N2 - This paper studies the impact of inverter-based Distributed Energy Resources (DERs) on the performance of Under-Frequency Load Shedding (UFLS) protection. A UFLS misoperation scenario has been identified due to high penetration of DER on the feeders connected to a load substation with a UFLS relay. Essentially, a Load Rejection Overvoltage (LROV) condition caused by DERs may lead to misoperation of the supervising undervoltage element of a UFLS relay, thus causing an unwanted UFLS relay operation. The paper further shows that the likelihood of such a misoperation increases with increased DER integration level. DER onboard overvoltage protection can reduce the likelihood of such a misoperation by limiting the duration of LROV.
