Context: Better Situational Awareness and Automation

• Increasing Dependence on ICT, Computation and Communications.

• Increasing Complexity: System integration, increased complexity: call for new approaches to simplify the operation of complex infrastructure and make them more robust to attacks and interruptions.

• Centralization and Decentralization of Control: The vulnerabilities of centralized control seem to demand smaller, local system configurations. Resilience rely upon the ability to bridge top‐‐down and bottom‐up decision making in real time.

A “Sanitized” Example: Lack of awareness and inadvertent connection to the Internet• Power plant: 2‐ 250MW, gas fired turbine, combined cycle, 5 

years old, 2 operators, and typical multi‐screen layout:• “A: do you worry about cyber threats?• Operator: No, we are completely disconnected from the net.• A: That’s great! This is a peaking unit, how do you know how 

much power to make?• Operator: The office receives an order from the ISO, then 

sends it over to us. We get the message here on this screen.• A: Is that message coming in over the internet?• Operator: Yes, we can see all the ISO to company traffic. Oh, 

that’s not good, is it?”

Smart Grid Vulnerabilities• Cyber:

– Existing control systems were designed for use with proprietary,stand‐alone communications networks

– Numerous types of equipment and protocols are used

– More than 90% of successful cyber attacks take advantage of known vulnerabilities and misconfigured operating systems, servers, and network devices

– Possible effects of attacks:1) Loss of load2) Loss of information3) Economic loss4) Equipment damage

Observations• Cyber has “weakest link” issues• Cyber threats are dynamic, evolving quickly and often combined with lack of 

training and awareness (forgetting/ignoring the human in the equation). • Installing modern communications and control equipment (elements of the 

smart grid) can help, but security must be designed in from the start.

• No amount of technology will make up for the lack of the 3 Ps (Policy, Process, and Procedures).

• Protect the user from the network, and protect the network from the user: – Develop tools and methods to reduce complexity for deploying and

enforcing security policy.– Build in secure sensing, “defense in depth,” fast reconfiguration and self‐

healing into the infrastructure.

• Security by default – certify vendor products for cyber readiness• Security as a curriculum requirement.• Increased investment in the grid and in R&D is essential.

“Computers are incredibly fast, accurate, and stupid; humans are incredibly slow, inaccurate 

and brilliant; together they are powerful beyond imagination.”

I‐35W bridge• To improve the future and avoid a repetition of the past: 

• Sensors built in to the I‐35W bridge at less than 0.5% total cost by TLI alumni

Awareness, Costs and BenefitsAwareness:• ~68% of consumers in the U.S. don't know what "Smart Grid” is…

– what is the "Smart Grid“?– what are the range of new consumer‐centered services enabled by smart grids?– what are the smart grid’s potential to drive economic growth? 

Costs:• EPRI: $165 billion over 20 years ($8 to $10 billion per year). • Energy consulting firm Brattle Group: $1.5 trillion spread over 20 

years (~$75 billion per year) for an overhaul of the entire electricity infrastructure.

• My work, 1998‐present: $150 to $170 billion ($10 to $13 billion per year for 10 years or longer).

… Awareness, Costs and BenefitsSmart grid benefits:

– Increases efficiency by 5% ($20.4 billion in savings annually) 

– Reduces costs of outages by about $49 billion per year

– Reduces emissions by 12‐18%– Increases overall energy security, and can spur economic growth

• Our $14 trillion economy depends on reliable, disturbance‐free access to electricity.

“Only three things happen naturally in organizations:

friction, confusion and underperformance.Everything else requires leadership.”
