Sandians Discuss Distributed Energy Interconnection and Interoperability

On February 26, 2024, Sandia National Laboratories staff were co-instructors for HalfMoon Education’s Distributed Energy Interconnection and Interoperability webinar. This webinar covered broader DER interconnection policy and technical standards content, plus narrower discussion specific to energy storage (ES) and Vehicle-to-Grid (V2G).  Sandia staff featured learning developed through Energy Storage (ES) program work within the Policy & Outreach and Safety & Reliability ES program thrust areas.

Will McNamara, Policy Analyst for the Sandia Energy Storage program, presented Trends in State-Level Policymaking. While Charlie Vartanian presented DER Interconnection Standards in Codes and Regulation, with an overview of industry activity updating IEEE 1547-2018 standard.

In supporting industry education events like this webinar, Sandia staff leverages and promotes ES program R&D products and resources. This and similar industry-facing activities also provide valuable industry feedback to inform continual refinement of ES program RD&D to best meet industry needs.

Sandians Lead Grid Storage Tutorial at 2024 IEEE Innovative Smart Grid Technologies Conference

On February 19, 2024, Sandia staff were co-instructors for the tutorial “How Grid Energy Storage Meets the Challenges of a Decarbonized Future”, at the 2024 IEEE Innovative Smart Grid Technologies conference in Washington DC.  This tutorial was organized and led by the IEEE Energy Storage and Stationary Battery (ESSB) technical committee.  Sandia staff, in support of the IEEE ESSB, covered tutorial sub-topics including Long Duration Energy Storage (LDES) technologies, Energy Storage (ES) economics, ES grid interconnection, and ES safety. This tutorial will be provided next at the IEEE T&D show May 6, 2024, in Anaheim CA.  A read description of that tutorial here.

In supporting IEEE ESSB, Sandia staff leverages and promotes Lab ES R&D learning and resources. The IEEE is also a productive community for technical information-exchange and socializing broader DOE initiatives including the Long Duration Storage Shot.

On February 6, 2024, the National Academy of Engineering (NAE) elected as a new member for his advancement of battery storage systems Dr. Babu Chalamala, Senior Scientist for the Grid Modernization and Energy Storage program at Sandia National Laboratories, announced NAE President John L. Anderson. In total, there were 114 new members and 21 international members elected.

Election to the National Academy of Engineering is among the highest professional distinctions accorded to an engineer. Academy membership honors those who have made outstanding contributions to "engineering research, practice, or education, including, where appropriate, significant contributions to the engineering literature" and to "the pioneering of new and developing fields of technology, making major advancements in traditional fields of engineering, or developing/implementing innovative approaches to engineering education."

Individuals in the newly elected class will be formally inducted during the NAE’s annual meeting on September 29, 2024. Learn more about the National Academy of Engineering at https://www.nae.edu/.

Sandians Help Develop New Energy Storage Standards Through ESSB Committee

From January 30 – February 2, 2024, Sandia staff participated in the 2024 IEEE Energy Storage and Stationary Battery (ESSB) committee’s winter general meeting. The meeting was held in San Diego, CA, co-located with the IEEE EESAT conference. These ESSB biannual meetings cover committee-level administrative and planning activities, plus additional breakout meetings for individual standards working groups sponsored by the ESSB. See the winter meeting agenda here.

Sandia staff and contractors who participated include:

  • Babu Chalamala, past ESSB Chair
  • Waylon Clark, P3434 Working Group Chair
  • David Rosewater, P2686 Working Group Chair
  • David Schoenwald, P2688 Working Group Chair
  • Tu Nguyen, P2688 Working Group Vice Chair
  • Tom Carpenter (contractor), ESSB Treasurer
  • Chris Searles (contractor), ESSB Awards Chair and past ESSB Chair
  • Charlie Vartanian (contractor), ESSB Energy Storage Collaboration Team Secretary

The ESSB Committee plays a crucial industry role by both maintaining the IEEE’s existing set of “traditional” technical standards for stationary batteries, while also developing new standards for emerging storage technologies and the integration of storage technologies into energy storage systems. The active expansion of standards under ESSB addresses a strategic gap that the DOE OE ES R&D program has identified as a barrier to stationary storage adoption, specifically lack of standards. Sandia staff lead several of the newer ESSB standards projects, including a new draft IEEE recommended practice for Battery Management Systems (BMS, IEEE project P2686) and new draft IEEE recommended practice for Energy Storage Management Systems (ESMS, IEEE project P2688). The Summer 2024 ESSB general meeting will be held this July in Richland, Washington. Additional meeting information will be posted at IEEE PES Energy Storage and Stationary Battery Committee (ESSB).

Sandians Assist in Revising IEEE 1547.4-2011 Standard

On January 23, 2024, Sandia staff participated in the second meeting of the P1547.4 Working Group (WG). The P1547.4 WG, chaired by Michael Ropp of Sandia National Laboratories, is revising the IEEE Guide 1547.4-2011 “Guide for Design, Operation, Integration, and Interoperability of Intentional Electric Systems Islands.” This guide supplements the IEEE Standard 1547 for interconnection and interoperability of Distributed Energy Resources. Of particular relevance to the Energy Storage (ES) program is promoting the beneficial role and function of ES in islanded power systems, e.g. microgrids. Additionally, the revised 1547.4 could include guidance on using ES assets within a microgrid to regulate frequency, while islanded from a centrally dispatched networked power system. Charlie Vartanian (contractor for Sandia) also assisted with Working Group process administration.

Sandians Published in the Journal of The Electrochemical Society

Reed Wittman and Yuliya Preger, members of the Safety & Reliability team in the Sandia Energy Storage program recently published the first part of a two-part study on the materials degradation of Li-ion batteries during long-term cycling in the Journal of the Electrochemical Society. The paper titled “Characterization of Cycle-Aged Commercial NMC and NCA Lithium-ion Cells: I. Temperature-Dependent Degradation” focuses on the impact of temperature on the materials of NMC and NCA 18650 cells cycled at different temperatures. For the whole study, the authors produced over 150 data sets, making this the largest characterization study of Li-ion batteries that have gone through systematic cycling to date in the open literature. The article also provides detailed analysis of how these batteries degrade, and how these findings can be used to improve their performance and utilization in the future. The raw data underlying this analysis is available at https://www.sandia.gov/energystoragesafety/rd-data-repository/.
