I. Introduction
PV-installations in low voltage networks lead to a voltage rise at times with high feed-in and low consumption. This voltage rise could result in a violation of the voltage quality requirements and therefore requires a limitation of the photovoltaic (PV)-penetration in low voltage networks [1]. There are several strategies implemented in inverters to reduce voltage rise due to feed-in in medium and low voltage networks based on reactive power control. Considering the different R/X ratios of MV and LV networks these strategies generally result in higher voltage reductions in MV networks compared to LV networks (especially for underground LV cables [2]). In the recent years, several reactive power control strategies were developed and tested in the field [3]–[5]. Also reactive power control and active power curtailment can be coordinated to reduce voltage rise caused by infeed of DER in LV-networks [6], [7].
