The world's first 35kV grid-side high-voltage direct-mounted energy storage power station jointly invested and constructed by Hangzhou Henglong New Energy Technology Co., Ltd. and Zhejiang Shuangcheng Electric Co., Ltd. settled in Zhejiang
The energy storage power station belongs to the high-voltage direct-mounted energy storage on the grid side. As the name suggests, it can be vividly understood as a "charging treasure" "hanging" on the 35 kV public grid. In the past, the energy storage power station used the transformer step-up and step-down type, which has low conversion efficiency and loss. The direct-mounted energy storage can output 35 kV voltage without going through the transformer, which can not only reduce energy loss, but also reduce energy consumption. It can quickly respond to grid demand and achieve a millisecond-level response speed.
The energy storage power station is located in a blank plot between Shangyu 35kV Hongxing Substation and 220kV Daoxu Substation. It consists of 12 prefabricated container cabins, 9 battery energy storage cabins, 1 primary equipment cabin, and 1 secondary equipment cabin. , 1 tool compartment. The battery energy storage unit cabin adopts lithium iron phosphate battery, and the energy storage capacity is 12 MWh, which is equivalent to the power of more than 200,000 ordinary household power banks; its maximum power is 6 MW, which can support about 3,000 household 2-horse air conditioners Work 2 hours at the same time. After it is put into operation, it will significantly enhance the regional power grid's new energy consumption, peak regulation and frequency regulation, and power supply guarantee capabilities.
