Deep dives
Challenges of Power Outages
A significant issue in transitioning to renewable energy is the frequent power outages experienced by households, with one in four facing an outage each year. These outages can occur due to various factors, including severe weather events like hurricanes, which can lead to extensive damage to power lines and infrastructure. The costs associated with investigating these outages are substantial, often exceeding $1,500 just for the initial investigation, not including repairs. Moreover, line workers face dangers when they must search for problems, risking electrocution or injury in challenging environments, highlighting the urgent need for solutions to improve grid reliability.
The Role of Drones in Grid Inspections
To enhance the efficiency of power line inspections, researchers are developing drones that can automate the process. These drones are designed to conduct initial assessments known as 'scouts,' equipped with various sensors to detect issues such as crackling insulators or other faults along the lines. Utilizing a system of GPS coordinates and algorithms, drones can be dispatched quickly to inspect specific areas of the grid, reducing the need for manual checks by line workers. This technology not only aims to save time and costs but also to improve safety by minimizing the exposure of workers to hazardous conditions.
Implementing a Smart Electrical Grid
The innovation of a smart electrical grid combines advanced software and sensors to monitor and manage electrical distribution more effectively. Central to this system is the SCADA (Supervisory Control and Data Acquisition) technology, which allows for real-time data acquisition and operational control of the grid. By integrating sensors and automated systems, utilities can receive immediate updates on grid conditions and respond proactively to potential issues. The goal is to transition this drone technology from research to practical application, with demonstrations anticipated within the year to showcase its capabilities and readiness for wider implementation.
One in four U.S. households experiences a power outage each year. Scientists at Oak Ridge National Laboratory are working on technology they hope will help fix electric grids: drones. They're betting that 2-ft. large drones connected to "smart" electric grids are a cost-effective step to a more electrified future.
