- AbstractThis paper presents an energy management strategyfor a hybrid energy storage system for a wind dominated remotearea power supply (RAPS) system consisting of a doubly-fedinduction generator (DFIG), a battery storage system, a supercapacitor,a dump load and main loads. Operation of a batterystorage system is coordinated with a supercapacitor with a viewto improve the life span of the battery. In this regard, the batterystorage system is connected to the load side of the system whilethe supercapacitor is connected to DC bus of the back-to-backconverter of the DFIG. The operation of the hybrid energystorage system is coordinated through the implementation of anenergy management algorithm (EMA) which is developed with aview to reduce the depth of discharge (DOD) and ripple contentof the battery current. The dump load is connected to the loadside of the system which utilises the power in situations thatcan not be handled via energy storage system. In addition, anovel coordination method has been proposed to coordinate thepower flows among all system components with a view to regulatethe power flow and thereby ensuring the robust voltage andfrequency control on the load side and capturing the maximumpower from wind
