Residential Building Frequency Regulation Data from Hardware-in-the-Loop Tests

Results from a hardware-in-the-loop implementation testing the potential of residential buildings to provide frequency regulation services for the electric power grid. It includes data from simulated homes and a physical laboratory home coordinated via a grid aggregator, showing aggregate response to regulation signals on a timescale of seconds. The data is structured with columns for timestamp, topic ID, and value string.

Use Cases

• Analyze the correlation between TS (timestamp) and VALUE_STRING to model the aggregate response of buildings to grid frequency signals.
• Segment VALUE_STRING data by TOPIC_ID to compare the performance of different simulated home configurations or device types.
• Use TS and VALUE_STRING to train time-series models for predicting building cluster responsiveness to demand response requests.

Strengths

• Data originates from the National Renewable Energy Laboratory's (NREL) Energy Systems Integration Facility (ESIF), a controlled research environment.
• The dataset captures real-time hardware-in-the-loop interactions between a physical laboratory home and simulated homes.
• The data schema enforces uniqueness with a constraint on the combination of TS and TOPIC_ID.

Limitations

• The number of rows, columns, and overall data size are unknown, making it difficult to assess scale.
• The dataset's description is technical and specific to an experimental setup, which may limit generalizability.
• Sample data is unavailable, preventing preview of VALUE_STRING content or data distributions.
