“…Several control strategies exist for GFMI, but all are expected to improve converter-driven stabil-ity and damp undesired controller interactions. In addition to the expected cost savings in some cases GFMI may be able to improve the stability issues of concern as well or better than SC while simultaneously enabling large scale energy storage [1].…”

This paper summarizes Electromagnetic Transient (EMT) simulation studies using PSCAD/EMTDC undertaken to evaluate the capability and suitability of commercially available large scale Grid Forming Inverters (GFMI) to dampen oscillations in a real bulk power transmission network. Faults and a range of grid voltage oscillation frequencies are tested on GFMI and synchronous condenser (SC) models using single source equivalent network model and comparisons of transient, post fault and oscillatory rejection tests are presented. A critical credible fault in the West Murray Zone (WMZ) was simulated on a wide‐area EMT model of the Australian National Electricity Market (NEM) to show the effectiveness of GFMI in providing system strength services and improving damping of network sub‐synchronous control interactions (SSCI). Two scenarios were examined: Direct replacement of existing centralized synchronous condensers in the WMZ of the NEM, and a decentralized distribution of GFMI in the transmission network (treated as expansion or repowering solution for existing grid following inverter equipped solar farms). Simulation results show that commercially available GFMI are a viable option for improving system strength in a practical transmission system with a high proportion of Inverter Based Resources (IBR).

“…Due to an increasing proportion of Inverter Based Resources (IBR), many utilities, transmission operators, etc. are discovering a wide range of new stability issues in their networks [1]. These issues are generally being collectively referred to under the term system strength or converter driven stability [2,3].…”
