The Interconnection Protection of the MV Multiple Microgrid

Abstract:

The MV multiple Microgrid includes not only a lot of DGs, and may also contain some small microgrids. To the large scale MV multiple microgrid, the interconnection protection problems of different levels microgrid will decide the safe and stable operation of the maximum range. In this paper, list the challenges which are crucial to the microgrid protection, put forward a protection scheme based on the digital integrated protection terminal (DIPT) to solve these problems according to the structure characteristics, analyze the basic principle with comparing composite modulus of fault currents in a DIPT control zone to identify the fault branch and the necessary communication scheme between DIPTs is discussed. At last, build the system model in PSCAD/EMTDC and verify the theory feasibility in different operation modes and different fault types.
