A Framework for Sensitivity Analysis of Real-Time Power Hardware-in-the-Loop (PHIL) Systems

Power hardware-in-the-loop (PHIL) simulation leverages the advanced real-time emulation based technique to carry out in-depth investigations on novel real-world power components. amplifiers, sensors, and signal conversion units interfaces (PI) incorporate physical hardware systems platforms into PHIL setups. However, employment of any interfacing inevitably introduces disturbances such as sensor noise, switching harmonics, or quantization noise systems. To facilitate quantitatively analyzing assessing impact external systems, a framework for sensitivity analysis setups has been developed in this paper. Detailed modelling principles related inherent relationship between transfer functions stability criteria are elaborated along with theoretical experimental validation. Based concept, accuracy assessment methods employed quantify generic criteria. Moreover, passive load converter-based applied results presented characterize demonstrate applicability proposed framework.
