The grid connection project of Dalian flow battery energy storage peak-shaving power station started

On September 16, the 220kV transmission project of the Dalian Flow Battery Energy Storage Peak-shaving Power Station National Demonstration Project was officially launched. At present, the project is the world's largest chemical energy storage power station. The Dalian flow battery energy storage peak-shaving power station stores electric energy in an electrolyte tank. During the low electricity consumption period, the abundant electric energy is stored. When the electricity consumption peaks, the stored electric energy is output and used to reduce electric energy waste. The service life is 20 years. The project is located in Xigang District, Dalian City. It is the first large-scale chemical energy storage national demonstration project approved by the National Energy Administration and the only chemical energy storage peak shaving power station in my country. The construction scale reaches 200 MW/800 MWh. With an area of u200bu200b36519 square meters, construction started in November 2016, and it is planned to be completed and put into operation in December this year, with a total investment of 3.8 billion yuan. The project adopts the all-vanadium flow battery energy storage technology independently researched and developed in China with independent intellectual property rights. It is suitable for high-power and large-capacity energy storage, with good safety, long cycle life, fast response speed, high energy conversion efficiency, and environmental protection. And other advantages. Dalian is rich in nuclear power and offshore wind power resources, and thermal power is also dominated by thermal power. The peak shaving pressure of the power grid is particularly prominent during the heating period in winter. After the project is completed, it can play the dual purpose of peak shaving and valley filling, improve the peak-shaving capacity of Dalian power grid and the reliability of power supply in southern Dalian, ensure the safe and economic operation of the power grid, improve the power supply structure of the Liaoning power grid, promote wind power development, and promote energy storage technology Application and development. At the same time, after the battery energy storage station is put into operation, it will improve the current situation of the weak connection between the Dalian Southern Power Grid and the main grid due to the geographical location. When encountering severe weather or special circumstances, it can act as an uninterruptible power supply device to supply important loads. Uninterrupted power supply, and as an auxiliary power source for the black start of regional thermal power units, improving the reliability of power supply to the southern power grid of the urban area.
