摘要

With the continuing incorporation of renewable electrical energy sources such as solar panels at residential buildings, office complexes, and industrial firms, utilities are recognizing the importance of implementing a rugged, reliable energy storage system to handle the excess power. This paper discusses large-scale battery banks as one of the major sources of stored energy within an electrical utility’s system that can be used in combination with solar panels or by themselves. This paper attempts to understand and explain the complexities of distributed energy storage from a utility perspective. It describes newer techniques to measure battery banks’ performance in a distribution system. It also explains new trends to improve battery banks’ performance. A method of uniform charging across all cells in a bank to extend life expectancy will be presented. A robust control algorithm for battery charging and discharging at the individual cell level, with various safety features built in, will be explained. Additionally, potential use of a battery energy storage system combined with a DC link capacitor of power converters and static compensators will be discussed.
