Simulation of the Residential Photovoltaic System Expansion Impact on the Voltage Profile

Distributed Generation (DG) can provide voltage improvement but also can cause over-voltages in radial distribution networks. This paper investigates an impact of the residential photovoltaic system expansion on the voltage profile of the observed feeder. Model of the expanded photovoltaic system and local distribution network is made in DigSILENT Power Factory software. In order to investigate if voltage limits are violated, voltage profile analysis is performed for different levels of distributed generation and residential consumption. Simulations are repeated when standard transformer is replaced with OLTC transformer.
