Improving the power quality and power reliability by energy storage technology - The practice of SMEPC

The electrical energy storage technology has already become an important technical method to level the load, suppress load fluctuation of electrical network and to guarantee the specific user´s electricity reliability. In Hangtou 35kV substation in Shanghai, which also is an energy storage experiment yard, we arrange a 100kW × 8h sodium sulfur battery, a 100k × 2h lithium-ion battery and a 100k × 1.5h Ni/MH battery energy storage systems.
