The penetration of Distributed Energy Resources in power generation has increased considerably during the last two decades. Low voltage grids are configured as microgrids in which the most common energy resources are photovoltaic systems and wind turbines, usually complemented by energy storage and/or backup generation. This paper presents the behavior of two microgrid systems in islanding mode. The first system consisted of a wind turbine, a diesel generator and a load, while the second system consists of the same components as the first system but a PV – battery system with an inverter is also inserted. The voltage and frequency characteristics of both scenarios are being examined. The main findings indicate that an absence of energy storage, such as a battery, leads to excessive backup generation capacity requirements, while the presence of an inverter after connecting the PV–battery unit has a strong effect on the power quality.
