temporal and spatially dependent characteristics of the power grid. The method includes evaluating, using one or more metrics, the simulated power grid data; and outputting evaluation results of the one or more metrics.
