  • This presentation is actually an analysis into the heart of the Indian power sector; what are the problems that the Indian grid is facing and what is the best possible solution to solve them. Smart Grid proposes a dynamic electricity management system which seems to be the need of the hour for the Indian electricity System
  • India’s Location with respect to the world.
  • Tropic of Cancer passes through the country and half of the country is tropical while as half is sub tropical.
  • The population of the country shows a bulge when compared to other countries of the world.
  • Most of the population is concentrated in the East and the South of the country because of the favorable weather and a lot of commerce.
  • Over the years, India and China have shown a steady growth in terms of their Energy consumption while as the OECD countries show a constant energy consumption. This is mostly because of the huge growth rate in India and China.
  • Total Energy Consumption in the country is at a steep rise.
  • Carbon dioxide emission of China is nearly 5 times more as that of India. The electricity installed generation capacity of China is nearly 5 times more than India.
  • The demand for electricity is constantly outstripping the supply and the gap is ever widening.
  • The electricity production is increasing at a steady growth rate trying to match the demand because of the increasing population.
  • More than half of Electricity produced in the country is from conventional fuels and needs a change to a more sustainable and green fuel source.
  • All three facets of extracting electricity from the utilities to the consumer face some very strong issues.
  • There has been a transition from the needs of consumers a century before to today.
  • Grid modernization involving latest technologies and better storage options for integration of renewable energy is important.
  • Smart Grid provides the solution to all of the issues facing the India’s electricity grid.
  • The Smart Grid has to be deployed in certain steps and phases.
  • Even though not a very strong contender for smart grid deployment in India, Home Area Network is a very important parameter for the final green and reliable electricity system in India and abroad.
  • Renewable Sources of energy provide clear benefits over the conventional fuels.
  • Over the years, the Indias Renewable Energy Scene has observed a very steady growth and the growth is expected to continue.
  • Renewable Energy is one of the most important drivers for the Smart Grid deployment in the country. Smart Grid can do a fairly good job in integrating the energy from renewable sources into the grid.
  • Renewable Energy is highly distributed in the country.
  • Wind Energy has gained a lot of ground over the years mostly because of improvement is the wind turbine technologies as well as wind estimation technologies.
  • Banking on government backed missions such as the Jawaharlal Nehru National Solar Mission, tapping solar energy is one of the most important thrust areas for smart grid deployment in the country.
  • Most of the potential Solar resources for electricity generation are found in the western region of the country in the states of Gujarat and Rajasthan.

  • Electricity Scenario of India Key regulatory bodies in the Indian Power Sector Department of Atomic Energy Ministry of Power Central Electricity Regularity Commission Central Electricity Authority State Electricity Regularity Commissions Installed Capacity: 220 GW Peak Demand: 170 GW Peak Deficit: 8.6 % Energy Deficit: 4.8 % Growth Rate: 8-9 % PA For the Year 2011 Source: Central Electricity Authority
  • Issues Facing India’s Power Sector Generation Side Transmission Side Distribution Side
  • Generation •Fuel (Coal and Gas) Shortage is acute. •Many power plants have less than seven days' of coal stocks, a level seen as critical to continuous operation. •Present demand–supply gap of coal is around 85 million tons and it is expected to increase gradually to nearly 140 million tons by 2017. •Capacity addition from hydropower sources slowed in the past couple of years
  • Transmission • A huge 12 percent of the electricity generated is lost while evacuating power to the consumers as Transmission losses which can go to as high as 50 percent in some states. • The officially declared transmission and losses in India have steadily risen from about 7 percent up to the year 1966-67 to about 12 percent in 1998-99
  • Distribution •Distribution companies, mostly state-owned, are mired with about $35 billion in debt barring them from investing more into the R&D and up gradation of their utilities. •The estimated loss of all the State distribution utilities has been estimated at Rs 2400 million as of March 31, 2012
  • Before And Now •Grid infra-structure established over a 100 years ago •Main purpose was to supply electricity to a few loads •Power Generation was localized and built around small communities (State of Transition) •The needs of the civilization are not modest anymore •Grid structure is becoming complex with every passing day and loads are increasing in size and convulsion •A constant interest related to integrating variable sources of energies that give rise to harmonic instability.

  • Smart Grid, A Remedy Issue What a Smart Grid can do? •Supply Shortfalls A Smart Grid better manages the integration of all available resources of energy into the grid. •Huge Losses Allows the integration of Distribution Energy Resources (DER’s) that can allow localised generation hence reducing the transmission and equipment losses •Human element in system operations Provides the platform for introduction of Advanced Metering Infrastructure (AMI) for a better User Interface (UI) •Peak Load Management Allows a perceptive load control which can prevent the peak time shortfall •Integration of renewable energy Manages problems caused by intermittency and distributed power
  • Smart Grid Deployment The ‘Smart’ in a Smart Grid is an Information Communication Technology (ICT) that brings together a variety of computing and telecommunications technologies. The ICT enables the Smart Grid’s envisioned benefits to become a reality. Source: www.siemens.com
  • Technology of Smart Grids Smart Grids encompass a wide range of operations such as • detecting and identifying faults and a quick response to power outages, • providing consumers with near real-time information on the amount and cost of the power they use, • improving the security of the system, and • linking all elements of the grid to enable better decision making on the resource use. Various technologies in action • Supervisory Control and Data Acquisition (SCADA) • Distribution Management System (DMS) • Distribution Automation System (DAS) • Automated Meter Reading (AMR) • Geographical Information System (GIS) • Phasor Measurement Units (PMU’s) Source: www.sandiegofreepress.org
  • Home Area Network Home Area Network (HAN) connects thermostats, refrigerators and other electrical devices in a Smart Home to an energy management system Source: www.smartgrid portal.org
  • Integration of Renewable Energy Integration of Renewable Energy is probably the biggest thrust for a Smart Grid Deployment in India • Has to be converged at grid operator level and requires a superior Energy Management System • The Smart Grid’s superior capability of introducing new sources of energy to the grid clearly signifies that more Distributed Generation can be integrated into it Solar and Wind energy are crucial and primary factors of a cleaner and greener energy future
  • Demerits of Conventional Fuels Coal • Dependence on imported coal is on the rise, supply from the local quarries is on a shallow decrease on account of production and analytical constraints Oil • Energy Security and Political Instability always tan the oil import scenario of the country Natural Gas • Domestic gas resources are limited. Moreover RLNG is costly and not a feasible option for power generation Hydro • Even though India is rich in Hydro potential but harnessing Hydel potential to meet the requirements is a challenging task
  • India’s Renewable Scenario As on November 2012, 12% of total installed capacity (210 GW) through renewable sources • Wind (18.3 GW) • Small Hydro (3.4 GW) • Biomass (1.2 GW) • Solar (1 GW) Progressive Renewable Sector 2012 Small Hydro 3395 MW Solar 941 MW Biomass 1950 MW Wind 18352 MW 2017 est’d Small Hydro 4995 MW Solar 4741 MW Biomass 3250 MW Wind 28352 MW
  • The Role of Renewable Energy • • The notion of renewable energy as an “alternate” form of energy is no longer a valid argument. India is currently ranked 5th in the world in all renewable energy fronts. Source: www.indexmundi.com
