National and International working groups have been established to accelerate the penetration on solar into the grid, they are composed of representatives from industry organizations, solar companies, national laboratories, and federal agencies. Below are the working groups supported by DOE to address issues pertaining to the challenges and solutions of increasing high penetration solar on the electric grid per the goal of the DOE SunShot Initiative.
National Working Groups
Utility Variable-Generation Integration Group (UVIG) Solar User Group
Chairs: Abraham Ellis, Sandia National Laboratories, and Debbie Lew, National Renewable Energy Laboratory (NREL)
Following on the success of the Photovoltaic (PV) Variability Workshop held October 2009 in cooperation with DOE, NREL, Sandia, and the Solar Electric Power Association (SEPA), as well as the expansion of its technical portfolio to include solar topics, UVIG held the inaugural meeting of its Solar Integration User Group on April 14, 2010, in Portland, Oregon.
Presentations from this meeting can be found in the member’s area of the UVIG website. Note that login credentials are required to access this site.
Chair: John McDonald, National Institute of Standards and Technology (NIST)
The Smart Grid Interoperability Panel (SGIP) supports NIST in fulfilling its responsibilities under the 2007 Energy Independence and Security Act. The SGIP will identify, prioritize and address new and emerging requirements for Smart Grid standards. It will further develop the NIST Framework and Roadmap for Smart Grid Interoperability Standards, Release 2.0, which was released February 2012.
International Working Group
Chair: Barry Mather, NREL
The International Energy Agency (IEA) Task 14 activities focus on high penetration of PV systems in electricity grids, mainly addressing the technical issues related to high penetration PV. DOE and its partners actively participate in this committee.
The main goal of Task 14 is to promote the use of grid-connected PV as an important source in electric power systems on a high penetration level where additional efforts may be necessary to integrate the dispersed generators in an optimum manner. The aim of these efforts is to reduce the technical barriers to achieving high penetration levels of distributed renewable systems on the electric power system. Because a number of distribution system issues related to integration are emerging first for PV systems, Task 14 focsues on working with utilities, industry, and other stakeholders to develop the technologies and methods that will enable the widespread deployment of distributed PV technologies into the electricity grids.
The objectives of this task are to:
- Develop and verify mainly technical requirements for PV systems and electric power systems to allow for high penetrations of PV systems interconnected with the grid
Discuss the active role of PV systems related to energy management and system control of electricity grids.
Technical issues include energy management, grid interaction, and penetration-related aspects related to local distribution grids and central PV generation scenarios.
