Abstract :
In this paper, a grid connected hybrid power system comprising wind and solar based renewable energy sources RERs is proposed. As these RERs are intermittent and random in nature, so a backup source is needed for smoothening the fluctuations in RERs output power. Battery energy storage BESS is proposed for this purpose. The electrical grid of the example represents a typical Utility distribution system. It consists of a 120-kV transmission system equivalent supplying a 25-kV distribution substation. Several feeders are connected to the 25-kV bus of the substation. One of them supplies the power to a community that owns the PV farm and an energy storage system. The grounding transformer connected at the 25-kV bus provides a neutral point and limits the overvoltage on the healthy phases during a single-phase fault. Its zero-sequence impedance is three times the value of the grid positive sequence impedance.
