摘要

The penetration of photovoltaic (PV) systems has been growing rapidly in the Hungarian distribution grids recently. Although, Hungarian grid codes do not involve regulations which can mitigate the expected negative effects of the PV generation. The purpose of this paper is to investigate how PV systems should take part in the voltage regulation with the use of cosφ(P) reactive power control method. In order to achieve this, a low-voltage distribution grid model is created, which is representative for the Hungarian situation and based on real grid parameters. This model is suitable for investigating the negative impacts of the active power injection of PV systems. For that purpose, scripts were written and steady-state simulations were executed with the use of Digsilent Programming Language. The results show that the network hosting capacity is largely limited, if the PV systems do not take part in the voltage control due to the significant voltage rise. The hosting capacity can be considerably increased with the use of cosφ(P) reactive power control strategy. Nevertheless, the parameterization of the method has a huge impact on the simulation results.
