摘要：
A new method for on-line grid impedance estimation is presented in the paper. It is based on an algorithm that requires no measurements from other buses. What is more, in normal operation it does not need to inject any current to the grid at the point of common coupling as it common in active methods for impedance estimation. The paper includes a mathematical derivation of the key equations, simulation results for a simple test system as well as performance evaluation. Laboratory tests are ongoing.
