Inverter-Based Resources (IBRs)
Objective
Distribution planning support and Interconnection Requirements Study (IRS) for solar PV and battery system.
Approach
We created a simplified model:
- A customized tool
- Evaluated smart inverter models and transient voltage
- Assessed islanding risk
Outcome
We created simplified feeder models in PSCAD and customized proprietary tools to the utility case. Prior to incorporating it to the feeder model, we evaluated smart inverter models. We assessed the risk of unintentionally islanding and evaluated transient voltage due to ground fault and load rejection scenarios.
