Experimental study on voltage dependent reactive power control Q(V) by solar inverters in low-voltage networks

This paper presents the results of an experimental study on voltage dependent reactive power control Q(V) by solar inverters in low-voltage networks. The project´s intention is a neutral investigation of the stability of a V-Q control in low-voltage networks. The results of this study showed that a voltage dependent reactive power control Q(V) by solar inverters in low-voltage networks will not cause any stability issues. Furthermore, this paper will comprise recommendations about the parameterization of the V-Q control and about some important standardization issues.
