The voltage rise caused by PV power infeed is one of the main network constraints limiting the PVpenetration in distribution networks. In this paper a local voltage control approach for photovoltaic inverters based onreactive power management is proposed and investigated into detail. Through a parametric study, various invertersettings are considered and compared for a real medium voltage network with a high PV penetration level and forwhich a demonstration is planned within the project MetaPV [1] [2]. The purpose of this work is to investigate thesuitability of such control concepts to compensate the voltage rise caused by the PV power infeed and to providesome guidance on the adjustment of the settings of such control mechanisms. In order to assess the performance ofthe control concept with different settings, extensive load flow simulations have been performed for a voltagedependantreactive power control (Q(V) characteristics) on the basis of 15 minutes profiles. As a result, voltage timeseriesover a period of one year are obtained for each case and analysed into details. Apart from the voltage profiles,other features such as network losses and reactive energy import have been quantified since they are also ofnoticeable importance for network operators. The simulation results show that suitable settings are necessary in orderto maintain the voltage within the prescribed limits. A comparison between the considered cases shows that reactivepower control Q(V) with a power factor down to 0,9 is necessary in order to achieve satisfying results. The use of adead-band is recommended for the voltage dependant reactive power control in order to limit the losses and reactiveenergy import.
