China Connects 1st Large-scale Flywheel Storage
China connects Dinglun Flywheel Energy Storage Power Station to grid that will provide 30 MW of power with 120 high-speed flywheel units.
Flywheel energy storage is mostly used in hybrid systems that complement solar and wind energy by enhancing their stability and balancing the grid frequency because of their quicker response times or with high-energy density storage solutions like Li-ion batteries .
The operation of the electricity network has grown more complex due to the increased adoption of renewable energy resources, such as wind and solar power. Using energy storage technology can improve the stability and quality of the power grid. One such technology is flywheel energy storage systems (FESSs).
Based on the above main circuit topology, the grid-connected charging and discharging control of the flywheel energy storage system consists of grid-side converter control and motor-side converter control, and goes through three stages: pre-charging, pre-grid connection, and grid operation.
Figure 4.2 shows the main circuit topology of the flywheel energy storage system based on the Back-Back dual PWM converter, which consists of a grid-side LCL filter, a back-to-back dual PWM converter, a permanent magnet synchronous motor, a flywheel rotor, etc.
