June 8, 2010


Openhan srs v1 95

OpenHAN SRS v1.95

  • Introduction

    • OpenHAN area of focus within the NIST conceptual model


Openhan srs v1 951

OpenHAN SRS v1.95

1. Introduction, continued

Purpose

Define the system requirements for an open standard Home Area Network system

Promote open standards-based HANs that are interoperable

Provides the vendor community with a common set of principles and requirements around which to build products

Ensures reliable and sustainable HAN platforms

Supports various energy policies in a variety of states, provinces, and countries

Empower consumers to manage their electricity consumption by giving them the information and control they need to make decisions on their energy use and to effectively control their energy consumption

OpenHAN SRS v1.95

1. Introduction, continued

Purpose, continued

The audiences for the OpenHAN SRS are:

Utilities considering deploying AMI systems that interact with HANs

Vendors that make AMI systems for Utilities that interact with HANs

Vendors that make consumer products (e.g. PCT,EMS, load control switches, in-home displays, smart appliances, PEV, DER, etc.)

Service Providers developing smart grid enabled programs for consumers (e.g. demand response, energy management, pre-pay, PEV programs, distributed energy resources , etc.)

Policy makers looking to understand how Utility AMI deployments benefit consumers

Industry alliances and standards organizations

NIST Smart Grid Interoperability Panel (SGIP) activities (e.g. Smart Grid Architectural Committee (SGAC), Cyber Security Working Group (CSWG), Smart Grid Testing and Certification Committee (SGTCC), etc.)

OpenHAN SRS v1.95

1. Introduction, continued

Scope, Definitions, Other Considerations and References

Provides platform-independent requirements for HAN devices regardless of device ownership

Not limited to the residential premise, although the residential consumer has the most to gain from the OpenHAN SRS

Provides an overview of the regulatory, political, and legislative environment that influenced the development of the OpenHAN SRS

Security in the HAN Environment

Two-way HAN communication is a new technology being introduced to the electric power grid

The proper security measures need to be in place to reduce the risk of intrusion, eavesdropping, and the transmittal unwanted content

OpenHAN TF in conjunction with SG Security WG evaluated the potential impact of a security compromise to the HAN

OpenHAN TF reviewed the NISTIR 7628 recommended security requirements for the HAN interface to identify any gaps

Openhan srs v1 954

OpenHAN SRS v1.95

2. Overall Description

Guiding Principles

Capabilities

Secure Two-way Communication Between HAN Devices and Service Provider(s)

Supports load control integration

The AMI meter provides the HAN with direct access to Consumer-specific usage data

Provides a growth platform for future products which leverage the HAN and meter data

Supports three types of messaging: Public, Consumer-Specific, and Control

Supports end-use metering and other utility meters

Supports distributed energy resources

Assumptions

Consumer owns the HAN

HAN devices present additional security considerations

The HAN is enabled by open and interoperable standards

Openhan srs v1 955

OpenHAN SRS v1.95

2. Overall Description, continued

Architectural Considerations

OpenHAN applies from the edge of the AMI System, where the Energy Services Interface (ESI) resides, to all relevant HAN Devices in the home

Energy Services Interface (ESI)

An interface which enables communication between authorized parties and HAN devices that are registered to it

There may be more than one ESI in the premise

Utility ESI – provides interface between the Utility AMI network and HAN devices

Other ESI – provides interface between other communication media (e.g. internet, cell phone, EMS, etc.) and HAN devices registered to it

Openhan srs v1 956

OpenHAN SRS v1.95

2. Overall Description, continued

Architectural Considerations, continued

Commissioning, Registration, Enrollment

Commissioning is the process by which a HAN device obtains access to a specific physical network and allows the device to be discovered on that network

Registration is the process by which a Commissioned HAN device is authorized to communicate on a logical network by exchanging security credentials with an ESI

Enrollment is the process by which a Consumer enrolls a HAN device in a Service Provider program (e.g. demand response, energy management, PEV program, etc.)

OpenHAN SRS v1.95

2. Overall Description, continued

Architectural Considerations, continued

OpenHAN SRS is agnostic to device ownership

Some HAN devices may reside on a 3rd party network and the Utility ESI

OpenHAN SRS is agnostic to electric market structure and may be used in integrated utility markets as well as consumer choice electric markets

There may be multiple communication paths into the HAN (e.g. Utility AMI, internet, cell phone network, EMS, etc.)

OpenHAN SRS addresses the following special applications

PEV including the Energy Vehicle Supply Equipment (EVSE) and End-use Measurement Device (EUMD)

Energy Management System (EMS)

Distributed Energy Resources (DER)

3. OpenHAN System Requirements

  • Requirements Mapping to Logical Devices

    • Provides guidance to Service Providers and vendors

    • For reference only and should not limit the needs of Service Providers or vender innovation

    • Mapping Categories

      • BC or Basic Commissioning – Minimum requirement for the Commissioning process. These requirements are mandatory and must be included to support the process of Commissioning a HAN device on the HAN.

      • BC or Basic Registration - Minimum requirement for the Registration process. These requirements are mandatory and must be included to support the process of Registering a HAN device on the ESI.

      • BF or Basic Functionality – Minimum requirement that the OpenHAN TF recommends is needed to support the basic functionality of the logical HAN device.

      • O or Optional – An optional requirement that may be included to support a Service Provider program or allow a vendor to differentiate their product.

      • NA or Not Applicable - This requirement is not applicable to this logical HAN Device.

3. OpenHAN System Requirements, continued

Requirements Framework and Assumptions

Application Requirements

Control applications respond to control signals

Measurement and Monitor applications provide internal data and status

Processing applications consume, process, and act on external and internal data

Human Machine Interface (HMI) provides Consumers a means to provide input into an application or to view information from an application

Communication Requirements

Commissioning is the network process of adding a HAN device on the HAN to allow the device to communicate with other devices and involves network scanning, selection, admission, and configuration

Control of a node involving self-organization, path selection, mitigation

13


Openhan srs v1 9511

OpenHAN SRS v1.95

3. OpenHAN System Requirements, continued

Security Requirements

Access Controls and Confidentiality address data protection for data-at-rest and data-in-transit

Registration is the network process to authenticate and authorize HAN device participation with an ESI and includes initialization, authentication, correlation, authorization, and de-register

Enrollment is the process by which a Consumer enrolls a HAN device in a Service Provider’s program (e.g. demand response, energy management, pre-pay, PEV programs, distributed generation, pricing, messaging, etc.) and gives certain rights to the Service Provider to communicate with their HAN device

Integrity preserves the HAN operating environment through resistance and recovery

Accountability will allow for monitoring malicious activities through audit and non-repudiation

14

3. OpenHAN System Requirements, continued

Performance Requirements ensure applications or other factors do not limit the performance of the system, which is dependent upon availability, reliability, maintainability, scalability, upgradeability, quality and latency

Operations, Maintenance, and Logistics Requirements

Manufacturing and Distribution - Vendor’s pre-installation activities including pre-Commissioning settings, application configuration, labeling, support for multiple distribution channels

Installation – Documentation for the physical placement of the device and support systems

Manage, Maintain – ensure HAN device diagnostic, management and trouble shooting capabilities including alarming, logging, testing, device reset, and monitoring
