About UVIG

The Utility Variable-Generation Integration Group, previously known as the Utility Wind Integration Group (UWIG), was established in 1989 to provide a forum for the critical analysis of wind and solar technology for utility applications and to serve as a source of credible information on the status of wind and solar technology and deployment.  The group’s mission is to accelerate the development and application of good engineering and operational practices supporting the appropriate integration and reliable operation of variable generation on the electric power system.

Did You Know – ISO New England Develops Innovative Computer Modeling Application to Help Grid Operators Reduce Dispatch Risk, Uncertainty, and Cost

With more than 350 power plants, 8,600 miles of high voltage transmission lines, and more than seven million electricity customers, running the six-state regional grid is a continuous balancing act. Therefore, dispatching power resources to reliably serve electricity demand is one of the most critical tasks in electric power system operations. But doing this efficiently and economically is getting increasingly challenging as more demand resources and weather-dependent wind- and solar-power resources come on line. These resources introduce unprecedented levels of uncertainty in real-time operations around how much power is going to be demanded from consumers or available to supply it.

To help our control room operators anticipate such uncertainty and dispatch the grid in the most reliable manner possible, ISO New England computer scientists and their partners have developed a pioneering risk management tool that quantifies uncertainty, uses a modeling framework to analyze it, and then provides an efficient unit commitment solution. This powerful computer application increases power system reliability and minimizes dispatch costs for a sizable savings, and remains effective even as uncertainty levels increase.

This advanced research, developed by ISO New England’s Business Architecture and Technology team members Drs. Eugene Litvinov, Jinye Zhao, and Tongxin Zheng, in collaboration with Dr. Xu Andy Sun from the Georgia Institute of Technology and Dr. Dimitris Bertsimas of the Massachusetts Institute of Technology, was originally highlighted in an IEEE Transactions on Power Systems journal paper entitled, “Adaptive Robust Optimization for the Security Constrained Unit Commitment Problem.”

U.S. Department of the Interior Releases National Interactive Map of Onshore Wind Turbines

The U.S. Department of the Interior and U.S. Geological Survey have released the first publicly available interactive map and geo-dataset showing more than 47,000 onshore wind turbine locations and related information across the entire United States

The wind turbine map, which includes turbines installed as of July 2013, was created by combining publicly available data sets from the Federal Aviation Administration , the U.S. Energy Information Administration , the Oak Ridge National Laboratory , as well as other federal, state and local sources. USGS researchers also identified additional turbines not in those pre-existing databases and added them to the dataset and map. The locations of all turbines were visually verified using high-resolution imagery. The location of each turbine was verified to within plus or minus 10 meters, and its technical specifications were assigned based on the make and model.

Why Join UVIG?

Featured Member Benefit

One of the key benefits of UVIG membership is participation in our User Groups. UVIG operates five topical user groups focused on specific areas of interest to its members:

  • Wind and Solar Plant Modeling and Interconnection
  • Operating Impact and Integration Studies
  • Distributed Generation Applications
  • Market Operation and Transmission Planning
  • Wind/Solar Plant Operations and Maintenance

These groups are open to all UWIG members (there are participation limitations for the O&M User Group). The concept is to gather together in one place all relevant information on that topical area, and make it easily available to the members. This information is housed in the member’s area of the site. Each user group has a listserv or mailing list that we use to distribute news, research reports, future events, and other information relevant to the user group’s scope. Because the User Groups cut across multiple groups within any company, we would like to encourage you to identify other individuals in your company who could benefit from participation in a User Group.  To subscribe yourself or others with your company to any of the user group listservs, please contact Sandy Smith, sandy@variablegen.org. Note that only those members that own/operate wind or solar generation can participate in the O&M listserv.
