Calibration and sensitivity analysis of upper level VSC-HVDC controls

High Voltage Direct Current (HVDC) interconnections have seen an increased rate of deployment, in particular to exploit distant renewable energy sources. In order to design and understand their behavior, including their effect on the overall network, different computer tools are used for modeling and simulation. This approach results in several challenges in modeling and simulation consistency, particularly for HVDC systems. In this paper, to address some of these issues, the standardized Modelica modeling language is used to model a VSC (Voltage Source Converter)-based HVDC and its upper-level controllers, suitable for dynamic analyses. The use of Modelicatools that support the FMI standard for model-exchange allows to utilize the model in different environments. In this work, the FMI standard is used to import the VSC-HVDC model into the RaPId toolbox environment, thus allowing to calibrate the VSC-HVDC phasor model against reference waveform generated from its corresponding EMTP-RV model. Model calibration is carried out through parameter identification and a sensitivity analysis is carried out to interpret the identification results.
