Summary
This paper considers the behavior of inverter‑based resources (IBRs) during short circuits
Read more Read less(faults) within wind power plants (WPPs) and solar power plants (SPPs) integrated into the
Russian power system. The relevance of the study is driven by fundamental differences between short‑circuit current characteristics of IBRs and synchronous generators (SGs). In conventional power systems, fault current is defined by machine electromagnetic characteristics and circuit impedance, whereas for IBRs it is governed by control algorithms and configuration parameters of power‑electronic controllers, which vary among manufacturers. These differences create significant risks for the reliable operation of relay protection and automation (RPA) devices.
