FGI helps Zhejiang's largest energy storage power station connect to the grid smoothly

Recently, Zhejiang Wuyi Xinyuan energy storage Power station booster station successfully connected to the grid, marking Zhejiang Province's largest single installed capacity of grid side energy storage project officially put into operation.

1.project context

With a total installed capacity of 200MW/400MW, Xinyuan Energy storage Power Station is the largest energy storage project in Zhejiang power grid and has broad application prospects. The power station adopts liquid-cooled modular storage technology and uses lithium iron phosphate battery storage system, including battery packs and variable current booster box, with a total investment of 800 million yuan.

The construction of the "14th Five-Year Plan for New Energy Storage Development in Zhejiang Province" and the 2024 "List of thousands of trillion Projects for expanding effective investment in Zhejiang Province" is of great significance to promote high-quality development, and is also a major measure for Zhejiang power grid to build a new energy system and ensure a new generation of energy and power supply.

Xinyuan energy storage power Station adopts electrochemical energy storage technology, which has the characteristics of fast frequency modulation rate, high precision and short-time power throughput, etc., which can effectively alleviate the intermittedness and randomness of new energy sources such as wind and solar complementation on the grid, and provide a more abundant means of peak regulation for the grid, which is of great significance for China's energy clean and low-carbon transformation, coping with extreme events, and ensuring energy security.

2.FGI schem

FGI can assist the energy storage power station through two 20MW SVG devices to achieve reactive power support for the energy storage power station, and can effectively improve the power supply quality of the energy storage power station to ensure the safe operation of the grid.

SVG collects the voltage and current signals of the power grid, calculates the reactive power and power factor of the system, and dynamically adjusts the system, so as to keep the system's voltage, voltage and other parameters within the set range, and realize the smooth and accurate adjustment of the system.

SVG products have standardized interfaces, can be connected with the station integrated automation system, can be operated remotely, and can upload the working status of the equipment and fault information in real time, to achieve a high degree of automation and integration.
