AITLemcko was founded in 1998 as an independent academic research institute focusing on electrical motors, drives and electrical power quality to provide substantial research for its industrial partners. Since then, there has been a continuous growth in manpower, knowledge and expertise in low frequent power quality (<2kHz), general low voltage electrical installations, energy-efficiency and renewable energy connected to the low voltage distribution grid.

In 2013, Lemcko has become part of the University of Ghent in order to increase academic collaborations and its international recognition. Over the last two decades, the functionality and the stress on the distribution grid has significantly increased. Lemcko’s ambition is not to elaborate on advanced theoretical modeling or forecasting algorithms but instead to facilitate the transition from innovative academic research to real-life integration of these innovations into the low-voltage grid. The laboratory comprises an extensive amount of practical and theoretical knowledge in combination with a state-of-the-art test facility. Lemcko has a unique test site consisting of 18 real connections of households to an actual distribution feeder of 600m. The combinational use of the distribution grid and a 240kVA programmable power source enables testing of innovative consumers and producers as well as measuring equipment in order to tackle future problems related to the practical integration proactively. In electrotechnical engineering the evaluated frequencies are often limited to the 40th harmonic (or 2kHz). However, recent studies indicate that future problems to distributional grids may include supraharmonics (>2kHz) and electromagnetic compatibility and immunity (>9kHz). The laboratory has expanded its area of application, the test equipment and its expertise to cover these frequency ranges. The availability of a semi-anechoic chamber and the corresponding measuring equipment allows Lemcko to perform IEC and CISPR compliance testing.
It is, however, the lack of power as in voltage dips or short- or long-term blackouts that may affect the end user most noticeably. In 2012, Lemcko initiated research focusing on small-scale storage and autonomous generation of electrical power. Test facilities include a free-programmable power electronic converter (Tri-phase platform), 10kWp PV installation with tracking possibilities, net interactive PV converters in combination with battery storage and several autonomous generators. Future investments include a test facility for motor and generator testing of 150kW. This would allow for the possibility to test high power, high current as well as low speed generators such as the ones used in windmills 100kW.
