Simulation of Secondary Frequency Modulation Process of Wind Power
Based on MATLAB/Simulink simulation, the role and effect of secondary frequency modulation assisted by Flywheel Energy Storage System (FESS) in regional power grid with
Throughout the process of reviewing the existing FESS applications and integration in the power system, the current research status shows that flywheel energy storage systems have the potential to provide fast and reliable frequency regulation services, which are crucial for maintaining grid stability and ensuring power quality.
Since flywheel energy storage is used for power smoothing in wind power systems, the charging and discharging of flywheel energy storage and the fluctuating state of wind power are shown in the two-dimensional plane.
The high-frequency component of the wind power output power data accounts for less than 10 % of the total energy. Therefore, this study selects a 100 MJ/0.3 MW flywheel energy storage device for a 30 MW wind farm, and the rated speed of the flywheel is 4000 r/min. 2.2. Energy storage systems
Secondly, a mathematical model of the flywheel energy storage system applied in the model predictive control algorithm is proposed, and the model predictive control algorithm is used to configure the flywheel energy storage device to achieve a smooth output power of the wind farm.
