Midwest Independent Transmission System Operator Smart Grid Project

From Open Energy Information

Midwest Independent Transmission System Operator, located in Carmel, Indiana, will receive $17 million in funding to develop a smarter energy grid. The U.S. Department of Energy selected Midwest Independent Transmission as one of 100 companies to receive federal stimulus funds as part of the American Recovery and Reinvestment Act of 2009.[2]

The Midwest Independent Transmission System Operator (Midwest ISO) is deploying synchrophasor technology throughout its service footprint. Midwest ISO’s primary objective is to use the technology to optimize the dispatch and operation of power plants while improving the reliability of the bulk transmission system. This project deploys phasor measurement units (PMUs), phasor data concentrators, and advanced transmission software applications. This technology increases the visibility of grid operators’ bulk power system conditions in near real time, enables earlier detection of conditions that could result in grid instability or outages, and facilitate information sharing with neighboring regional control areas. Access to better system operating information allows Midwest ISO engineers to improve power system models and analytical techniques, improving the overall reliability and operating efficiency of the Midwest ISO system.[3]
