SEMIAH Pilots


Pre-Pilot installation

Until September 2016, SEMIAH has been testing its technology in a pre-pilot phase with 20 households located in Switzerland and Norway. The following installations have been tested:

Results

The test results show that residential heating systems possess enormous potential for exploitation of flexibilities, without causing the prosumer any discomfort.

Pilots 

SEMIAH pilots are rolled out in Switzerland and Norway. In the pilots, water and home heating appliances of each test home are characterized in order to reveal how power cuts will impact on the temperatures and load curves. The goal of the pilots is to identify how long the appliances can be turned off without impacting the comfort of the residents negatively.

The pilot houses can be grouped into 4 categories in Switzerland and 2 categories in Norway, according to the available systems and related measurement variables.

Houses of type 1

  • Control variables (through relays): Heating
  • Power consumption measure: Total consumption
  • Tests possible:

    • Cut heating and assess impact of external condition on indoor temperature
    • To assess the impact of heating on indoor temperature further signal processing is needed to extract the heating consumption from the total consumption curve.

Houses of type 2

  • Control variables (through relays): Heating
  • Power consumption measure: Total consumption, Grid Power, PV power
  • Tests possible:

    • Cut heating and assess impact of external condition on indoor temperature
    • To assess the impact of heating on indoor temperature further signal processing is needed to extract the heating consumption from the total consumption curve.
    • Validation of scheduling algorithm by comparing PV and Grid power with total consumption (does the house consume more when PV panels supply power?)

Houses of type 3

  • Control variables (through relays): Boiler
  • Power consumption measure: Boiler consumption
  • Tests possible:

    • Cut boiler power and assess the impact on boiler temperature

Houses of type 4

  • Control variables (through relays): Heating, Boiler
  • Power consumption measure: Boiler and heating consumption
  • Tests possible:

    • Cut boiler power and assess the impact on boiler temperature
    • Cut heating and assess impact of external condition on indoor temperature
    • Cut heating and assess impact of heating on indoor temperature

User Stories

Have a look at our first user story (French language)

Interviewed by RTS, a SEMIAH pilot project participant explains how flexibilities are provided by a boiler equipped with SEMIAH technology. While the DSO can shift loads from peak- to off-peak hours, the prosumer can save up to 10% percent on electricity bills. The user will not notice a slight increase or decrease in water temperature, when scaled up, however, the DSO is able to relieve a considerable amount of constraint from the grid.

The SEMIAH technology has been designed to optimize electricity utilisation without causing the prosumer any discomfort. The pilots are able to support this premise.
