中文摘要:
      现存的LCL滤波器设计方法未能有效兼顾逆变器电流控制对滤波器设计的限制以及电网阻抗对并网稳定性的约束。该文通过建立含数字延迟的弱电网下LCL滤波并网逆变器模型,得到控制性能及并网稳定性对参数设计的约束条件,建立损耗最小,成本最低,对电网阻抗适应能力最好,电流跟踪性能最佳的多目标优化模型,并采用目标函数离差排序法确定权重系数,自适应权重PSO求解。该设计方案在保证滤波性能和制造成本的同时,增强了LCL并网逆变器在弱电网下的稳定裕度。最后,通过仿真分析验证了该设计方案的正确性与有效性。
英文摘要:
      The existing LCL-filter design method fails to effectively balance the limitations of the inverter current control on the filter design and the grid impedance to the grid stability. In this paper, the control performance and grid-connected stability constraints on parameter design are obtained by establishing a LCL-filtered grid-connected inverter model with weak grid as well as digital control delay. Then set up the multi-objective optimization model with the minimum loss, the lowest cost ,the best impedance adaptability to the grid and the best current tracking performance . The objective function sort deviation is used to determine the weight coefficient and the adaptive weight PSO algorithm is used to solve the optimization problem, This scheme enhances the stability margin of the LCL-filtered grid-connected inverter under weak grid while ensuring the filtering performance and manufacturing cost. Finally, the rationality and feasibility of the design scheme are verified by simulation analysis.
