Feasibility study of Battery Energy Storage System with power quality support in Malaysia

The paper describes potential of Battery Energy Storage System (BESS) in Malaysia focussing in particular the use of Advanced Sodium Sulfur (NAS) Battery. NAS-BESS is considered because of its special characteristics and capability that enables hybrid use of load levelling and power quality improvement. Various applications of BESS will be described together with case studies of potential benefits to utility and customers in Malaysia. Even though the use of energy storage system is not yet critical in Malaysia, this paper will attempt to present analysis and potential benefits of BESS applications for TNB and its large power users.
