The EnergyVille Low Voltage Grid Lab is a platform for testing smart grid products and systems
In the Low Voltage Grid Lab, our highly experienced team executes tests and validates:
- Power line communication systems in distorted grids
- Long-term automated cycling of Li-ion batteries and reference performance tests
- Research on low voltage distribution grids with a high amount of renewable energy sources:
- Development & testing of Intelligator: an agent-based control algorithm to match supply and demand of energy
- Power quality: voltage dips, phase unbalance, harmonic distortions
- Voltage droop control: taking grid constraints into account by power adjustments
- Inverter control algorithms for unbalanced grid conditions
- Data analysis:
- Different energy flows (V, I, cosφ,..) are logged in a dedicated SCADA system
- Accurate high speed PQ measurements according to EN 50160
