Design optimization of advanced-battery energy-storage systems for utility networks

Technical Report ·
OSTI ID:6098758
High-performanced advanced batteries are under development in both the United States and Japan for use in load leveling on utility networks. A battery energy storage system for load-leveling is basically composed of three components: strings of batteries, a power conditioning system, and a control and power distribution management system. This type of system must be capable of fulfilling the unique requirements of each plant site. Among the requirements that vary are the size of the storage capacity, the users' demand patterns, and both environmental and cost considerations. The selection of the power conditioning system is particularly influenced by the local requirements. The primary function of the power conditioning system is to convert and transfer off-peak electric energy to stored energy and to convert and retrieve the stored energy when it is required. In addition, the power conditioning system provides protection for the battery string and the electrical components by preventing inadvertent lightning surge current and catastrophic shorting. In addition, additional engineering systems are required to cope with voltage fluctuations and harmonic current associated with the demand patterns and local weather patterns such as frequency of lighting that are specific to each site.
