Abstract: Wind energy is a compromising energy source which would contribute significantly toward alleviating the energy crisis caused by the limited amount of the existing fossil fuel. The main limitation in making it of wide-spread application is that wind energy is often discontinuous and variable. To connect this intermittent energy source directly to existing electrical grid may cause unacceptable network voltage and/or frequency variations. As a way to overcome the problem, a battery energy storage scheme has been considered in previous investigation, so that it can act like a buffer for the wind energy harnessed. The battery energy storage system designed in an early works is incorporated within an unified power flow controller (UPFC). The purpose is to enhance network power quality, system reliability and renewable energy harnessing. In this design, two batteries are operated in turn. These battery banks are denoted as in-service battery and stand-by battery respectively. Under normal operating condition, the stand-by battery should be full charged before the in-service battery needs to be taken off line for a re-charge. To make the scheme viable, battery power capacity should be minimized. Accordingly, the main aim of this project is to design a computational method to determine the optimum power capacity.
