Abstract
This paper deals with stability and accuracy issues that occur in Power Hardware-in-the-Loop experiments (PHIL). Firstly, based on the Bode stability criterion, an analytical investigation of the stability margins of a PHIL simulation without using approximations for the time delay is presented. Then, the proposed analysis is used for the extension of existing methods, which results in the accurate and justified choice of their parameters and, thus, the improvement of the accuracy and stability in PHIL experiments. Finally, the calculated parameters of the feedback filter method are compared with the real parameters derived from the execution of PHIL experiments.
