Goals of this presentation

• Introduce Smart Grid
• Interoperability within Utility

departments.

• System of systems approach
• Model framework and sample

design

Utilities Operate in Departments

• Transmission and Distribution
• Power Production
• Technology (Includes IT)
• Communications
• Human Resources
• Finance
• Commercial
• Regulatory, Legal, Planning and Government Relations

How they work together

IT as a bridge group

• Interfaces with EVERY department
• Understands the cybersecurity risk.

Birth of Smart Grid

• First official definition in 2007
• Integrated network

communications

IT and OT

Information Technology

• Short support life (3-5yrs)
• Business oriented
• Constantly changing

environment

• Commercial Off the shelf

Operations Technology

• Long support life (40yrs+)
• Operation/Industry oriented
• Typically minimal changes after

commissioning

• Custom Hardware and software

based on standards.

Time is critical in control

• A cycle is 16ms
• Ping to google is 19ms
• Network latency is not always

predictable.

Make the problem smaller

Divide and Conquer First Principles

I have a plan

• Think interoperability
• Break the system into a bunch of

smaller systems

• Add predictability
• Standardize methods to make

recipes for reports.

What are the nodes in a utility

Connecting to the Enterprise

• Geography changes the design

method

• Good vs poor communication
• Communication latency

Standardize Everything

• Create standard scaffolds to

build upon

• Standardize naming and

description

• Think recipe book not a single

recipe

• Standardize on process not part

number

Good Communication Infrastructure

• RTAC and firewall to

communicate to VTScada Server

• Local HMI powered from the

SEL-3530 RTAC

• All local assets connected to

RTAC via various protocols and mediums

Weak Communication Infrastructure

• Local VTScada application

replaces HMI.

• Synced with VTScada application

at the data center

• Communications design based
• n design requirements
• Some relayed through RTAC
• Some parallel with RTAC
• SCADA server connected to the

both RTAC and firewall.

What did we cover

• First, thanks to Trihedral for

having me and Dave Spencer for sending the invitation.

What we didn’t cover

• The start of the discussion
• Smart Grid is an evolution in

thinking, not a step change

• Start small and start building
