The increasing number of distributed generation units has led to the development of microgrids, to which the distributed generators are commonly interfaced by means of a voltage-source inverter (VSI). When the microgrid is operating independently of the power system, i.e., in islanded mode, two levels of control can be distinguished for these VSIs: power control and voltage control (frequency and...
Frequency response analysis is a well established system identification method. In this paper, a simple and efficient method based on the classical Transfer Function Analyzer (TFA) technique is implemented for system identification. The novel algorithm has been called Switch-Mode-TFA. The originality of the proposed approach consists of: i) using a chirp TFA test input instead of a pure sine function,...
