Machine learning system for reliable prediction of power grid failures

This technology is a machine learning platform that can be used for determining the likelihood of failures in power grid components based on historical and real-time data.

Unmet Need: Proactive power grid maintenance for enhanced reliability

The aging power grid infrastructure in major US cities is responsible for frequent failures and power outages. Without a robust method to identify key vulnerabilities in the power grid, maintenance is limited to dealing with failures, resulting in higher operating costs and reduced reliability. The implementation of smart power grids enabling proactive maintenance will require systems capable of prioritizing repair tasks through the analysis of tremendous amounts of past and real-time data. As a result, a need exists for proactive and predictive maintenance programs that can utilize existing data resources for electrical grid reliability.

The Technology: Machine learning system for predicting power grid failures

This technology is a statistical machine learning system that uses historical and real-time data collected by the utility company to predict the risk of failure in the power grid. The system generates vulnerability rankings and mean time between failure (MTBF) estimates for various components of the power grid such as cables, terminators, manholes, and transformers, which can be used to prioritize maintenance work proactively before breakdowns occur. Modules of this technology can be conveniently integrated into corporate management platforms to enhance cost-benefit analyses, maintenance planning, and effort allocation.

This technology has been validated by Consolidated Edison Company of New York, Inc. through direct application to the New York City power grid.

Applications:

  • Statistical model for proactive decision-making systems
