Models That Reflect How IBRs Actually Behave
Accurate inverter-based resource models are the foundation of every credible grid study. We build, calibrate, and validate IBR models - from generic to manufacturer-specific - against measured field data and EMT simulation.
Every model benchmark-tested against disturbance recordings before delivery
Facing These IBR Modeling Challenges?
Model fidelity, not just model delivery
Generic or UDM - models must match reality
Whether we're working from WECC generic templates or an OEM user-defined model, every model is calibrated and validated against measured plant data before delivery.
No model leaves unvalidatedManufacturer-Specific
We work with OEM user-defined models (UDMs) and black-box models - not just WECC generics.
EMT + Positive Sequence Models
Consistent positive-sequence models across planning and stability tools, paired with detailed EMT simulation for dynamic verification.
PSS/E · TSAT · PSCADNERC MOD-Ready
Validation reports formatted for MOD-026 and MOD-027 submission to the transmission planner.
IBR modeling capabilities
Dynamic Model Development
Build positive-sequence dynamic models for solar PV, wind (Type 3 & 4), and BESS - generic WECC or manufacturer UDM.
EMT Model Construction
Detailed electromagnetic transient models in PSCAD capturing converter control loops, PLL dynamics, and current limiters.
Model Parameter Tuning
Systematic calibration of controller gains, time constants, and limiter settings to match measured plant behavior.
Disturbance Record Analysis
Process and interpret PMU, SCADA, and fault recorder data to extract benchmarking waveforms for model comparison.
NERC MOD-026 / 027 Validation
End-to-end model validation studies with compliance documentation ready for transmission planner review and NERC filing.
Model Uncertainty Assessment
Sensitivity studies quantifying how parameter uncertainty affects planning study outcomes - supporting risk-informed grid decisions.
IBR types we model and validate
Utility-Scale Photovoltaic
Full plant model from DC array through inverter controls and plant-level reactive power control to the POI. We work with UDMs from all major inverter OEMs as well as WECC generic models.
Type 3 & Type 4 Wind
DFIG and full-converter wind turbine models capturing aerodynamic, mechanical, and electrical converter dynamics. We work with UDMs from all major wind turbine OEMs, including aggregated plant models.
Battery Energy Storage (BESS)
Bi-directional inverter models with state-of-charge constraints, fast frequency response, and grid-forming capability. Covers standalone BESS and hybrid solar + storage configurations across all major BESS OEMs.
Power Plant Controller (PPC)
We develop UDM source code for several PPC and inverter vendors - giving us model-level insight that goes beyond parameter tuning. Our engineers work directly in the model internals, enabling faster calibration, deeper validation, and more accurate representation of plant-level control behavior in grid studies.
