Modelling and Simulation of Energy Storage System for Grid Connected Wind PV System

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.
