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.

Abstract: Methods, systems, and apparatus, including medium-encoded computer program products, for configuring location-specific electrical load models while preserving privacy. A first machine learning model configured to predict electrical load curves of an electrical utility grid can be obtained from a server. Load values associated with a particular region of the electrical utility grid can be obtained. The load values can be applied as calibration input to the first machine learning model to produce first adjustment parameters for the first machine learning model. The first adjustment parameters can be provided to the server.

Abstract: Methods, computer systems, and apparatus, including computer programs encoded on computer storage media, for training a classification neural network. The system generates, from a set of object-specific data, one or more meta-learning datasets for one or more respective initial training tasks. The system determines values for a set of meta parameters by performing meta-learning with a classification neural network on the one or more meta-learning datasets. The system obtains a set of labeled training examples for a characteristic-detection task. The system determines based at least on one of the values for the set of meta parameters and using the set of labeled training examples, target values for the network parameters for the classification neural network to perform the characteristic-detection task.
