System Strength-Constrained Scheduling with Switchable Grid-Forming and Grid-Following Generation Resources
The episode discusses a paper developing a framework to optimize Inverter-Based Resource (IBR) operating behaviors while ensuring system strength. The authors convert this complex problem into a solvable Mixed-Integer Semi-Definite Programming (MISDP) problem using an LMI reformulation, which is then solved with standard MILP solvers. This provides a systematic tool to analyze how system strength constraints affect IBR operation and mode switching.
