DETL Fact Sheet

The Distributed Energy Technologies Laboratory (DETL) provides power electronics testing capabilities including island and campus grids, remote operations, and scaled portions of utility feeders and the transmission infrastructure. DETL includes a 480V, 3-phase microgrid, with interconnections to the utility grid and to various distributed energy resources including PV inverters, microturbines, fuel cells, reciprocating engine-generators, and electrical energy storage systems. DETL provides expertise and test support to perform the following functions:

  • Grid-connected performance evaluations (e.g., efficiency, distortion, power factor, response to abnormal grid conditions)
  • Off-grid (stand-alone) performance evaluations (e.g., transient response, compatibility with various load types, voltage and frequency regulations)
  • Specialized tests (e.g., radio-frequency emissions, “non-islanding inverter,” interactions of multiple sources on a common microgrid, surge tolerance)
