考虑频率二次跌落和风速差异的风储联合持续调频控制策略
Wind Turbine-Energy Storage Coordinated Sustained Frequency Regulation Control Strategy Considering Secondary Frequency Drop and Wind Speed Variation
摘要
Abstract
To improve the sustained frequency support capability of wind farms and address the issue of wind turbines being unable to participate in grid frequency regulation for extended periods at maximum power points,this paper proposes a wind turbine-energy storage coordinated sustained frequency regulation control strategy considering secondary frequency drop and wind speed variation.Firstly,based on the frequency regulation demand of wind farms and the dynamic characteristics of wind turbines,a control strategy for coordinated frequency regulation between individual wind turbines and energy storage system is proposed,which extends the sustained frequency regulation time of wind farms and effectively suppresses secondary frequency drop.Secondly,a method for setting the reserve frequency regulation power of energy storage is designed,enabling dynamic adjustment of the reserve power based on the steady-state power of wind turbines.Finally,considering wind speed variation among wind turbines within a wind farm,energy storage output power is allocated to coordinate the participation of wind turbines under different wind speed conditions in frequency regulation.Simulation results verify that the proposed method significantly extends the frequency regulation time of wind farms,effectively coordinates the participation of wind turbines in frequency regulation under varying wind speed conditions,and successfully suppresses secondary frequency drop.关键词
