Event Overview

The Utility Wind Integration Group (UWIG) has been in the forefront of wind and solar integration and variable generation issues, opportunities and challenges for many years. This two-day workshop, with an optional virtual tour of the National Renewable Energy Laboratory (NREL) Energy Systems Integration Facility, planned for Friday February 24th, will answer your questions about interconnecting wind and solar plants and other distributed generation applications to electric distribution systems; and provide insight and understanding to integrating large scale renewable generation into the transmission system.

The workshop will provide an overview of wind and solar integration studies and common frequently asked questions; followed by case-study presentations on wind and solar project interconnection experiences. The workshop then moves into an introduction to the Utility Wind Integration Group's Internet-based tools designed to assess a distributed wind project's impact on the local distribution system. Training will cover the theory behind each tool and demonstrate their use with actual data.

Speakers from Tri-State G&T, Xcel Energy, NREL, Western and DOE will address topics beyond the distributed system, including transmission, energy imbalance markets, power operations training, and renewable integration studies.

Also, Western's Electric Power Training Center (EPTC) instructors will be there to offer a tour of the center. Participants will have the opportunity to observe a demonstration of the EPTC's hands-on miniature power system, which includes a Wind Farm Simulator developed in partnership with the National Renewable Energy Laboratory and the U.S. Department of Energy's Wind and Water Power Program.

The virtual tour of NREL's Energy Systems Integration Facility (ESIF) will describe the facility, scheduled for opening in the fall of 2012. The ESIF will provide laboratory and office space for approximately 200 NREL researchers and support staff who will engineer, design, test, and analyze components and systems to enable economic, reliable integration of renewable electricity, fuel production, storage, and building efficiency technologies with the U.S. electricity delivery infrastructure.

The staff will conduct research to overcome challenges related to the interconnection of distributed energy systems and the integration of renewable energy technologies into the electrical grid. The ESIF will also include a state-of-the-art, high-performance computing data center that will improve and expand capabilities in modeling and simulation of renewable energy and energy-efficiency technologies and their integration into the existing energy infrastructure.

Continuing education credit will be available for this workshop.
