随着配电网络大规模接入，谐波污染呈现出高密度、分散和网络化特征，传统点对点谐波控制方法无法满足要求，对此提出一种兼顾配电网多谐波源治理成本和效果的基于谐波发射权重和灵敏度分析的有源滤波器双层优化配置方法。首先，建立谐波发射权重模型，通过谐波治理灵敏度分析，构建以电压检测型有源电力滤波器（voltage detection activepower filter,VDAPF）接入点为参照的谐波防治区划；其次，采用两层优化模型对其进行求解，外层以VDAPF最小运行成本为目标函数，内层以治理后电压畸变率最低为目标函数，并用改进多目标秃鹫算法进行求解，得到有源电力滤波器（active power filter,APF）的最佳安装数量、位置和容量。最后，以IEEE 33节点为例，对所提算法进行仿真研究，以检验所提算法在电网谐波治理中的应用效果。
Abstract：With the large-scale integration of distribution networks,harmonic pollution presents characteristics of high density,decentralization,and networked behavior.Traditional point-to-point harmonic control methods cannot meet the requirements.To address this,this paper proposes a dual-layer optimization configuration method for active filters,based on harmonic emission weighting and sensitivity analysis,which balances both the cost and effectiveness of multi-harmonic mitigation in distribution networks.Firstly,a harmonic emission weight model is established,and through sensitivity analysis of harmonic mitigation,a harmonic prevention zone is constructed based on the voltage detection active power filter (VDAPF) access point as reference;Secondly,the dual-level optimization model is employed to solve the problem.The outer layer of the optimization model has the objective function of minimizing the operating cost of the VDAPF,while the inner layer has the objective function of minimizing the voltage distortion rate after mitigation.The improved multi-objective vulture algorithm is used to solve the problem and obtain the optimal installation quantity,location,and capacity of active power filter(APF).Finally,taking the IEEE33-bus system as an example,simulation studies are conducted to verify the application performance of the proposed algorithm in harmonic mitigation within the power grid.
