Control house storage according to network status

Electricity storage units in the basement can also be controlled remotely – and can absorb energy from wind and solar parks that is currently not needed. In the future, many such storage facilities will be able to reduce bottlenecks in the electricity grid – by storing energy temporarily.

Intelligent home storage facilities

Intermediate storage of regional excess electricity supply

Milestones

Spring 2016
Development of the concept
October 2016
Start of testing: Three battery storage units installed for test client
Summer 2018
End of measurement and evaluation

At a glance

Name: House accumulator as controllable consumption device

Status: Pilot operation

Goals: Testing of home storage facilities for a more flexible electricity grid; creating the conditions for grid-stabilizing home storage facilities to be recognized as “controllable consumption device”

Comments on the project

Optimising one’s own household with storage systems – this is what many players in the market are dealing with. What is new about our project is that even households without their own electricity generation can contribute to the integration of more renewable energy.“

System
1
Household with battery storage
2
Household with battery storage and heat pump
3
Household with battery storage and domestic production
Objective
1
Creating basis for recognition according to §14a
2
