Simulation Models

The following simulation models are included in SiENA and can be extended easily.

Households

Households are seperated into three different parts, representing different amount of smartness.

Conventional Household

  • Basic behaviour without any optimisation
  • Follows the behaviour of the device simulation models

Smart Home

  • Household with smart devices
  • Household optimises itself

Grid Home

  • A smart home which can communicate with other smart homes via a communciation technology
  • Performs distributed energy management using one of the algorithms

Devices

Common household devices are already integrated into the baseload of a household. The remaining devices, which offer additional flexibility, are divided into three types. A DEM algorithm has access to these devices.

All parameters can be adjusted freely in the configuration.

Shiftable Devices

  • Activation time can be shifted to a later point in time
  • Washing machine, tumble drier and dishwasher
  • Parameters
    • Activation time (by resident)
    • Deadline (device must have finished its cycle until then)

Adaptable Devices

  • The energy consumption and generation can be adapted freely
  • Parameters
    • Desired consumption
    • Minimum consumption (might be negative)
    • Maximum consumption (might be negative)
    • The DEM algorithm can choose freely in between
  • Battery Storage
    • Charging power can be reduced freely or even reversed to feed into the power grid
    • Desires to be charged to 50% to provide flexibility
    • Parameters
      • Capacity
      • Efficiency
      • Power
  • Electric Vehicle
    • Battery storage with occasional trips (charge is reduced after trip)
    • Requires a minimum 90% charge level to guarantee user acceptance
    • Minimum and maximum adaption depends on state
    • Parameters
      • Capacity
      • Fuel economy
  • Heating Rod
    • Acts as a backup for heating devices below 15% charge level
    • Can be activated to consume surplus power
    • Parameters
      • Power

Switchable Devices

  • Can be switched on or off
  • Heat pump
    • Heats a water tank
    • Desires a 50% to 75% charge
    • Has to run for at least 2000 hours a year
    • Has to run for at least 15 minutes before being switched off to reduce wear
    • Parameters
      • COP
      • Power
  • micro CHP
    • Heats a water tank while generating power
    • Desires a 50% to 75% charge
    • Has to run for at least 5000 hours a year
    • Has to run for at least 120 minutes before being switched off to reduce wear
    • Parameters
      • COP
      • Electrical power
      • Heating power
