• Optimizes resources and time

• Avoids proprietary vendor lock-in

• Helps build technology roadmaps

• Simplifies decision making

SGIP Reduces Risks and Costs

SGIP is a collaborative, transparent, and trusted forum to share standards

information and practical, hands-on knowledge about deployments from

industry experts.

SGTCC Overview

• Developing and Accelerating Smart Grid testing programs is a major focus for the SGIP Testing and Certification Committee (SGTCC)– Limited number of existing industry test programs

• SGTCC has developed a framework and processes to facilitate program development

• SGTCC has provided guidance to test programs in development– OpenADR, Green Button are examples





6

SGTCC Overview

• Testing, Interoperability and Certification are not always well understood by stakeholders

• SGTCC Outreach goals include:– Building awareness of testing and the value that test

programs bring to technology evaluation

– Encouraging utilities/purchasers to integrate testing and certification metrics in their procurement processes

– Demonstrating case studies highlighting industry success in implementing testing programs

SMUD’s Need for Testing &

Certification

• Business drivers for HAN testing

• Cultural shift from “responsibility stops at the meter”

• Needed internal testing processes, expertise quickly

• Utility-program deployment model



Powering forward. Together.

HAN Device Testing Model



15

HAN Device Testing

• SMUD has contracted with NTS for ZigBee SEP certification, SSN compatibility, and basic Functional testing of HAN devices– leverage their standards expertise and tools– provides only bench-top testing to pre-qualify

devices for SMUD’s lab– consults on design of SMUD-specific test cases– provides support to SMUD on their configurable test

harness

• SMUD has onsite HAN testing lab for end-to-end functional testing over AMI (ZigBee) and broadband (AutoDR) from DRMS, and Customer experience testing. Prerequisite for the HAN lab:– HAN devices must be SEP certified– HAN devices must have been tested by NTS

Retail Deployment Model



18

HAN Deployment Model

• HAN gateway demarcation point

• Cyber Security firewall

• Dual communications path

• More customer choice

• Limits Utility support to one device (gateway)





19

Industry Testing & Certification

Program• SEP and OpenADR standards• Clear Interoperability guidelines • Interoperability Testing and Certification Authorities

(ITCAs)– Test programs available from multiple test houses– Test Tools

• SGIP & SGTCC– SGIP Catalog of Standards– NIST Framework for SG Interoperability Standards ver. 3 – Interoperability Process Reference Manual (IPRM ver. 2)– SGTCC “Catalog of Test Programs”





20

Key Takeaways

• Leverage existing standards and testing resources (SGTCC)

• Procurement considerations for testing and certification

• Utilize external HAN testing lab for their tools & expertise

• Retail deployment model should utilize a HAN gateway with multiple communication paths to mitigate communication issues

Understanding Interoperability



What is it?BenefitsInteroperability Maturity



25

Smart Grid and Interoperability

• Smart Grid requires sophisticated two-way communications between actors

• Can be built by traditional (and costly) unique solutions– Doesn’t scale well

• Or…by adopting interoperability principles and standards– Scaling and flexibility

– Accelerates change






26

Interoperability Progression

A: No standard exists, requires completely custom integration

Party A Party B

D: Plug and Play and standard defined

C: Interfaces use a common model

(standard)

B: Interfaces can be transformed and/or

mapped

GridWise Architecture Council “GridWise Interoperability Context-Setting Framework V1.1,” March 2008






27

What is Interoperability?

• A shared understanding of the information exchanged

• An agreed expectation for the response to the information exchange

• A requisite quality of service: reliability, fidelity, and security

System-System Interoperability

Interoperation = integration = communication

Method A: Custom bilateral: unique interface between each pair of systems

– Expensive to build, maintain and modify

– Vendor lock-in

Vendor 1Vendor 2

Vendor 4Vendor 3






30



Method B: ESB or Universal Adapter – convert to one format

– Less expensive to build, maintain and modify

– Proprietary adapter format

– Easier substitution

Vendor 1Vendor 2

Vendor 4Vendor 3






31



Method C: Open Communications Standard

– Each vendor implements standard communication protocol

– Easiest to implement (plug and play?)

– Easiest product substitution

Standards






34

Standards

• A technical specification, usually produced by a Standards Development (Setting) Organization (SDO/SSO)

– Recognized standards bodies (ISO, IEC, IEEE, ANSI, etc.)

– Trade alliances (ZigBee, Wi-Fi, OpenADR, MultiSpeak)

• Enables wide adoption of technology by multiple competing and complimentary vendors






36

Benefits of Standards – NIST

Framework Draft 3.0• Standards reduce “stranded assets” by ensuring compatibility with

evolving technologies• Innovation is catalyzed – reduce investment uncertainty in new

products and increase market opportunities• Consumer choice of competing products based on standards is

enhanced• Costs are reduced (product, acquisition, integration and

maintenance) with economies of scale• Utilities can adopt best practices based on using standards –

experience is portable• Global markets are available, increasing vendor competition,

lowering costs for utilities and customers• Cyber security and privacy better addressed in standardization than

custom systemsNIST Special Publication 1108R3, Preliminary Discussion Draft, “NIST Framework and Roadmap for Smart Grid Interoperability Standards, Release 3.0”, February 2014, http://www.nist.gov/smartgrid/upload/NISTDraftFrameworkOct_2013.pdf

Standards-Based Products



Achieving Interoperable ProductsWhy do interoperability problems happen?How are they avoided?How to create an eco-system of interoperable products from a standard



38

Why do Interoperability Problems Occur?

Vendor 1 Tests

Interop problem discovered during deployment. Time and schedule impact.

Sends SIMPLE event values as 0.0, 1.0, 2.0, 3.0

Sends SIMPLE event values as 0, 1, 2, 3

Vendor 2 Tests

No standard tests or certification






39

Vendor 1 Tests

Why do Interoperability Problems Exist?

SIMPLE event values sent in both representations “1” and “1.0”

Vendor implementation expecting integer (0 1, 2, 3) representation of SIMPLE event signals

Conformance problem discovered during development and fixed. Interop problem eliminated. Passes certification.

With standard tests and certification

The SGIP TCC and Interoperable

Products

• Focused on improving quality of Smart Grid Interoperability test and certification programs

• Guidelines to good program design

• Working with emerging ITCAs

• Assessment of ITCA programs





42

Key Takeaways

• Interoperability is 1) shared understanding of the information exchanged and 2) agreed expectation for the response to the information exchange

• Standards enable wide adoption of technology by multiple competing and complimentary vendors –– Accelerates change; increases flexibility; reduces costs and

schedules

• Achieving interoperable, standards-based systems and products requires multiple steps – but can be achieved

• There are good resources available from SGTCC






43

QUESTIONS?





44

Closing

• Education and Outreach highlighting testing benefits are an SGTCC initiative– SMUD case study is an excellent example to encourage the

use of effective industry test programs• Takeaways

– Involvement in SGTCC and industry alliances provide a means to define, develop and implement test programs that benefit both utilities and their vendors

– Requiring participation in industry test programs within the purchasing process can speed technology adoption and reduce cost by minimizing duplicative testing activities

• SGTCC is planning additional webinars/seminars in 2H2014 to further encourage test program development and adoption
