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

Contd.

contd

Issues Mix of Generation Portfolio Changing % of Renewables & Distributed generation is going to increase

CONTD.

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

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

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

Degree of Smartness Increasing Right from the beginning i.e Now it will Lead frog Due to advanced electronics & Communication and software

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

Contd. Like Intranet & Internet

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

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

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

 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 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 Solar Resource Availability in India

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

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

WIND RESOURCE MAP OF INDIA

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 > 200 Watts/m 2. Wind Atlas for India has been prepared by C-WET.

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 O&M MONOPOLY OF MANUFACTURERS COSTS & ECONOMICS

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 Initiatives in Wind energy by NTPC

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;

 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.
