Experts from Sandia National Laboratories taught a Renewable Energy Integration Course at the University of Vermont in July 2011. The one-day course was designed to give representatives from utilities and energy technology companies as well as graduate-level students a snapshot of the current energy infrastructure, the potential effects from integration of renewable energy technologies, and the advances which will allow renewables to interact with smart grid architecture. Presentations are available below.
The course is part of a partnership recently formed between Sandia and the university. The collaboration is intended to enhance multidisciplinary education and workforce development appropriate for a smart electricity infrastructure sector; promote research collaborations to further smart grid deployment; and form liaisons with private and public stakeholders to encourage information sharing, technology transfer and job growth in the electric power sector.

The U.S. Department of Energy (DOE) and DOE’s Sandia National Laboratories recently hosted a workshop to discuss photovoltaic (PV) inverter reliability at the utility scale. Attendees included inverter manufacturers, integrators, utilities, independent engineers, and national laboratory and academic researchers.
The goals of this workshop included:
These objectives are aligned to advance the industry-wide goal of making PV a significant part of the U.S. electricity generation portfolio and to support DOE’s missions to mitigate risk, reduce Levelized Cost of Energy, and improve the appeal of solar energy systems by quantifying connections among initial cost and performance, long-term reliability, and O&M.
The workshop was supported by the U.S. Department of Energy’s Solar Energy Technologies Program.

Sandia and EPRI hosted the 4th International Conference on Integration of Renewable and Distributed Energy Resources December 6-10, 2010 at the Hyatt Regency in Albuquerque, New Mexico, USA. This prestigious event was jointly organized by the Electric Power Research Institute, Sandia National Laboratories and Natural Resources Canada. Sandia led the Scientific Committee, responsible for arranging the conference agenda.
This bi-annual international conference brought together North American, Asian, and European leading researchers and practitioners in the fields of renewable energy (RE) and distributed energy resources (DER) integration. Discussions focused on technical, market, and regulatory issues that challenge the integration of distributed and renewable energy resources into the electric grid.

Sandia National Laboratories hosted a workshop to discuss photovoltaic (PV) performance models. Research has demonstrated that models are not consistent in performance projections, especially for technologies other than crystalline silicon, and that there is a general lack of public data comparing modeled to measured performance. This has a direct effect on the PV market, where those involved in purchasing or financing PV systems face uncertainty regarding expected performance and may make decisions based on inaccurate results.
Specific objectives of the workshop were to review the current state-of-the-art in PV performance modeling, perform a comparison of PV performance models, including comparison to measured data, and discuss next steps to improve model accuracy and appropriate application. Participants included PV manufacturers, integrators, independent engineers, modelers, researchers, consultants, and analysts, as well as representatives from universities, government, and national laboratories.
The workshop was supported by the U.S. Department of Energy.

La Ola is a single-site 1.2 MW solar photovoltaic (PV) farm located on the island of Lana’i, Hawaii. The site is a pioneering high-penetration grid-tied PV and includes use of cutting-edge smart grid communications and controls that are being evaluated by Sandia researchers. The site will include a wind farm once complete. An opportunity to tour La Ola was offered as an addendum event at IEEE’s Photovoltaic Specialists Conference in 2010 and included summary presentations (available below) detailing the site’s technical accomplishments, daily operation, and future plans.
La Ola is part of the “Lana’i 100% Renewables” project of the Hawaii Clean Energy Initiative, a partnership of the state of Hawaii and the U.S. Department of Energy.

The U.S. Department of Energy (DOE) and Sandia National Laboratories hosted a workshop specifically for PV system integrators in 2010. The goal was to discuss ways to mitigate risk and improve appeal of solar energy by quantifying the connection between long-term reliability and operations and maintenance costs, service contracts, warranties, call-backs, and other integrator functions.
During the workshop, integrators from a variety of companies utilized their expertise and experience in interactive case studies and exercises. The results of the workshop will help DOE and national laboratory staff foster development of performance and system lifetime models aimed specifically at integrator needs. Based on participant feedback, discussions and models created following the workshop may address factors such as financing, PPAs, site assessment, education, component testing and monitoring, system design, and California’s 10-year warranty requirement.
This workshop was funded by DOE in support of its goal to achieve a competitive Levelized Cost of Energy for PV systems.
