Wire and Cable Show 2024 Industry Bulletin: Development and Advantages of Smart Grids
A smart grid is an integrated transmission and distribution system combining traditional modern power engineering technology, advanced sensing and monitoring technologies, and information and communication technologies. Wire and Cable Show 2024 has learned that the concept was first proposed by the "Smart Grid Working Group of the Future Energy Alliance" in the United States in 2003. The smart grid boasts enhanced performance, ensuring power supply and providing users with more reliable power services.
The advantages of smart grids lie in their significant improvements over traditional grids. Currently, most new energy power stations operate in a blind adjustment mode. By leveraging 5G "wireless" technology for deployment, smart grids successfully save on fiber optic laying costs and reduce environmental impact. More importantly, they support the integration of a large number of distributed energy sources, achieving "plug and play" functionality for distributed energy and further enhancing grid efficiency.
Wire and Cable Show 2024 noted four unique advantages of smart grids, which highlight their distinctive characteristics:
Self-healing capability: Allows the grid to automatically repair itself after damage.
Support for large-scale distributed energy integration: Meets diverse energy demands.
Real-time monitoring using various self-check devices: Visual management helps maintenance personnel better monitor and dispatch the grid.
Information-based distribution and consumption management: Enhances the intelligence level of the grid.
Since 2003, significant achievements have been made in the research and application of smart grids. The U.S. Department of Energy has funded several smart grid research programs, including GridWise, Grid2Works, and the Modern Grid Initiative (MGI), with many projects already achieving success in practical applications. For instance, CenterPoint Energy in Texas and San Diego Gas & Electric have begun implementing or planning smart grid projects. Additionally, as part of the U.S. Galvin Electricity Initiative, European countries are also actively promoting the research and application of smart grid technologies.
In summary, the outstanding performance and superior features of smart grids indicate their broad application prospects worldwide, foretelling that smart grids are indeed the future of power systems.
