1. OpenADR SRS Draft 1 Review
UCAIug OpenADR Taskforce
Face to Face Meeting
May 6th, 2010

2. OpenADR SRS Draft 1 Review
Objectives & Final Deliverables
System Requirements Specification
Per SG Systems SRS Guidelines
Main focus is Integration Components
Services Definition
Artifacts to define payload
XSD’s and Web Services

3. SRS Components Architecture Views (Components) Business (Draft 1)
Use Case Driven (largely by these)
Open ADR Functional Requirements and Use Case Document (OpenSG)
Requirements Specifications for Retail Standard DR Signals - for NIST PAP09
Defines Integration Requirements and Business Services
Data (Draft 2)
Technical requirements on how data the is modeled
Ensure Semantic Interoperability
Application & Technical (Draft 3)
Security
Service Patterns

4. Draft Review Objectives
Confirm Scope & Structure
Business Processes
Business Process Flow
Business Roles
Integration Services
Logical Components
Entities that exchange information to carry out the business processes and implement the use cases
List of Services
Start from sequence diagrams in Use Case Documents
Map to sequence diagrams with Logical Components as actors
Define scope and priority (SRS Section )

5. Business Process Flow Using Business Role

6. Business Process Flow Using Logical Components

7. Logical Components – Data Exchange

8. DR Controlling Entity Instantiates the EPRI REC-VEN Concept?*
REC: Resource Energy Controller
Can receive and respond to messages. Examples:
Report what resources are available
Can effect changes in end use load/energy supply
Determine when to send specific grid messages to resources it manages
VEN: Virtual End Node
Generic reference to a logical load entity/device
Can manage DERs from a DR perspective
* Concepts to enable advancement of Distributed Energy Resources: White Paper on DER, EPRI, Palo Alto, CA:

9. Valid Configurations Building on REC-VEN Recursive Properties
All configurations appear identical from Grid perspective
Results in scalable, flexible, simple model that enables many possibilities for unforseen future configurations

10. Example of Flexibility in Application of Concept
DR Controlling Entity
Can think of DR Controlling Entity as VEN-REC?

11. Integration Services Critical Deliverable to Begin Data Model
Review from SRS Section
Scope
Priority
Traceability
