UCAIug HAN SRS v2.0Purpose

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

Promote open standards-based HANs that are interoperable Provide the vendor community with a common set of principles

and requirements around which to build products Ensure reliable and sustainable HAN platforms Support 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

7

UCAIug HAN SRS v2.0The audiences for the HAN 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. programmable communicating

thermostats, energy management systems, load control switches, in-home displays, smart appliances, Plug-in Electric Vehicles (PEV), distributed energy resources (DER), etc.)

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

Policy makers looking to understand how Utility AMI deployments that interact with HANs benefit and impact 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.)

UCAIug HAN SRS v2.0Guiding Principles

Capabilities1. Supports Two-way Communication Between HAN Devices and Service

Providers2. Supports load control integration3. The AMI meter provides the HAN with direct access to Consumer-

specific usage data4. Provides a growth platform for future products which leverage the HAN

and meter data5. Supports three types of messaging: Public Information, Consumer-

Specific Information, and Control Signals6. Supports end-use metering and other utility meters7. Supports distributed energy resources

Assumptions8. Consumer owns the HAN9. HAN devices present additional security considerations10. The HAN is enabled by open and interoperable standards

UCAIug HAN SRS v2.0

Architectural Considerations HAN SRS applies from the edge of the AMI System, where the

Energy Services Interface (ESI) resides, to all relevant HAN Devices in the premises

Energy Services Interface (ESI)o An interface which enables communication between authorized parties

and HAN devices that are registered to ito There may be more than one ESI in the premise (e.g. Utility ESI, 3rd

party ESI)o Utility ESI – provides interface between the Utility AMI network and HAN

devices, including the AMI metero Other ESI – provides interface between other communication media

(e.g. internet, cell phone, EMS, etc.) and HAN devices registered to it

10

Architectural Considerations, continued Commissioning, Registration, Enrollment

o 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

o 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

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

Architectural Considerations, continued

HAN SRS is agnostic to device ownership Some HAN devices may reside on more than one ESI HAN 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.)

HAN SRS addresses the following special applicationso Plug-in-Electric Vehicle (PEV) o Energy Management System (EMS)o Distributed Energy Resources (DER)

HAN System Requirements 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

HAN 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

HAN 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
