Real-Time Transmission Optimization
Electricity transmission congestion is a critical challenge to the nation’s electricity infrastructure that costs billions of dollars each year. There is a critical need to modernize the way electricity is delivered from suppliers to consumers. Modernizing the transmission grid through dynamic management techniques to tap into the unused capacity of transmission lines could help reduce peak congestion, increase the use of renewable energy, save money, and make the grid more resilient.
Project Innovation + Advantages:
Pacific Northwest National Laboratory (PNNL) is developing innovative high-performance-computing techniques that can assess unused power transmission capacity in real-time in order to better manage congestion in the power grid. This type of assessment is traditionally performed off-line every season or every year using only conservative, worst-case scenarios. Finding computing techniques that rate transmission capacity in real-time could improve the utilization of the existing transmission infrastructure by up to 30% and facilitate increased integration of renewable generation into the grid—all without having to build costly new transmission lines.
If successful, PNNL’s real-time transmission-rating technology could save businesses and consumers billions of dollars per year by reducing power generation costs, reducing transmission losses, minimizing transmission congestion costs, and deferring investment in costly new infrastructure.
A more efficient and reliable grid would be more resilient to potential disruptions from failures, natural disasters, or attacks.
Integrating more renewable power into the grid would result in a substantial decrease in carbon dioxide emissions in the U.S.—40% of which are produced by electricity generation.
A more efficient and reliable grid would help protect U.S. businesses from costly power outages and blackouts that stop automated equipment, bring down factories, and crash computers.
