2. Consequence With Future Urbanization

3. Next Generation High-tech City (Predicted )
More skyscrapers will be introduced in commercial urbanization

4. Complex with high mobility communication system due to compact
urbanization is essential, which is indispensable part for high-tech city. Again
it has a great impact on daily personal as well as commercial phenomenon.

5. Future Electricity System
Urbanization, climate change and demographic change are forcing cities to make
their infrastructure more efficient in order to guarantee seamless integration of
renewable energies and stable grids and thus maintaining a high quality of life.
Energy Supply in High rise buildings

6. Smart House Energy supply Smart Lighting
Approximately 20 % of the global electrical
energy is consumed by lighting
applications, so it need to be considered.

7. Electric Vehicle Smart Building
EVs and PHEVs are expected to provide
large private and social benefits, in
particular in reducing oil use, GHG
emissions and pollutant emissions.

8. Development Needs for Smart Grid
 Smart Metering
 Demand response
 Reliability of power distribution
 Automatic maintenance and operation
 Remote control of appliances through the internet
 Expanded Building Automation Systems and Wireless Controls
 Boost the reliability and efficiency of renewable energy sources
 Underground cabling system to minimize the power system failure and
interruption
Renewable energies, efficient transmission and distribution and careful consumption
management are the key to ensuring a sustainable and environmentally friendly world growth.

9. Threats for the Smart Grid
 Capacity of electrical system to feed the
increasing demand.
 Reliability of electricity supply- Safe
operation, Impact of unavoidable faults,
immediate restoration of full performance.
Distribution grids are pending from a large
scale implementation of technologies to
support remote monitoring and control,
automated switching, fast fault location.
 Efficiency along the value chain (1) Aging
equipment with lower efficiency and thermal
losses in conductors are the main reasons
(2) Inefficient distribution transformers
account for about 30 percent of losses.
 Sustainability by integrating renewable
energies over long distances.

10. Risk or Challenges to Deployment
Technical Challenges
 Reliability of AMI technology as well as
AMI billing techniques.
 Impact of high levels of new
technology penetration including
smart-grid technologies, is crucial to
increasing efficient operations on
existing grid infrastructure.
 Managing voltage levels, reactive
power, potential reverse power flows,
and power conditioning with high
penetrations of DG systems, solar and
wind power and PHEVs
 Power quality because customers
have different power quality
requirements (e.g., willingness to
accept outages of varying durations,
and load sensitivity to power
harmonics).
Business and Financial Challenges
 Smart grid investments often require
large upfront costs relative to their
benefits.
 Since the technology and value
propositions are emerging, utility
companies may be reluctant to invest
significant amount of capital to move
toward a smart grid, especially
because expected cost-recovery
timelines are only theoretical and have
no precedent.
 Regulation makes it difficult for them to
raise rates and recover costs, and
makes them reluctant to change.
 The uncertainty about market
penetration is increased when utilities
start to consider the time and cost of
training a new smart-grid-skilled labor
force (NERC 2007).
 As there is DG generation, energy
consumption may be reduced by
individual customer but still Network
Company need to maintain their
network.
