Study Notes

Demand Side Management (DSM)

  • DSM aims to reduce load shedding percentage and increase penetration level of renewable energy
  • It helps to reduce cost, improve environmental and social conditions, and enhance reliability and network issues
  • Promoting DSM leads to improved markets and customers' response to dynamic prices

Types of DSM

  • Energy Efficiency: reducing energy consumption while maintaining same service level
  • Energy Conservation: reducing energy consumption without compromising service level
  • Demand Response (DR): changing consumption pattern in response to changes in price or other incentives
  • Load Management: utilities controlling customers' loads to manage peak demand

Demand Response Programs

  • Load Response: utility offers payment or incentives for reduction of demand during specified periods
  • Price Response: customers voluntarily reduce demand in response to forward market prices
  • Direct Load Control (DLC): utility remotely controls customers' loads with prior agreement
  • Interruptible/Curtailable Load Tariff (I/CLT): customers agree to switch off loads as requested by utilities
  • Emergency Demand Response Program (EDRP): customers paid incentives for measured load reductions during emergency conditions

Price-Based DR Programs

  • Time of Use (TOU): rate differs in different time blocks
  • Critical Peak Pricing (CPP): high electricity price during system contingencies or high wholesale prices
  • Extreme Day Pricing (EDP): high electricity price for the whole 24 hours
  • Real Time Pricing (RTP): hourly fluctuating prices reflecting the real cost of electricity

Benefits of DSM

  • Reductions in customer energy bills
  • Reduced need for new power plants, transmission, and distribution networks
  • Creation of long-term jobs due to innovations and technologies
  • Reduction in air pollution and dependency on foreign energy sources
  • Reduced peak power prices for electricity

Challenges of DSM Programs

  • Lack of information, communication, and technology infrastructure
  • Lack of awareness about DSM and its benefits
  • DSM increases system complexity compared to traditional approaches
  • Improper market structure and lack of incentives
  • Difficulty in changing distribution system network
