The Smart Grid
- Modernization of the existing electrical system
○
A vast network of computerized meters and infrastructure
- Benefits for consumers
○
More control over their energy use/utility costs ○ Improved reliability, outage response, and service convenience
- Benefits for industries
○ Time-of-use pricing (e.g. charging higher fees during peak hours) ○ Better capacity and usage planning ○ More malleable energy markets

SLIDE 9
Meter Manipulation
- Customer frauds
○ Fabricated meter readings (like meter inversion)
- False indictment

SLIDE 10
Network
- Bidirectional communications
- Targets include meters and infrastructure
○ Meter bots ○ DDoS
- Communication protocols

SLIDE 11
Shared Information
- Energy usage patterns
- Google PowerMeter Service
○ Unclear laws, regulations, and guidelines

Current State of Smart Grids (Ameren)
- Upgrades in progress
○ “By 2019, more than half (62%) of electric customers will receive [smart] meters”
- Daily usage reports and time-of-use (real-time) pricing option available
- Still rely on meter reading in-person

SLIDE 13
Future of Smart Grids
- Long-term vision
○ Global energy management ○ Home area networks that can control smart appliances
13
SLIDE 14
What Now
- Laws, regulations, consumer protections
- More studies to mitigate the concerns
○ Approaches suitable for critical systems
- Plan for failure
○ Resilience ○ Reliability

Discussion
- Does the smart grid increase resilience to system failures and cyber
physical attacks?
- The smart grid is going to happen. But what about the long-term goals of
the smart grid? Are they realistic? Should we prepare defense strategies? Or do we need more realistic goals?
- Any other security and privacy concerns?
