On June 21, the first grid-side energy storage project in Jiangsu Province, the Jianshan Energy Storage Power Station, was successfully connected to the grid in Danyang, Zhenjiang, marking the official landing of grid-side energy storage project technology application in Jiangsu.
The project is located in the 110 kV Jianshan Substation in Danyang City, with a power of 5 MW and a battery capacity of 10 MWh, covering an area of ​​1.8 acres. It is fully prefabricated and is connected to Jianshan through a 10 kV cable line. 10kV power grid side of the substation.
In September last year, due to the decommissioning of three 330 MW coal-fired units of Jianbi Power Plant, Zhenjiang East Power Grid will face a power shortage situation during the peak of summer electricity consumption this year. As one of the measures to alleviate the power supply pressure during the summer peak season in eastern Zhenjiang in 2018, Jiangsu Electric Power Co., Ltd. combined the advantages of short construction cycle and flexible layout of electrochemical energy storage power stations to implement the construction of energy storage projects in the eastern area of ​​Zhenjiang. As one of the eight grid-side energy storage power station projects in Zhenjiang, the energy power plant has been intensively implemented since it started construction in May.
“Danyang occupies most of the load in the eastern part of Zhenjiang. The grid-connected operation of the Jianshan energy storage power station will not only help alleviate the power supply pressure of Danyang Power Grid this summer, but also provide support for the scale development of renewable energy sources. Regional power grids have peak and frequency modulation capabilities, improve power grid voltage levels, improve power supply quality, and ensure safe power grid operation. "State Grid Danyang Power Supply Company Development and Construction Department Director Zhang Jiangqun introduced.
This energy storage power station is an important application practice of Jiangsu Electric Power to promote comprehensive energy service business in depth. The project is equipped with intelligent network load interactive terminals, anti-island protection and frequency and voltage emergency control systems and other equipment, which can quickly remove faults and ensure the safety of regional power grids. .
