Advanced Energy Verified
Confidence in every connection
Electricity demand is increasing. inverter-based resource (IBR) penetration is growing — and getting more complex. Standards are evolving. And the lights need to stay on. When models don’t reflect what’s on the ground, and when what’s on the ground doesn’t conform to requirements, the consequences can be severe.
Third-party IBR verification through AE Verified shows a clear commitment to grid reliability and provides peace of mind that your facilities will perform safely, predictably and in alignment with agreements.
Grid reliability necessitates third-party verification of every interconnected inverter-based resource (IBR). As the trusted choice for reliable interconnection, we’ve overseen the quality assurance of more than 600 IBR facilities.
Real-World Issues
Inverters and relays are often configured with improper voltage and frequency trip setpoints. These settings determine when equipment trips offline during grid disturbances; if they’re wrong, facilities may disconnect unexpectedly for minor disturbances or fail to respond as desired during faults.
Risks:
- System instability
- Cascading outages
- Non-compliance with IEEE 2800 and operator standards
Power plant controller (PPC) settings aren’t aligned with the facility’s voltage schedule requirements specified by the transmission operator. Some report incorrect reactive power flow or breaker status. Voltage control is essential for grid stability, and mismatches can lead to poor coordination and blind spots for operators.
Risks:
- Voltage collapse during peak or fault conditions
- Reduced system resilience
- Operator response delays
Substation equipment specs and single-line diagrams often contain errors. Many IBR plant dynamic models submitted to transmission operators are incorrect. Operators rely on accurate models to simulate grid behavior and plan for contingencies.
Risks:
- Fault propagation
- Equipment damage
- Delayed approvals and costly rework
Getting IBR facilities online requires coordination among many parties. Input from experienced independent verification experts helps ensure these sites stay online when needed most.
