Problems with microgrid protection
The main protection challenges in the microgrid are the bi-directional power flow, protection blinding, sympathetic tripping, change in short-circuit level due to different modes of operation, and limited fault current contribution by converter-interfaced sources. Additionally, they reduce the load on the utility grid. However, given that they depend on unplanned environmental factors, these systems have an unstable generation. Microgrids help leverage these DERs to keep the power on when the normal supply is unavailable (e. There is no guarantee that behavior of DERs will be common amongst device types or even amongst vendors.
