Performance analysis of sodium sulfur battery in energy storage and power quality applications

Bu makale sodium sülfür bataryalarının enerji depolama ve güç kalitesi uygulamalarındaki performanslarını değerlendirmektedir. Bu yeni teknolojinin teknik değerlendirmesini Amerika'da ilk olarak Dolan Technology Center of American Electric Power, Columbus, Ohio, araştırma grubu gerçekleştirmiştir. Araştırmanın ilk safhasında, bu ileri batarya sisteminin iç karakteristiklerini ve dinamiklerini tanıyıp anlamak ve daha sonrada performans parametrelerini belirlemek üzere test ve analizler yapılmıştır. Sodyum sülfür bataryalarının, 30 saniye süreli 500 kW'a kadar güç kalitesini iyileştirme ve 100 kW'da 720 kWh 'lik enerji kapasiteli tepe kırpma yeteneklerinin birleştirildiği bir dizaynı test etmek üzere yeni bir sistem Eylül 2003 'te AEP 'a ait bir ofis binası için kurulmuştur. Şu ana kadarki testlerden elde edilen sonuçlar, sodyum sülfür bataryalarının geniş bir yelpazedeki güç kalitesi problemlerini çözdüğünü ve enerji yönetimi uygulamalarında ekonomik bir alternatif teknoloji olduğunu göstermiştir. Sistemin izlenmesi ve değerlendirilmesi sürmektedir.

Sodyum-sülfür bataryaların enerji depolama ve güç kalitesi uygulamalarındaki performans analizi

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 l00 kW 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.
