Pilots and demonstrations


The research infrastructure include two full-scale research sites for LVDC microgrids: one located at the campus area and another in the actual utility network operated by the DSO Järvi-Suomen Energia Oy and owned by the energy corporation Suur-Savon Sähkö Oy. The latter is a true living lab. The LVDC network is in constant use and supplies electricity for the daily needs of four residential customers. At the same time it provides an exceptional environment for studying the operation of the LVDC system and an LVDC based microgrid that is a part of the public distribution network.
