Load modelling

Essential in local energy planning is the estimation of the demand for various energy services, such as:

  • Light
  • Mechanical work
  • Heating (space heating, cooking, hot water..)
  • Cooling (air condition, refrigeration..)
  • Electronics (PC, TV, stereo…)

Load models can be used to forecast the energy demand both on short term operation of an energy system and on long term expansion planning involving substantial irreversible investment decisions.

Load modelling can be defined as aggregation of spatial, individual energy demand specified in time. In practice this is done by establishing representative load profiles for defined customer categories with similar demand.

On this page you can find information about load modeling for local energy planning and about various methodologies for load modelling.
