The method includes injecting at least one chirp signal into the three-phase AC system, and collecting at least one response to the at least one chirp signal. The method further includes transferring the at least one response from abc coordinates to dq coordinates. At least one impedance is calculated based on the at least one response to the at least one chirp signal.application/pdfenPatenthttp://pimg-fpiw.uspto.gov/fdd/55/185/096/0.pdf13953981G01R29/26G01R27/02G01R27/169618555
