Requirements Methods used in IntelliGrid that can be applied to any project

• Carry a wide view of the application: How the deployed system be used by a variety of stakeholders and applications.

• Wear several “hats” in the process:– End User - Applications– Systems Administration – Network Management– Cyber Security

• Use a “template” approach or other tool

• Capture Stakeholder input from Multiple Perspectives– Stakeholder Documents– Stakeholder interviews


Develop Requirements for All Three Major Categories Together

• Applications: – System must support the requirements coming from

power engineering needs

• Systems and Network Management:– Installed Communications Networks and Intelligent

Equipment Must be able to be maintained

• Security:– System must include adherence to security policies and

include system “hardening” as well as managing residual risk

IntelliGrid AMR Functions

• Meter Data Management Agent (MDMA) reads meters with handheld/mobile technologies

• MDMA reads industrial and/or commercial meters with fixed AMR technology

• MDMA reads residential meters with fixed AMR technology

• MDMA provides individual and aggregated meter readings to market settlements, DisCos, and/or TransCos

• MDMA or DisCo provides individual energy usage and billing to customers

• Prepay metering

• Non-electric metering -- subcontracted submetering for non-electric utilities --Note: focus on aspects of shared infrastructure and not the actual metering

• Sub-metering -- customer bill dis-aggregation and rental space allocations

• Non-intrusive load monitoring -- deducing load contributions by monitoring aggregate consumption changes

• Outage isolation


Example Use Case: One Way AMR - New Meter1. Narrative

• An expert describes in text form how a given future power engineering function is performed including the high level business and technical context.

• Narrative focuses on the necessary distributed computing needs/requirements of the function

• Includes diagrams that can be understood by the stakeholder communities..power engineers, rate administrators etc.

The purpose of the One-Way Fixed Network AMR Function is to collect meter information from customer sites, including monthly meter readings, on-demand meter readings, tamper detection, soft connects and disconnects (on-demand meter readings), and outage detection. These systems can be used for all types of customers.

The one-way fixed network AMR system must first be installed. These AMR systems are “in-bound” vendor-proprietary networks using different media, such as telephone, power line carrier, satellite pager systems, wireless cellular systems, and possibly the Internet. Different vendors provide different functionalities, which are constantly changing as technologies and equipment prices change. Some fixed network AMR systems are basically one-way, but can provide limited two-way functionality, possibly through low bandwidth signals or Internet Web pages providing information back to the customer. (For IntelliGrid Architecture project, the internal functioning of these vendor-proprietary systems is out of scope: interested readers are directed to the Web Sites of the various AMR vendors.)


Example Use Case: New Meter Installation2. Identify the Actors

• From the narrative, determine the key players, or Actors (devices, people, systems).

• Name the actor and describe what it does in tabular form


Example Use Case: New Meter Installation3. Identify the Information

• What information do the actors exchange?• Focus on exchanges that may cause communications problems.


Example Use Case: One Way AMR4. Define Steps

• What happens, and in what order? Steps are numbered.• References the actors and the information• Formal, rigorous, machine-readable description of the narrative


Example Use Case: One Way AMR5. Identify Architectural Issues

• For each step, mark multiple-choice X’s regarding configuration, quality of service, security and data management

• A machine-readable rating of qualitative values.

IEC 62351 - Security• A set of specifications for data and communication security. The following parts

are intended to be part of IEC 62351:– IEC 62351-1: Data and Communication Security – Introduction and Overview– IEC 62351-2: Data and Communication Security – Glossary of Terms– IEC 62351-3: Communication Network and System Security – Profiles Including TCP/IP.

These security standards cover those profiles used by ICCP, IEC 60870-5 Part 104, DNP 3.0 over TCP/IP, and IEC 61850 over TCP/IP.

– IEC 62351-4: Communication Network and System Security – Profiles Including MMS. These security standards cover those profiles used by ICCP and IEC 61850.

– IEC 62351-5: Data and Communication Security – Security for IEC 60870-5 and Derivatives (i.e. DNP 3.0). These security standards cover both serial and networked profiles used by IEC 60870-5 and DNP.

– IEC 62351-6: Data and Communication Security – Security for IEC 61850 Profiles. These security standards cover those profiles in IEC 61850-7-2 that are not based on TCP/IP –GOOSE, GSSE, and SMV.

– IEC 62351-7: Data and Communication Security – Management Information Base (MIB) Requirements for End-to-End Network Management. These security standards define Management Information Base (MIBs) that are specific for the power industry, to handle network and system management through SNMP-based capabilities.


Information Industry Technologies

• The ongoing development of the Internet has been a substantial source of advancement in networking and distributed systems development.

• It is important to distinguish, however, Internet-based technologies, such as TCP/IP and XML, from the use of the Internet itself.

• Using the existing Internet is an independent decision that should be consistent with system management and security policies from those organizations agreeing to use it.

• Internet technologies, and those emerging from the next generation Internet development work, can be used independently of existing Internet architecture.

• Internet-based technologies have become prevalent throughout most industries, and many, such as TCP/IP and HTML, are used almost to the exclusion of other equivalent technologies.

• Increasingly, web services are being seen as the wave of the future.


Key Observations

• Power engineers must now know enough about information technology to get beyond the dangerous stage – they must know enough to be effective

• Power engineering is already a relatively small subset of electrical engineering

• Power engineers who are interested in, let alone like, understand, or are enthralled by information technology are much harder to come buy

• This issue could be a major impediment to moving the electric power industry into the 21st century
