It adopts the all-vanadium liquid flow battery energy storage technology independently developed by the Dalian Institute of Chemical Physics. The project is expected to complete the grid-connected commissioning in June this year.
The power station is the first phase of the "200MW/800MWh Dalian Flow Battery Energy Storage Peak Shaving Power Station National Demonstration Project". It is the first 100MW large-scale electrochemical energy storage national demonstration project approved by the National Energy Administration.
Vanadium redox flow batteries (VRFBs) can effectively solve the intermittent renewable energy issues and gradually become the most attractive candidate for large-scale stationary energy storage. However, their low energy density and high cost still bring challenges to the widespread use of VRFBs.
These data were then incorporated into the development of the equivalent circuit model, ensuring its precision and reliability in predicting the performance of the vanadium flow battery. According to the simulation results, there are no vortexes and near-zero velocity zones in the flow field inside the cell.
Through this analysis, it was determined that the PEM had a uniform structure, enabling an accurate model of the battery’s behaviour. These data were then incorporated into the development of the equivalent circuit model, ensuring its precision and reliability in predicting the performance of the vanadium flow battery.
The project is expected to complete the grid-connected commissioning in June this year. After the completion of the power station, the output power will reach 100 megawatts, and the energy storage capacity will reach 400 MWh, which is equivalent to storing 400,000 kWh of electricity.
