Laboratory use

Smart Home Management System

Test of devices, equipment, control technology and strategies for smart home energy, indoor climate and home security and safety. In the project, different architectures (central intelligence versus distributed intelligence) and systems (e.g. LonWorks, KNX,...) were investigated and tested for different scenarios realising basic functions such temperature, ventilation and light controls, integration with smart meters, remote control, smart phone integration etc.

Multi-terminal HVDC grid connecting offshore wind farms

Large multi-terminal HVDC grids are predicted for future implementation. We verified a control strategy that will ensure safe and stable operation of such grids. This was done using a future scenario featuring a North Sea supergrid connecting 3 countries with a large share of wind power (> 50%). The strategy maintained grid stability despite large variations in produced wind power. The number of converters and machines of the lab enabled this large and complex experiment.

Frequency support from wind turbines

If wind turbines can support the electrical grid operation during faults then larger wind farms can be installed in areas with weak grids. We verified and quantified the effect of different control strategies on wind turbine performance during faults. The quantification included the effects of implementation on real hardware compared to software simulation. Tests were done for the two prevailing generator technologies that are used for wind turbines.

Product testing and verification

New products and solutions often need to be tested and verified in laboratory conditions before being commercialized. We have provided a test platform for different manufacturers to test their equipment, e.g. voltage boosters, short-circuit impedance measurement tools and power quality analysers.

Micro grid

The integration of real-time simulated power systems and controls interfaced with a small model micro grid is shown in the figure. The objective of the setup, is to test various microgrid control strategies.

200 kVA Power Hardware in the loop (PHIL)

The purpose of the 200 kVA PHIL solution in the Smart Grid Laboratory is emulate power systems, devices and controls and their integration to physical model power systems, devices and controls to study system behaviour and performance for a reasonable power ranges and frequencies. The advantage compared to the testing of use cases at very low powers and voltages, is the ability to model certain physical phenomena in a realistic way (e.g. rotating machinery thermal effects and time constants). The figure shows the Power Hardware in the Loop setup with the OPAL RT real-time simulators (OP5600), the I/O devices (OP4520) and the 200 kVA, 5kHz Egston power amplifi er.

Example of physical power system setup

The Laboratory is very flexible with respect to topology and configuration.
