As inverter-based generation sources become more common, reliability requirements increase; protection and control systems must isolate faults faster and with better selectivity. This paper analyzes the impact of various digital secondary system designs on the reliability and performance of power systems. https://lnkd.in/gDB62Zsd #DSS #PowerSystemReliability

According to the Department of Energy, 70% of U.S. transmission lines are nearing the end of their lifecycle. Aging systems increasingly fail to meet modern needs, lacking wildfire and extreme weather resilience, cybersecurity hardening, and distributed generation flexibility. Luckily, grid modernization—and the benefits entailed—are within reach.

As the grid becomes more reliant on inverter-based resources like solar, wind, and battery storage, ground faults get harder to detect with traditional methods. Read our new technical paper to learn how you can improve directional element sensitivity and maintain security in mutually coupled lines near one of these resources: https://lnkd.in/gu7av7M6 #TransmissionLines #IBR #PowerSystems
