Characteristics of
Renewable Energy in Smart Grids
• Generation Types:
–
–
–
–
–
–
–
Traditional Generation
Wind
Solar (various technologies)
Hydro
Biomass
Geothermal
Electric vehicle
• Transmission and Distribution 2way power flow
• Active and Fluctuating
Operations
• 2-way (or more)
communications
• High Variability and localized
solutions
For Utilities – Opportunities with
Renewables in Smart Grid
•
•
•
•
•
Regional planning & coordination
Build off existing infrastructure
Increased reliability and security
Help “Self healing”
With “real time” decision making,
provide local alternative generation
• Integrate different generators &
generator types
For Utilities - Challenges
with Renewables in Smart Grid
• Lack of customer understanding
• Utilities need to change thinking to react
more quickly
• Variability & differential generation
patterns
• Lack of standards and interoperability
• Financial models for cost recovery must
change
• Security of grid
• No “one size fits all” solutions

Guiding Principles
• Customer Empowerment
• Improve Reliability
• Focus on Value – Shareholders,
Customers
• Increase Safety
• Integrate with energy
conservation & DSM programs
• Explore regional opportunities
• Leverage – equipment,
information, programs,
enterprise systems
• Recover all costs
• Support local green energy &
economic development goals
• Maximize security of grid and
customer information

Lessons Learned
•
•
•
•
•
•
•
•
•
Price of failure to adapt very high
Everything changing very quickly
Difficulty of technology integration (including Renewables)
Technology obsolescence is a problem (including Renewables)
Customers very different, with varied expectations
SmartGrid design and function will vary by utility and region
Cost / Benefit ratio should be positive
Siting challenges
Barriers to scale

•Renewables Picture:
•Currently Coal & Natural Gas
•Transmission Constraints
•Important wind resources
•Good solar resources
•Pilot Elements:
•Advanced Metering Systems
•Intelligent Grid
•Vision: “CNP seeks to enable the Texas electricity market to extract the full
functionality of the Smart Grid by supporting individual management of
electricity consumption, fostering adoption of market-driven programs and
achieving maximum operational readiness and efficiency.”

Friedrichshafen, Germany
• T-Systems:
– Provides IT and communication services, dynamic services,
energy services, cloud-based services – largest German telecom
company
– Energy efforts started with small metering solution for German
market, focus on privacy and security
• Renewables Picture:
– Germany well-known for focus on variety of distributed renewable energy
generation
– PV, electric cars, wind, solar thermal, biomass all in place
Friedrichshafen Summary
• Cooperative effort
• “Laboratory” with focus on
implementation
• Smart metering, smart grid, and general
smart technology services
• Multi-utility, sub-metering, multiple
standards in smart metering platform
• Small smart grid applications
– Demand response, power plant requirements,
economics research, market value research
Friedrichshafen Findings
• Communication is key with different types of
buildings & users, and generators
• Architecture which brings together different
meters is most useful
• Transformative technologies and methods
• Data privacy and data security critical
• Many common solutions would not meet
security requirements of telecom industry
• In Germany, change from yearly billing
required
• Rapid, complete roll-out most cost effective
Community scale smart grid in Japan
• Grid severely supply limited
• Acceleration of Smart Grid adoption
may be good alternative for future
• Potential Smart Grid elements:
– Accelerate adoption of technologies and
grid
– Smart meter options needed
– Mechanism needed for market signals –
price and command signals
Impacts from the Disaster
• After the earthquake and tsunami, surviving fossil fuel power
plants not able to handle load left by Fukushima closure
– Substation breakers were only tools available to keep grid in balance,
so had system of rolling blackouts
• Current actions:
– Recommissioning old plants
– Importing gas turbines
– Running all at full capacity
Kuzumaki Prefecture
• Local Smart Grid – Kuzumaki
– 8,000 people, 50 miles from
coast
– Power out for 1 day (connected
to grid)
– Started program 10 years ago

Lessons from Kuzumaki
• Intermittent
renewables
work in system
• Price and
control signals
– Wind power at
night increases
– Cloud over sun
during day
• Small regions of
grid disconnect
temporarily and
keep operating
