基于状态重构的构网型风机与储能系统联合频率支撑控制策略
Frequency Response Coordinated Control Strategy Between Grid-forming Wind Turbine and Energy Storage Based on State Reconstruction
摘要
Abstract
It is difficult to assess the frequency modulation ability of a wind power and energy storage system,which is affected by the operating status,and the power generation efficiency is worse.Therefore,this paper proposes a frequency response coordinated control strategy between wind power and energy storage.Based on the current state of charge(SOC)of the energy storage system,the frequency modulation capability is reconstructed,and then the equivalent active reserve demand for wind power is evaluated.The wind power reserve power level and operation strategy are designed.The grid-forming wind turbine with natural inertia response capability combined energy storage adaptive inertia control is used to achieve fast active power support for the wind storage joint system,and the wind storage joint system participates in primary frequency regulation based on frequency disturbance types and current state characteristics.Simulation analy-sis verifies the accuracy and effectiveness of the proposed control strategy,which can provide effective active power frequency supports under the condition of sudden load increasing or decreasing.关键词
