Abstract :This paper presents the evaluation of the sodium-sulfur battery  technology in energy storage and power quality applications. The evaluation of this  technology in the USA was first performed at the Dolan Technology Center of American  Electric Power, Columbus, Ohio. In the first phase of the research, extensive testing and  analyses were performed on a sample module to understand the internal characteristics  and dynamics of the battery, and then performance drivers were defined. A  demonstration project that combines nominal rating of 500kW for 30 seconds of power  quality mitigation and up to 750kWh of peak shaving capacity at a maximum power of  100kW was installed in September 2003 at one of AEP’s Office Buildings in Gahanna,  Ohio. Evaluation so far has shown that the sodium sulfur batteries can solve variety of  power quality problems and provide economical energy storage for a wide range of  power system and energy management applications. AEP and the project partners are  continuing to monitor and evaluate the system.
