Transmission Line Protection Under High Penetration of Inverter- Based Resources: Impact Assessments and Mitigation Solutions

Some areas of today’s bulk power system are at or have already gone past a tipping point where IBR accounts for more than half of the power generation. Such high IBR penetration fundamentally changes the system’s short-circuit behaviors and challenges existing transmission line protection principles. The impact of IBR has been extensively studied and, to some extent, well understood.
