On June 30, 2024, marking an important energy construction achievement in the early stage of Zhejiang Province's 14th Five-Year Plan, the Hangzhou Xinneng Taihuyuan Town Energy Storage Power Station in Hangzhou, as the city's first 110 kV energy storage power station, was successfully connected to the grid and put into operation. The project was built by Hangzhou Energy Group with great efforts, covering a large area of nearly 20,000 square meters, with a total investment of up to 257 million yuan. Its highlight is that it has a maximum charging and discharging capacity of 80 megawatts and is equipped with an energy storage system with a total capacity of 160 megawatt-hours. This scale is the leader among the current energy storage power stations in Hangzhou, and it is truly the largest capacity.

The energy storage power station consists of two core functional areas: the energy storage area and the main transformer and SVG area, which work together. The power station is carefully equipped with 32 lithium iron phosphate energy storage battery cabins. These cabins serve as reservoirs for electricity and can efficiently store energy; at the same time, there are 16 cabins that integrate current conversion and boosting functions to ensure flexible conversion and transmission of electric energy. An advanced energy management system is integrated into the power station. It is like the intelligent brain of the power station, precisely controlling each link.

In the dynamic balance of power supply and demand, the system shows excellent flexibility. When the power grid is in the low power consumption period, that is, when the power demand is relatively low, it will automatically start and store the excess power; and when the peak power consumption comes and the power demand surges, the stored power can be quickly released back to the power grid, effectively alleviating the power supply pressure and achieving the goal of peak shaving and valley filling. In this process, it also plays an important role in stabilizing the power grid frequency and ensuring the stable operation of the large power grid.Editor/Zhang Liyuan
