This symposium was cohosted by Sandia National Laboratories and the Electric Power Research Institute (EPRI).

The 2013 PV Systems Symposium included three workshops:

  • Operations and Maintenance (O&M) Workshop (Monday, April 29 2013) (Agenda)The 2013 PV Operations and Maintenance Workshop, hosted by Sandia National Laboratories and EPRI, included a full day of interactive presentations, brainstorming, and dialog to both explore current knowledge gaps and lay the groundwork for industry standards and protocols. The fully subscribed event—attended by O&M providers, system integrators, independent power providers, independent engineers, utilities, and laboratory and university representatives—examined the tools, techniques, and data analysis approaches that can enable operational improvements and high levels of reliability.Topics of discussion surrounded the identification of key PV O&M challenges, as well as their potential operational and cost impacts; planning required for characterizing reliability through data and metrics; and predictive methods for reducing O&M risk. Information was conveyed through case studies, panel debate, and breakout session ideation.Please feel free to access the workshop’s agenda and associated proceedings via this web page. Over the next several years, Sandia and EPRI will be jointly spearheading the development of PV O&M standards. We encourage your participation! If you are interested in joining one of our Working Groups, contact: Roger Hill, rrhill@sandia.gov. Meantime, we encourage continued interaction on this important subject matter area and look forward to potentially convening similar workshops in the future.

 

 

IEEE PV Specialists Conference

Instructors: Cliff Hansen, Joshua Stein, and Dan Riley, Photovoltaic Modeling and Analysis Team, Sandia National Laboratories

Rob Andrews, Developer of PV_LIB for Python, Calama Consulting

This tutorial will provide attendees with a basic understanding of the modeling steps required to predict PV system performance from weather information. The series of modeling steps may include irradiance translation to plane-of-array, irradiance to DC energy conversion, DC to AC energy conversion, cell temperature estimation, and shading or reflection effects. Explanations of modeling procedures will be demonstrated using Sandia National Laboratories’ PV_LIB photovoltaic modeling toolboxes for MATLAB and Python; knowledge of MATLAB and Python programming is not required, but will be very useful in understanding the demonstrations.

Sandia participates in the 5th International Conference on Integration of Renewable and Distributed Energy Resources

The 5th edition of the Integration of Renewable and Distributed Energy Resources (IRED) conference took place in Berlin, Germany, on December 3-7, 2012. This conference provided a unique forum for an interdisciplinary and international discussion on the policy, regulatory/market issues, and technical aspects of integrating solar, as well as other renewable and distributed resources, onto the grid. Sandia National Laboratories co-chaired the conference, and organized several workshops on PV grid integration and smart grid. View Conference proceedings here. Proceedings for the previous edition of the conference can be accessed here.
