Title: ENABLING SMART GRID


1
ENABLING SMART GRID METERING
  • GENERATION PORTFOLIO
  • ISSUES and OPPORTUNITIES
  • V.N.Choudhary
  • P.Harisinghaney

2
Enabling Smart GridIssues and opportunities for
generators
  • Paradigm Shift
  • 120 years old Model of
  • Centralised generation and
  • Grid, distribution
  • Network and Consumer
  • Is changing

3
Reasons
  • Regulatory Requirements
  • Fuel Mid change
  • Availability of fuel/Constraints
  • Price of Conventional Fuel Soaring
  • Demand Response changing
  • Environmental Issues Carbon Concern
  • Technology changes in Digital/Electronics/Communic
    ation, Tech/Computation, etc.

4
Contd.
  • Economic reasons
  • Inclusion of Aaam Admi
  • Industrialisation
  • Urbanisation

5
contd
  • Evolution of Standards
  • Quality Concern
  • Interoperability standards an example
  • Cyber Security

6
Concerns
  • Efficiency
  • Waste Reduction
  • Resource Conservation

7
Issues
  • Mix of Generation Portfolio
  • Changing
  • of Renewables
  • Distributed generation is
  • going to increase

8
Alternate Sources
  • With increase in
  • Renewable /alternate sources in grid
  • Intermittent nature of generation
  • Uncertainty will increase
  • Protection standards will change
  • Control will change

9
CONTD.
  • Metering will change
  • Two way interaction
  • Export Import
  • Real Time billing

10
Contd.
  • Billing as per Time of Day
  • Peak time rate
  • Off Peak time rate
  • Export rate
  • Import rate
  • Frequency related rate

11
Contd.
  • Even Central generating
  • Station will have to
  • Adopt Advance Metering
  • Higher sized Units 660 800 MW
  • UHV transmission limes
  • Energy efficiency calculation
  • Internal energy
  • Reactive Power Control
  • Blackout Brown out protection

12
Nature of supply varies
  • Base Load Power supplier
  • Peak Load power supplier
  • Intermittent Load supplier
  • Merchant Power supplier
  • Captive Power supplier

13
Degree of SmartnessIncreasing
  • Right from the beginning i.e. 1888
  • Now it will Lead frog
  • Due to advanced electronics
  • Communication and software

14
  • Relevance of Smart grid elements
  • Generation/distribution
  • For Poverty Elimination
  • Inclusive growth
  • We can use cluster approach

15
Contd.
  • Like Intranet
  • Internet

16
Contd.
  • Clusters of
  • Renewables alternative
  • Resources may be
  • Created at remote places

17
contd
  • These clusters can be
  • Interconnected via
  • High Cap Transmission
  • Lines To
  • Connect rural ,mountain ,and desert located
    population clusters

18
contd
  • Different schemes like
  • RG Grameen Vidutikaran Yojna
  • APDRP
  • MNREGA
  • Urbanisation
  • PURA
  • May be synergised to generate
  • Energy in rural clusters as cottage industry
  • To provide opportunity for small/home industry
  • employment

Solar Resource Availability in India
  • 5000 trillion kWh solar radiation incident in a
    year over India
  • Radiation data collected by India Meteorological
    Department and some other centres
  • Daily solar radiation 4 - 7 kWh per sq. m.
  • Most parts of the country receive solar radiation
    sufficient enough to effectively utilize solar
    energy systems
  • Typically, 2.0 hectare of open space is required
    for one mega watt solar power plant

Issues of solar power
  • Hugh land requirement
  • Production of the solar cells carries an upfront
    cost to the environment via production, but
    offers clean energy throughout the lifespan of
    the solar cell.
  • Intermittent power generation available in day
    time only
  • Low efficiency CUF
  • High capital cost high Cost of electricity
    generated

30
WIND ENERGY IN INDIA
  • Installed Capacity of India 12009.48 MW as on
    30.06.2010
  • India ranked 5th in the World in terms of
    installed capacity after USA, Germany, China,
    Spain.
  • India has a potential of 48,199 MW

31
WIND RESOURCE MAP OF INDIA
32
WIND ENERGY IN INDIA
  • 1150 wind monitoring stations established by
    C-WET
  • States with high potential
  • Tamil Nadu / Gujarat / Maharashtra / Karnataka /
    Rajasthan / Madhya Pradesh / Andhra Pradesh /
    Kerala
  • 216 sites with annual average wind power density
    gt 200 Watts/m2.
  • Wind Atlas for India has been prepared by C-WET.

33
CRITICAL ISSUES FOR WIND ENERGY PROJECTS
  • UNCERTAINTY IN ENERGY ESTIMATION FROM A WINDFARM
  • AVAILABILITY OF LAND
  • SHARING OF FACILITIES
  • INTEGRATION WITH THE GRID
  • PERFORMANCE EVALUATION TESTING
  • OM
  • MONOPOLY OF MANUFACTURERS
  • COSTS ECONOMICS

34
Initiatives in Wind energy by NTPC
  • 650MW capacity addition plan
  • Installation of 100 MW Wind Farm under process
  • MOU signed with KPCL for Development of 500MW
    wind energy projects in Karnataka
  • 100MW wind energy project allotted to NTPC at
    Guledagudda site, Distt. Bagalkot, Karnataka by
    GoK.
  • DPR finalised in-house for Guledagudda wind
    energy project. Approved by Project Sub-Committee
    of the Board of Directors
  • MOU with GPCL for development of wind energy
    projects in Gujarat

35
Hybrid RE Systems
  • In the future, several hybrid systems consisting
    of wind , solar, Biomass small hydro
    installations could be connected in clusters to
    form micro grids which can support the functions
    of the smart grid by firming up variable
    generation.
  • These micro grids can be integrated to a larger
    power system or national grid. Some hybrid
    systems could be the combination of the
    following
  • PV/Battery, PV/Diesel, PV/Battery/Diesel,
  • Wind/Battery Wind/Diesel Wind/Small Hydro
    Wind/PV/Small Hydro Wind/PV/Biomass.
  • Small Hydro/Biomass Small Hydro/Battery/Biomass

36
CONCLUSION
  • Solar Wind energy technologies are pollution
    free and environment friendly and are compatible
    with smart grid.
  • Hybrid systems shall help in firming up the
    variations in generation .
  • Wind energy has very good potential and it is the
    fastest growing energy source
  • The future looks bright for RE technologies as
    smart grid technology will make these
    installations viable and attractive for
    generators as well as consumers.
