demand side management

  1. 1. A Presentation On….. BY: Komal Nigam 132113106 M.Tech. 2nd Sem Power System 1
  2. 2. Indian power sectors Future of demands What is DSM Why balance supply and demand Examples of DSM DSM planning procedure Barriers to achieve ideal DSM Problems Conclusion 2
  3. 3. 3 More than trebled installed capacity in the last two decades. Large energy deficit and still larger peak power deficit. Long hours of load shedding in different parts of the country.
  4. 4. 4
  5. 5. 5
  6. 6. The demand is likely to grow at a pace more than envisaged Economy growing rapidly Expected growth might be much higher Growth is linked to energy availability We must generate more energy for the growth of economy 6
  7. 7. Controlling the quantity of energy used at specific times to reduce system peak demand load levelling reduce overall system demand energy efficiency balance system supply and demand demand response 7
  8. 8. Maintain minimum demand levels to minimize waste prevent strategic base load plant shutdowns Keep a low maximum demand avoid building new power plants reduce emission of GHG & other pollutants lower use of peaking plant power 8
  9. 9. Metrics Actual Peak Reduction (MW) Annual Effects (MWh) Direct Load Control Other Load Management Energy Efficiency 9
  10. 10. Balancing Supply & Demand During periods of high demand Interruptible customers During periods of low demand Energy storage Energy incentives Ex: Off-peak incentive rates Minimizing Peak Power Requirements Energy Efficiency Programs Smart Metering (real-time pricing) 10
  11. 11. 31% 26% 9% 9% 7% 18% Residential Electricity End Use Climate Control Kitchen Appliances Water Heating Lighting Laundry Appliances Other 11
  12. 12. DSM can Change the LOAD SHAPE Before After
  13. 13. Strategic growth From this Strategic Saving To This Or to this DSM can change the LOAD LEVEL
  14. 14. Load Leveling Strategies 14
  15. 15. Supply side alternatives Capital Costs Fuel costs Load forecasting Generation Planning Production Costing Financial Analysis Rate Allocation Iterate as necessary Need to Predict & Provide for: Long Term Planning More Lead time Rising Costs Environmental Impacts Tools: Demand Side Management
  17. 17. Lack of support mechanisms Inadequate capital investment Inadequate information to public Split incentives 17
  18. 18. Energy and peak power shortage which leads to load shedding Normally unannounced Is there a way to overcome load shedding inspite of the shortages? 18
  19. 19. What consumers do during load shedding • They suffer, silently and helplessly • Some have invested in diesel generators • Many have purchased inverters • This is expensive for the middle class and out of reach for the poorer section of society • They cater to a part of the lighting load only • Difficult to run refrigerators, water pumps ,AC • Inverters are energy guzzlers – Consume nearly twice the energy to charge their batteries after they have been used – Further increases the loss due to harmonics 19
  20. 20. Load management using load rationing is actually an effective way forward for Demand Side Management It will be a far more effective and a sure way to manage peak demand at the time of shortages as compared to influencing consumer behavior using TOD tariffs It will help in conserving energy The energy consumed by the batteries of the innumerable inverters will also be saved. 20
  21. 21. To achieve widespread DSM success Energy efficiency New technologies Widespread load levelling use Real-time pricing Off peak incentives Energy storage 21

  23. 23. Development Sponsored by World Bank Vietnam Established DSM Projects Italy Australia South Africa 23
  24. 24.  Without the more effective use of energy we would have to use 50% more energy than we actually do today.  Demand Side Energy Management focus on harnessing clean energy.  Reliability, security and quality of power supply are the main concern of DSM. 24
  25. 25. We have achieved many mile stones yet the further journey to achieve high customer satisfaction is on the horizon through DSM 25
