According to the energy storage demands of short term and high frequency in the wind solar new energy grid, this paper focuses on the demonstration application researches of the MW flywheel array in the wind solar energy storage field. In this paper, the system composition and topological structure of the flywheel array are firstly introduced as well as the working principle. On this basis, the system design of the flywheel energy storage array is provided. Finally, the real experimental tests by using the actual flywheel array system is developed in Tianjin and Qinghai wind solar energy storage field. After thousands of the charging-discharging cycle experiments, it can be shown that the designed flywheel system stays stable and reliable. Owing to the significant advantages, the total power, capacity and response characteristics can meet the requirements of the new energy frequency adjustment process.
