基于模糊卡尔曼滤波和改进滑模控制的风电场飞轮储能控制策略
Control strategy of FESS in wind farms based on fuzzy Kalman filter and improved sliding mode control
摘要
Abstract
Installing a certain capacity of flywheel energy storage system(FESS)at the grid connection of wind farms can effectively smooth the grid-connected power and improve the grid-friendliness of wind farms.To improve the power response speed of FESS and enhance the smoothing effect of wind power fluctuation while avoiding overcharge/overdischarge of FESS,this paper proposes a control strategy for FESS based on a fuzzy Kalman filter and the improved sliding mode control(SMC).The Kalman gain is adaptively adjusted according to the real-time speed and power of FESS.The difference between the filtering result and the wind farm output power is used as the input of the SMC to realize the power control of FESS.The simulation results show that the control strategy proposed in this paper has good dynamic response characteristics and the wind power can be effectively smoothed,thus meeting the requirements of grid connection.The flywheel speed is kept within the limit during the smoothing process,which extends the service life of FESS.关键词
