Technology
The grid as a marketplace for flexibility.
Our patented price communication turns island grids, micro-grids and grid cells into real-time marketplaces for energy and flexibility. No additional communication network required.
Two signals
Grid physics, translated into prices.
State variables such as frequency or energy flow reflect the situation in the grid. We turn them into signals that every grid participant can receive, understand and act on.
Do supply and consumption match?
Derived from the energy flow into or out of a grid area, or from the grid frequency in island grids. When the sun shines and the wind blows, the BI shows low prices. Flexible consumers benefit by drawing power at those times.
Is the grid reaching its limit?
Shows when transformers or lines are reaching their physical limit, for example during high evening load. Devices then shift their demand before a bottleneck occurs. This saves on grid expansion.
Smart devices
A small software agent in every device.
The agent can be built into standard device controllers at very low unit cost. It charges the EV when power is plentiful, while respecting user settings and technical constraints. Learning algorithms continuously improve the results.
- Integrates seamlessly into existing energy systems
- Easy to operate, maintain and control in an emergency
- No private data leaves the building
Comparison
Decentralised instead of remote-controlled.
| Comparison | Central remote control | Easy Smart Grid |
|---|---|---|
| Communication | Dedicated network, each device addressed individually | Signal via the existing power grid |
| Response time | Minutes to quarter-hours | Seconds, in real time |
| Data | Consumption data flows to the control centre | Stays in the building |
| Resilience | If the control centre fails, the system stops | Every device keeps working |
| Participants | Large installations, high barriers to entry | Any flexibility, of any size and duration |
Automatic merit order
The market ranks flexibility by cost.
All devices take part in the market directly and act in the way that is cheapest for their owners. The market is fully transparent and creates an order in which the cheapest flexibility is used first.
Open and interoperable
Compatible with European standards.
In the EU project InterConnect, we integrated our solution into the SAREF ontology (Smart Appliance Reference) and the Semantic Interoperability Framework. External signals such as dynamic energy and grid tariffs complement local optimisation.
