Effect of PV panels on the periodic load flow of low voltage distribution grid

Renewable energy resources are a promising energy sources to tackle the climate change and increasing of load demand. The solar energy is the most abundant renewable energy sources. The integration of the photovoltaic panels (PV) with on-grid low voltage (LV) distribution grid changes the power flow and performance of the grid. In this paper, an analysis of power flow and performance of the distribution grid with consideration of PV panels is proposed. open-source distribution system simulator (Open Dss) software is utilized to analyse the power flow of the distribution grid, where the analysis is applied on the connected LV distribution grid which including different types of loads and feeders. The results show that the proposed analysing approach can cope with variable output of the PV panels periodically. The integration of PV generation improves the voltage profile of the buses.
