Electronictization-a foundation for grid modernization

Abstract

Smart grid is the flag under which the US DoE has been mobilizing efforts to modernize the grid. Electronictization is the first step towards a smart modern grid. It is a process that transforms the grid from electrical and electromechanical (EE) to electronic, electrical and electromechanical (EEE), laying down the very basic foundation for the modern grid. All things grid connected (ATGC) has five groups of essential hardware: 1) Grid interface (smart) inverters; 2) Hardware for flexible AC transmissions; 3) Intelligent electronic power transformers (grid scale); 4) Solid-state circuit breaker, current limiters, smart fuses and sensors; and 5) Multi-port bidirectional power & control units. Development and deployment of ATGC will be a grassroots drive to transform the grid from an old passive technology to a new active technology based on electronic power transmission, distribution, processing and protection. Grid modernization represents a win-win-win situation for the environment (Government), consumers, and grid owners/operators.
