Existing industry standards such as IEEE 1547 covers DER interconnection criteria and requirements but does not cover the methods and requirements to trip DER by the utility protection and control system when there are system events such as faults and how traditional electric protection devices such as relays evaluate and perform the DTT operations. In this application, the utility relay protection control system has a range of tasks to perform and coordinate with the DER protection and control system, including: fault management; evaluating the criteria to perform DTT; preventing DER islanding; speed and sensitivity to perform DTT, and other performance capabilities.
