What It Takes to Run a Grid on 100% Inverter-Based Resources
What it takes to run a grid on 100% inverter-based resources: inertia, fault current, system strength, a worked RoCoF example, and how operators got there.
Grid-Forming Inverter Requirements: Specs and Compliance Testing
Grid-forming inverter requirements explained: GC0137, AEMO, IEEE 2800.2 and UNIFI specs, the key tests, and a worked phase-jump current-limit example.
Stability Screening for IBR-Rich Systems Using SCR, RMS, and EMT
Stability screening for IBR-rich systems: SCR and WSCR limits, when to escalate from RMS to EMT, with a worked WSCR example and real ERCOT and AEMO cases.
Reliability Services From Inverter-Based Resources: What the Grid Code Requires
Reliability services from inverter-based resources, mapped to grid-code rules: frequency droop, reactive support, ride-through and a 0.95 PF example.
