Introduction to FedGNN

FedGNN, short for Federated Graph Neural Network, is an innovative approach designed to predict electric power loads by leveraging the distributed data stored across various clients without compromising data privacy. This method is rooted in the combined strengths of federated learning and graph neural networks (GNNs). Federated learning enables model training across multiple decentralized devices or servers holding local data samples, without exchanging them. This ensures data privacy and security by design. GNNs, on the other hand, excel in processing data structured in graphs, capturing the complex relationships and interactions within the electrical grid's topology. An exemplary scenario illustrating FedGNN's application involves multiple electric utility companies wishing to enhance their power load forecasting accuracy. These companies, each possessing localized data regarding their respective regions' electric load, collaborate to train a collective model. By doing so, they benefit from the aggregated knowledge derived from the entire network without directly sharing sensitive data. This federated graph-based model accurately predicts load demands by understanding the interconnected nature of the power grid, thereby optimizing electricity distribution and enhancing grid stability.

Main Functions of FedGNN

  • Data Collection and Normalization

    Example Example

    Collecting and normalizing electric power load data from smart grids across different regions.

    Example Scenario

    Utility companies collect diverse data, including load demands, weather conditions, and industrial outputs. This data is normalized to ensure consistency and prepare for further processing, enabling a comprehensive understanding of power usage patterns.

  • Graph Construction and Feature Aggregation

    Example Example

    Building a graph structure that represents the electric power system and aggregating neighbor features using GraphSAGE.

    Example Scenario

    Each utility company constructs a local graph where nodes represent transmission towers, and edges denote the power lines between them. Using GraphSAGE, a GNN architecture, features from neighboring nodes are aggregated to capture the local structural information within the electrical grid, facilitating the identification of critical load influencers.

  • Federated Learning on Super Nodes

    Example Example

    Forming super nodes through feature fusion and training a federated model across multiple clients.

    Example Scenario

    Utility companies identify key subgraphs within their local graphs, which are then fused into super nodes that encapsulate essential structural and feature information. These super nodes are used in a federated manner to train a global model that predicts electric power loads with high accuracy, leveraging cross-regional insights without exchanging raw data.

  • Global Graph Model Construction

    Example Example

    Creating a global graph structure by linking super nodes across clients and optimizing the model through edge pruning based on Pearson correlation coefficients.

    Example Scenario

    The federated model constructs a global graph by connecting super nodes from all participating clients, simulating inter-regional interactions. The model is refined by selectively pruning edges, focusing on the most significant connections to enhance prediction accuracy. This process allows utility companies to leverage collective intelligence for optimal load forecasting.
