Susan Covino - Smart Grids and Microgrids


Published on

June 15, 2011

Susan Covino's presentation from America’s Sustainable Future: How U.S. Cities Are Making Energy Work, an invitational conference of public-private partnership efforts from U.S. cities pursuing innovative energy management and smart grid initiatives. The assembled leaders in industry, research and policy-making will explore the diverse energy strategies emerging in Philadelphia and across the United States.

“We’re really looking forward to both learning from the great examples set by other cities represented in the conference, and showing off the groundbreaking work happening right here in Philadelphia,” says Laurie Actman, Viridity Energy’s director of strategic partnerships and public policy.

“With smart ideas and smart policy, we should be able to build support for smart grid projects and microgrids at the federal, state and local level.”"Energy technology is changing at such a rapid pace, it's crucial to examine who's doing it right in smart grid and microgrid projects all around the country," says Eugenie Birch, Penn IUR co-director.

"With the right policy moves—which we'll be exploring at the conference—Philadelphia can be a national leader in energy innovation," noted Susan Wachter, Penn IUR co-director.

  • Key concept here is two-way communication & control…. Data from smart meters will help enable the Smart Grid, especially as it relates to operations and engineering to make decisions on both the outage response, transformer load management, and system planning. Future T&D uses for data from smart metering include: Load management/control for grid reliability Outage notifications Customer distributed generation monitoring and control Distribution transformer health monitoring Power quality monitoring
