Abstract :
A prototype 250 kVA modular battery energy storage system was developed and tested for utility peak-shaving applications-in a cooperative Department of Energy, industry, and utility project. The system consists of battery- and converter-integrated modules with AC terminals. Data on the system´s energy capacity, power quality, power factor, auxiliary power, thermal regulation, speed of response, and islanding and other protective measures are presented. A simple method of identifying the presence of a defective battery was revealed during the test period
