Flex Power Grid Laboratory (FPGLab)
Description: The Flex Power Grid Lab in Arnhem takes a unique position in the world because of the voltage and power range of 24 kV and 1 MVA together with a bandwidth of 2.4 kHz (for harmonic superposition). The laboratory is built around a fully programmable four-quadrant power electronics converter that can either create a grid with a customisable power quality level or represent a custom load. The laboratory has been designed to enable for example the circulation of power from the programmable source, through the device under test, back to the feeding grid. Additionally, various passive loads are available in the lab for easy connection.

FPGLab laboratory is not like any of the already existing KEMA laboratories, not in functionality, purpose nor organizational structure. The laboratory is owned, and run, by the independent foundation called the “Stichting EMVT Laboratorium”. KEMA has an exclusive 50% share in this foundation and the Dutch government the remaining 50%. KEMA will provide exclusive trans-national access to the Flex Power Grid Lab facility from its 50% share in this foundation through sub-contracting of the “Stichting EMVT Laboratorium” foundation.
The laboratory is in operation since 2008 and focuses on Distributed Energy Resources (DER) and Renewable Energy Systems (RES) integration for SmartGrids and power electronics development and testing for industrial high voltage (24kV) and power up to 1MVA, by offering a predefined “bad” grid or load.
