Dynamic Modeling & Tuning Services
Ensure compliance & simulation accuracy
ETAP is a leader in grid compliance solutions and provides services to build, simulate, and tune control systems for conventional & renewable generating systems. We understand the need for generation facility owners or operators to maximize production without compromising system security while fulfilling their grid interconnection obligations.
We can assist your business with grid compliance and dynamic modeling when connecting to the grid. We also help with updating networks and offer services to businesses looking to connect renewable technologies to their national grid.

ETAP engineers specialize in validation studies, field testing, and reporting. ETAP is committed to helping our clients meet the grid code compliance standards and other regional requirements that are continuously monitored and enforced.
Equipment dynamic models Control system transfer functions for exciters and governors can be used from the existing library in ETAP or created using the User-Defined Dynamic Model or utilizing vendor-specific dynamic link libraries (DLL).
User-Defined Dynamic Model
User-Defined Dynamic Model (UDM) builds and compiles the control block diagrams used by the Transient Stability and Generator Start-Up modules of ETAP. UDM models can be used in multiple machines with independent self-testing for load rejection, load acceptance, and terminal bus faults for validation of models and their dynamic behavior.
ETAP Engineering Services team can easily and quickly customize your models and save you time on your projects. Having a dynamic model gives you the flexibility to update or revise existing models leading to a shortened development life cycle.
Dynamic Model Parameter Estimation & Tuning Services
Compare recorded actual generator response from the system and compare it against the response from a simulation in ETAP. Parameters for these control systems in ETAP are then adjusted to match the response characteristic available from the actual device.
Grid Compliance Studies
We specialize in ensuring that wind farms/renewable generation are grid compliant. ETAP has provided grid compliance services to multiple generating units, including wind and solar power plants in the US and other countries. We have helped clients successfully comply with various standards required by NERC, regional reliability councils, including ISOs and regulatory entities in many countries.

- Load flow and reactive power curves
- Fault ride through studies
- Frequency response and dynamic analysis
- System modeling and data capture
- Harmonic studies of network and generation technologies
- P28 voltage dip and flicker studies
MOD-025-2: Verification of Generator Active and Reactive Power Capability
Verify generator gross and net active and reactive power capability for steady-state planning models used for system reliability assessment. This requirement applies to both conventional and renewable energy resources, such as wind and solar farms.
MOD-026-1: Validation of Excitation System Model or Plant Voltage/Var Control Functions
Excitation system models, including the power system stabilizer model for conventional generators, or plant volt/var control functions for wind and solar farms, are validated through field testing. Their voltage control behavior should be accurately represented in dynamic simulations when assessing system reliability.
MOD-027-1: Validation of Turbine/Governor Model or Plant Active Power/Frequency Control Functions
Turbine and governor models, including load controller for conventional generators, or plant active power/frequency control functions for wind and solar farms are validated through field testing. Ensure that their responses to system frequency variations can be adequately represented in dynamic system simulations.
