Impedance is an important parameter to analysis the stability of microgrid. Stability criteria have been developed in terms of source and load impedances for both dc and ac systems, and it is often helpful to have techniques for impedance measurement. First, the theoretical impedance of microgrid is calculated in this paper. Second, a new method of impedance measurement for microgrid is introduced...

Harmonic impedance is the important parameter to analyze the stability of power system. In the microgrid, due to the existence of power converters with constant power characteristics which may result in negative impedance and thus decreases the system stability, harmonic impedance measurement is also of great significance. In this paper, the droop control strategy for parallel inverters in microgrid...
