Many of the world’s transmission systems are already equipped with SCADA/EMS (energy management systems), substation automation, utility communications and FACTS (flexible AC transmission systems). Some even have wide-area monitoring systems coupled with phase-shifting transformers to detect and respond to disturbances in a large-area grid. All of these technologies are available from ABB, along with HVDC, which is particularly important for the stable incorporation of renewables into the grid. These tried and tested solutions will continue to serve in the smart grid, but there will be more of them and they will be more sophisticated. ABB currently offers a full, state-of-the art portfolio for intelligent transmission systems and is working hard to maintain its technological lead for the future.
