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.

5th International Conference on Integration of Renewable and Distributed Energy Resources Conference Summary and Proceedings

SUMMARY: Testing and Analysis of Low Cost Composite Materials Under Spectrum Loading and High Cycle Fatigue Conditions

Achieving High Penetrations of PV: Streamlining Interconnection and Managing Variability in a Utility Distribution System

Friday, Sept 14, 2012, 8:00 am – 5:00 pm Orange County Convention Center, West Concourse ‐ Room 306A

This week at the Solar Power International Conference, the Department of Energy (DOE), the Electric Power Research Instisute (EPRI), Sandia National Laboratories, and the National Renewable Energy Laboratory (NREL) have joined forces in a workshop that will focus on PV systems operating in the utility system, and it will review operational issues, update interconnection rules and regulatory actions, address PV lessons learned from high penetration scenarios, identify best practices for distributed generation problem mitigation, discuss technology advancements including advanced inverters, consider forecasting tools for grid operators, and review case studies of industry experience. The workshop will address areas of common interest and is designed for PV developers, system integrators, utility distribution and interconnection engineers, inverter manufacturers, forecast providers, and those who work in codes, standards and regulation.

Utility Solar Conference (USC) 2012 High Penetration PV Grid Integration Workshop

April 19, 2012, Tucson, Arizona

Sandia National Laboratories joined the U.S. Department of Energy (DOE), Electric Power Research Institute (EPRI), Solar Electric Power Association (SEPA), and National Renewable Energy Laboratory (NREL) in conducting the High Penetration PV Grid Integration Workshop. The workshop brought together PV industry leaders to focus on key issues that utilities are facing with high penetration of distributed solar. Attendees reviewed and discussed the latest research in high penetration PV, integration standards, and the utilities’ efforts in distributed PV integration.
