Facilities

Smart Electricity Systems and Technologies Laboratory (SmartEST)

Description: The AIT SmartEST, located in Vienna, Austria, provides a multifunctional research, validation, and testing infrastructure allowing the testing of single devices as well as analysis of the interactions among multiple power system components – especially Distributed Energy Resource (DER)-based inverter systems – and the power grid under realistic, nearly real-world situations. The laboratory includes three configurable three-phase low-voltage grids; a high-bandwidth, programmable power grid simulator; several Photovoltaic (PV) array simulators; and an environmental test chamber for emulating various environmental conditions. This permits the validation and testing of DER-based inverter systems at full power under extreme temperature and humidity conditions and the investigation of their interactions under various power grid conditions. The facility is capable of testing in-verters, storage units, grid controllers, and Combined Heat and Power (CHP) units as well as charging stations/supply equipment for electric vehicles in the power range from a few kVA up to 1 MVA.
Designed as a pure low-voltage research and testing environment, all AC buses are rated for operation at voltages of up to 480 V (line to line). The laboratory itself is supplied from the local 20 kV medium-voltage power grid via two independent medium- and low-voltage (MV/LV) transformers. The test facility has been used for comprehensive performance testing of DER equipment as well as qualification testing to national and international grid codes and standards based on the extensive range of accreditations held by AIT. Research on procedures for advanced interoperability testing of single as well as multiple DER units under different grid control schemes supports the integration of DERs into a future smart grid through standardized communication and coordination among generators, consumers, and storage units.
The lab is in operation since 2013.
