  3. Electrical measurements
    The accuracy of the measurement chain of the UVRP components is verified
  4. Validity of UVRP-generated files format and content
    The presence, correctness and quality of information in the system-generated (UVRP) files are checked
  5. Remote verification of the presence of primary control
    The logic in the algorithms used in the 60870-5-104 communication with TERNA, and the correctness of the protocol are validated
  6. Energy check
    Using particular frequency profiles, The amount of energy calculated by the model is compared to the actual values measured by the turbine, so as to validate the model.
