Role of AI in enhancing grid and asset hardening

Executive Summary (tl;dr)

• With the increase in natural phenomenon that affect the grid, strategic spending on grid and asset hardening is key 
• AI can help ensure the right amount of money is spent on the right infrastructure

The modern power grid delivers electricity across vast distances and to millions of homes and businesses. However, it faces increasing challenges from natural disasters, cyber-attacks, and aging infrastructure. Grid and asset hardening, the process of making the grid more resilient to these challenges, is critical to ensuring a reliable power supply. Artificial Intelligence (AI) offers innovative solutions to enhance hardening efforts, providing utilities with powerful tools to predict, prevent, and respond to disruptions.

Understanding grid and asset hardening

Involves a series of upgrades and improvements to the power grid to make it more robust and less susceptible to failures. Key components of hardening include:

1. Asset Upgrades: Strengthening transmission towers, poles, and lines to withstand extreme weather events like hurricanes, ice storms, and wildfires.
2. System Redundancy: Implementing redundant systems and alternative power pathways to ensure electricity can be rerouted during outages.
3. Advanced Monitoring and Control: Deploying sensors, smart meters, and automated controls to monitor grid conditions in real-time and quickly respond to issues.
4. Cybersecurity Enhancements: Protecting the grid from cyber threats through advanced security measures and continuous monitoring.

The role of AI in grid hardening

Artificial Intelligence can significantly enhance grid hardening efforts by providing utilities with advanced capabilities for data analysis, prediction, and automation. This is crucial as the number of billion dollar disasters affecting places like the United States is growing YoY. These disasters can set back local grids millions of dollars and weeks without power if no precautions are taken to harden the grid and systems.

1. Predictive Maintenance
   • Challenge: Aging infrastructure is prone to failures, leading to unexpected outages and costly repairs.
   • AI Solution: AI algorithms analyze data from sensors and historical maintenance records to predict when and where equipment is likely to fail. This allows utilities to perform maintenance proactively, reducing the risk of unexpected failures and extending the life of critical infrastructure.
2. Weather Forecasting and Disaster Preparedness
   • Challenge: Extreme weather events can cause widespread damage to the grid, leading to prolonged outages.
   • AI Solution: AI-enhanced weather forecasting models provide more accurate and granular predictions of extreme weather events tied to asset locations in a single view. This enables utilities to take preemptive measures, such as reinforcing vulnerable infrastructure, pre-positioning repair crews, and adjusting grid operations to mitigate the impact of storms, heatwaves, or other extreme conditions.
3. Fault Detection and Isolation
   • Challenge: Quickly identifying and isolating faults in the grid is crucial to minimizing the impact of outages.
   • AI Solution: AI-powered systems continuously monitor grid conditions and use machine learning algorithms to detect anomalies and faults in real-time. When a fault is detected, AI can automatically isolate the affected section of the grid, preventing the issue from cascading and causing broader outages. This rapid response helps restore power more quickly and efficiently.
4. Optimizing Grid Operations
   • Challenge: Balancing supply and demand while maintaining grid stability is a complex task, especially with the integration of renewable energy sources.
   • AI Solution: AI optimizes grid operations by analyzing vast amounts of data from various sources, including generation, consumption, and storage. AI algorithms can predict demand patterns, optimize the dispatch of generation assets, and manage energy storage systems to ensure a stable and reliable power supply. This is particularly important as the grid becomes more decentralized and integrates more renewable energy sources.
5. Enhancing Cybersecurity
   • Challenge: Cyber threats pose a significant risk to grid stability and reliability.‍
   • AI Solution: AI enhances cybersecurity by monitoring network traffic for unusual patterns and detecting potential cyber threats in real-time. Machine learning algorithms can identify and respond to cyber threats faster than traditional methods, providing an additional layer of protection for critical grid infrastructure.

Application: SCE uses AI-driven predictive analytics to monitor and maintain its vast network of power lines and equipment. By analyzing data from sensors and historical maintenance records, SCE can predict equipment failures and schedule maintenance before issues arise, improving reliability and reducing costs.

National Grid

Application: National Grid has implemented AI-based weather forecasting models to enhance its disaster preparedness and response capabilities. These models provide more accurate predictions of extreme weather events, allowing National Grid to take proactive measures to protect its infrastructure and minimize the impact of storms and other natural disasters.

Duke Energy

Application: Duke Energy uses AI to optimize grid operations and integrate renewable energy sources. AI algorithms analyze data from across the grid to predict demand patterns, optimize the dispatch of generation assets, and manage energy storage systems. This helps Duke Energy maintain grid stability while increasing the use of renewable energy.

AI offers transformative potential for grid hardening, providing utilities with advanced tools to enhance resilience and reliability. By leveraging AI for predictive maintenance, weather forecasting, fault detection, grid optimization, and cybersecurity, utilities can better protect their infrastructure and ensure a stable power supply for the future. As the grid evolves to meet new challenges, AI will be a critical component in building a smarter, more resilient, and more sustainable energy system.
