    Products vs. Platforms

    Product

    Examples: appliances, automobiles, GPS

    Thought-of as a complete package: software, hardware, all in one

    All from one vendor

    Lifetime needs known at the time of purchase

    Not upgradeable, or only by the original vendor

    Platform

    Examples: personal computers, smart phones

    Thought-of as a supporting foundation for applications, a starting point

    Applications can come from many sources

    New needs are determined throughout the service life

    Owner/user upgradeable

    Open Apps a Natural EvolutionTelevision Example

    Analog Digital Platform

    No one can make changes

    Manufacturer can make changes

    User can make

    Why Make Smart Grid Devices Platforms?

    Advancements in microprocessor and memory technology have made it practical

    Advancements in connectedness and 2-way communication technology have made it achievable

    Need for cohesive & consistent behavior across mixed devices and systems

    Upgrading functionality over the service life (utility equipment is long-life)

    Enabling new system-level functionality

    Fostering innovation

    Smart Meter Open ApplicationsProject

    Meeting weekly to develop the open platform specification for smart meters

    Other utilities and meter/AMI vendors encouraged to join the discussion

    Working towards a demonstration

    Smart Meter Open ApplicationsExample Use Cases

    Use Case Rationale for IncludingPushed Energy Consumption Reading for Billing Purposes Universal, baseline meter application

    Power Quality Monitoring Selectively deployedOutage Notification Unifying behaviors across devicesDemand Limiting Application International use case, uncommonOver-Temperature Detection Application Recently added application

    Theft Detection at the Distribution Transformer Level Multi-device, system-level application

    Supervision of Motor Response to Voltage Sags

    Innovation, New logic, a future addition.

    Three Core API Sets

    APIs are standard high-level interfaces for apps Key component of the open platform effort

    API Sets:1. Metrology (i.e. reading data from meter: kWh, etc)2. Communications3. Control (power on/off, reset)

    Common Information Model (CIM) for Metrology API Rationale:

    Not reinventing the wheel Utility enterprise systems speak this language Minimizes unnecessary translation

    Enterprise Application

    Demonstrations Using the Java Platform

    Java selected for these demos because:

    Maturity/availability

    Large developer/third-party software ecosystems

    Existing libraries

    Application models, threading models, file systems

    Complex networking/communications/security libraries

    Open source implementations

    Raspberry Pi as Development Platform

    Raspberry Pi

    Meter Platform

  • 14 2014 Electric Power Research Institute, Inc. All rights reserved.

    Example: Comm Node as an Open App Platform

    Duke Energy Initiative

    Coalition of companies devices, meters, controls, communications

    Demonstrated at DistribuTech 2014

    Phase 2 in process

    Next Steps

    Field Demonstrations

    multiple products

    independently developed apps

    Standardization

    Certification and Compliance

    for platforms

    for apps

    Launch of work on other Smart Grid Devices

    RFPs based on standardization and certification
