Summary / Abstract:
Over the last years the role of microgrids have been increasing steadily and they will play a more important role in future power grids with the aim to provide a more resilient electricity supply. Microgrids are usually low-voltage networks, which can operate grid-connected or isolated from the main grid. The microgrid control system manages the transition between grid-connected and islanded mode and is also responsible for energy dispatch functions. Testing this control system is crucial for safe and reliable operation of microgrids. Thus, IEEE-SA published the IEEE 2030.8-2018 – Standard for the Testing of Microgrid Controllers in August 2018. It provides a test methodology for the verification and quantification for the performance of different microgrid controller functions. The work in this paper validates the usability and applicability of the standard by laboratory tests in the Smart Grid Technologies Laboratory (SGTL) of TECNALIA, in Spain. Experiences and lessons from the tests, as well as measurement results will be presented.
