摘　　要：文中提出了一种基于谐振域(RA)的风机控制器参数优化方案,用于刻画在多能量场景下风机与多机系统的模式谐振,并通过优化风机的控制器参数降低潜在的模式谐振风险。首先,建立计及能量场景变化的系统小信号模型。其次,提出确定复平面上可能发生模式谐振区域的RA概念。然后,设计衡量谐振强度以及谐振对模式振荡阻尼影响的谐振强度指标(RSI)。为了避免潜在的模式谐振风险,基于RA和RSI对风机控制器参数进行优化。通过IEEE 39节点模型,验证了所提优化方案可在多能量场景下捕捉模式谐振发生区域,并通过风机控制器参数优化有效避免系统潜在的模式谐振。This paper proposes an optimization scheme for controller parameters of wind turbines based on resonance area(RA)to characterize the modal resonance between wind turbines and multi-machine systems in multi-energy scenarios,and reduce the potential modal resonance risk by optimizing the controller parameters of the wind turbine.Firstly,a small-signal model of the system that takes into account changes in energy scenarios is established.Secondly,the concept of RA is proposed to determine the possible modal resonance region on the complex plane.Then,a resonance strength index(RSI)is designed to measure the resonance strength and the impact of resonance on modal oscillation damping.To prevent potential modal resonances risks,controller parameters of wind turbines are optimized based on the RA and RSI.Through the IEEE 39-bus model,it is verified that the proposed optimization scheme can capture the region where modal resonance occurs in multi-energy scenarios,and effectively avoids potential modal resonance in the system through controller parameter optimization of the wind turbine.
