Voltage Support With PV Inverters in Low-Voltage Distribution Networks: An Overview
IEEE Journal of Emerging and Selected Topics in Power ElectronicsLarge solar photovoltaic (PV) penetration using inverters in low-voltage (LV) distribution networks may pose several challenges, such as reverse power flow and voltage rise situations. These challenges will eventually force grid operators to carry out grid reinforcement to ensure continued safe and reliable operations.

Voltage Support Scheme for Low Voltage Distribution Grids Under Voltage Sags [PDF]
2019 IEEE Milan PowerTech, 2019 A grid-connected power electronics based distributed generator can act as an active element by providing support to the grid under various disturbances. In this paper, a voltage support scheme dedicated for distributed generators installed in the low voltage distribution network is proposed.
