Task 15 – Network Driven DSM

Task 15 – Network Driven DSM


Task 15 on ‘Network-driven’ demand-side management (DSM) was concerned with reducing demand on electricity networks (grids) in specific ways which maintain system reliability in the immediate term and over the longer term defer the need for network augmentation.

Problems in electricity networks were becoming significant in countries where electricity demand was increasing and network infrastructure (‘poles and wires’) were ageing. As loads grow and infrastructure reaches the end of its economic life, the potential cost of augmenting and providing support services for electricity networks is increasing exponentially.

Task 15 identified and developed a wide range of DSM measures that can:
• relieve constraints on electricity distribution and/or transmission networks at lower costs than building ‘poles and wires’ solutions; and
• provide operational support services for electricity networks, achieving peak load reductions with various response times.

Achieved Results

Task 15 was the first broad and systematic investigation of the potential for DSM to cost-effectively support electricity networks.

Task 15 investigated DSM measures which can be used to relieve constraints on electricity networks (grids), whether these constraints are time-related (eg occuring at times of the network system peak) or location-related (eg associated with particular lines or substations) or both.  All types of constraint were addressed, including capacity limitations, voltage fluctuations, reliability issues, etc. Such network-driven DSM measures are often more cost-effective, and may also have lower environmental impacts, than network augmentation (ie building ‘poles and wires’).

In addition to relieving network constraints, DSM measures can also provide operational support services for electricity networks, including:  reactive supply and voltage control, regulation and frequency response, energy imbalances, spinning reserves, supplemental reserves, and generator imbalances.  Task 15 also covered the use of DSM measures to provide network support services.

Task 15 identified and developed a wide range of DSM measures which can be used to relieve electricity network constraints and provide network support services.  Network-driven DSM measures include:

  • direct load control;
  • distributed generation, including standby generation and cogeneration;
  • demand response;
  • energy efficiency;
  • fuel substitution;
  • interruptible loads;
  • integrated DSM projects;
  • load shifting;
  • smart metering;
  • power factor correction; and
  • pricing initiatives, including time of use and demand-based tariffs.

Task 15 facilitated international collaboration between countries.  Participating in Task 15 was a very effective way of gaining valuable information about international experience in using DSM to support electricity networks. Since the costs were shared among a number of countries, the financial contribution required from each country was quite small compared with the benefits gained.
