Demand side management,

  1. 1. DEMAND SIDE MANAGEMENT By Surya muttamsetty
  3. 3. WHAT IS DSM “Demand Side Management” is the modification of consumer’s demand of electricity through various methods such as financial incentives and consumer education Usually the goal of DSM is to encourage the consumers to use less energy during peak hours or to move the time of energy use to the off-peak hours
  4. 4. WHAT IS DSM …..(CNTD) DSM is universal and does not only apply to utilities, electricity or monopolies IN SHORTLY, DSM = Large-Scale Deployment of Energy Efficient Equipment by use of specially designed Programmes
  5. 5. THE ISSUES Load level a wasteful demand requires too much supply for the specific needs Load shape high peaks, little reserve capacity, bottlenecks in transmission and distribution
  6. 6. FROM THE GRAPH The peak demand of 225 KW is there for an average of 12 hours in a day The base demand is 125 KW, which is much less than the peak demand of 4,300 MW To meet the extra demand utility has to arrange additional installed capacity or purchase power at high rate
  7. 7. Cntnd….. Thus DSM will always try to encourage consumers to: Use less energy during Peak hours (Peak Clipping) Shift energy use to off peak hours (Valley Filling)
  8. 8. NEED FOR DSM Increasing energy requirement Increasing threat of climate change and other environmental considerations Energy security Lack of other supply options Huge scope for energy efficiency measures
  9. 9. NEED FOR DSM ….(CNTD) Saving 1 unit of electricity at consumer end avoids nearly 2.5 times of capacity addition 1 MW capacity addition of thermal power requires Rs 6 crores for installation and another Rs 3 crores for Transmission and Distribution
  10. 10. IMPLEMETATION OF DSM There are 3 methods to implement dsm 1. ENERGY EFFIENCY 2. DEMAND RESPONSE 3. DYNAMIC DEMAND
  11. 11. Energy Efficiency: Using less power to perform the same tasks Demand Response: Demand Response includes all intentional modifications to consumption patterns of electricity of enduser customers that are intended to alter the timing, level of instantaneous demand, or the total electricity consumption Dynamic Demand: The concept is that by monitoring the power factor of the power grid, as well as their own control parameters, individual, intermittent loads would switch on or off at optimal moments to balance the overall system load with generation, reducing critical power mismatches
  12. 12. STEPS TO BE FOLLOWED To charge higher prices during Peak Hours Improving the efficiency of various end uses by using energy efficient appliances, better house keeping and reducing energy leakages. This is important for agriculture where energy efficiency is very low (30-50%) Promoting use of Energy Efficient Technologies and addressing Aggregate Technical and Commercial (AT&C) Losses
  13. 13. CHANGE IN THE LOAD SHAPE Adapts the load to the capacity of the system Before After
  14. 14. Benefits of Demand Side Management Customer Benefits Utility Benefits Societal Benefits Satisfy electricity demands Lower cost of service Reduce environmental degradation Reduce / stabilize costs or electricity bill Improve operating efficiency, Flexibility Conserve resources Maintain/improve lifestyle and productivity Improve customer service Protect global environment 15
  15. 15. PROBLEMS OF DSM It might result in higher utility costs for consumers and less profit for utilities. Another problem of DSM is privacy: The consumers have to provide some information about their usage of electricity to their electricity company. Dissatisfaction may arise among the consumers
  16. 16. FINAL THOUGHT…. DSM leads to, i. Energy efficiency ii. Industrial development iii. Energy security
