Are multifunction protective relays a good choice for Microgrid controls?
Multifunction protective relays are an economical choice for microgrid controls because the hardware is commonly required at the point of interface (POI) to the electric power system (EPS) and at each distributed energy resource (DER). The relays at the POI and DER provide mandatory protection and human safety.
What is a microgrid relay?
In smaller microgrids, relays are commonly utilized for control, metering, and protection functions. In larger microgrids, the functionality of the microgrid controls is predominantly performed in one or more centralized controllers.
How to protect a microgrid?
Establishment of a proper grounding architecture for effective protection device operation [190, 191]. Dynamic protection is needed that can adapt to the changing microgrid conditions . Utilize FCL to reduce fault current levels and stress on protection devices .
Can a voltage-based protection scheme differentiate a fault from a microgrid?
Due to the limited fault current and short lines across the microgrid, the voltage profile seen by relays across the microgrid for a particular fault is nearly the same; therefore, using voltage-based protection schemes in differentiating faults seems challenging.
