This is a continuation of the review of Preliminary Discussion Draft: NIST Framework and Roadmap for Smart Grid Interoperability Standards, Release 3.0.
Chapter 4: Standards Identified for Implementation (pp. 62–120)
This is the chapter I am most interested in. Table 4-1 (page 70) contains a set of standards, specifications, and guidelines that NIST deems important for smart grid interoperability. A number of entries in Table 4-1 are a set of accepted standard technologies for smart grid. The number of entries has increased from 34 to 68 since release 2.0. In the release 2.0, there was a table called Table 4-2, which listed for additional standards, specifications, profiles, requirements, guidelines, and reports for further review. But it is no longer there.
One thing I noticed is that a set of standards of the Society of Automotive Engineers (SAE)‘s standards are missing in Table 4-1 in this draft, while they were in Table 4-1 (page 70) of the release 2.0. They are: SAEJ1772, SAE J2836/1, and SAE J2847/1. I thought that if something is included in Table 4-1 once, it is not removed from the table. By the way, in the current CoS, all of these are listed, plus SAE J2836/2-3 and SAE J2847/2-3.
Two things I found are: the standard selection criteria described oin pages 65-66 are noteworthy and in the new table, more entries from IEC and IEEE are added but I did not see any more typical IT technologies added.
Chapter 5: Architectural Framework (pp. 121–148)
Along with Table 4-1, the conceptual model as shown below is very interesting to me as an ICT guy. This figure has not changed since the release 2.0.
Chapter 6: Cybersecurity Strategy (pp. 149–157)
Some documents are noteworthy:
- Guide for Assessing the High-Level Security Requirements in NISTIR 7628, Guidelines for Smart Grid Cyber Security (Assessment Guide)
- NISTIR 7628 User’s Guide, which facilitates use of the previously published National Institute of Standards and Technology Interagency Report (NISTIR) 7628, Guidelines for Smart Grid Cyber Security
- Electricity Subsector Cybersecurity Risk Management Process, SGCC in collaboration with the U.S. Department of Energy
Chapter 7: Framework for Smart Grid Interoperability Testing and Certification (pp. 158– 171)
New material reviews the key components and deliverables from the testing and certification framework development activities. The emerging implementation phase projects and activities since release 2.0 are then discussed, as well as views on the longer term implementation needs and challenges in maintaining a robust testing and certification approach for interoperable smart grid systems and devices.
Chapter 8: Cross-Cutting and Future Issues
Some discussion subject was of electromagnetic compatibility. I am not sure how ICT can help this yet.
