LINEAR (Local Intelligent Networks and Energy Active Regions) is a project funded by Instituut voor Wetenschap en Technologie (IWT) of the Flemish government (Belgium). It aims at realizing an implementation breakthrough for automated residential demand response by means of a pilot and to evaluate the technology, economical value and consumer acceptance.
It consists of two main parts, a scientific breakthrough and a large-scale demonstration involving more than 250 households. Different demand response market mechanisms are investigated:
An overview of the general set up and objectives of the project is given in Figure 1.

The field trial
Demand-side management infrastructure is rolled out in the field according to Figure 2. Around 500 household controllable appliances are used: electric vehicles, domestic hot water buffers, washing machines, dishwashers and tumble dryers. Around 80 PV panels are included in the project as well.
The in-home Energy Management System (EMS) is based on a zigbee plug network which is used for the metering of the appliances. The control signals are sent via Ethernet or PLC. Thanks to these demand response technologies, the users can visualize their consumption and the different tariff schemes with a tablet.

- Starting the project, a large-scale survey with more than 2000 participants was performed to be able to study the potential for scaling up of the project results in a statistically relevant way.
- The influence of PV panel penetration and increasing load on different types of feeders have been simulated to anticipate the business case of using flexibility to defer grid upgrades.
- Different forms of small-scale storage technologies (electric storage and thermal storage), have been studied in detail. The effect of battery storage on the grid voltage has been simulated.
- The integration of electric vehicles and mobility are part of the field trial and can provide significant problems for the evening peak. Different coordination schemes are studied.
