Energy storage control system joint debugging

What is a flywheel energy storage system (fess)?

The flywheel energy storage system (FESS) cooperates with clean energy power generation to form “new energy + energy storage”, which will occupy an important position among new energy storage methods.

Can a flywheel energy storage unit control frequency regulation?

To enhance the frequency regulation capability of the FESS, some frequency regulation control strategies for wind-power systems with a flywheel energy storage unit have been proposed ( Peralta et al., 2018, Jia et al., 2022, Yulong et al., 2022, Yao et al., 2017 ).

Can fess be used as a new form of energy storage?

The feasibility of using the FESS based on a six-phase PMSM for the practical application of frequency modulation of wind power was validated by simulation results, which simultaneously validated the practical significance of FESS as a new form of energy storage in new energy generation.

How does fess work in a wind turbine?

The excess power output by the fan will charge the FESS, which stabilizes the output power and also fully utilize the excess power. When the output power of the wind turbine is insufficient, the FESS will discharge to offset the power input to the grid and stabilize the power. A flowchart of the frequency modulation process is shown in Fig. 10.

Can energy storage solve a rigid energy demand?

However, clean energy is having trouble meeting the needs of rigid energy demands due to its randomness, intermittency, and unpredictability, so energy storage is currently being considered to solve this incompatibility.

What happens when fess switches between charging and discharging state?

When the FESS switches between the charging and discharging state, the transition of torque is smooth, so it does not cause sudden fluctuations in power. Fig. 12. The output power after the frequency modulation. Fig. 13. The speed of the flywheel rotor.
