摘要:
 针对传统构网型逆变器功率控制存在动态性能差及控制自由度低的问题,提出了一种构网型逆变器灵活并网功率控制方法。首先,设计了比例积分下垂的构网型功率控制,用于缓解下垂系数与阻尼系数之间的调节矛盾。同时采用前馈控制方法,从而引入可配置的零点,通过零点配置将二阶系统降为一阶系统,从而使得功率参考值跟踪及电网频率动态响应均具有较好的动态性能,同时调节时间可定制化灵活设计且功率动态无超调。仿真结果表明,所提功率控制策略在动态过程中能实现对功率参考值的无超调跟踪,且动态调节时间与理论设计结果相一致,并可自主响应电网频率及电压变化,具有良好的鲁棒性。最后搭建了构网型逆变器实验平台,进一步证实了该方法的正确性与有效性。
Abstract:
 To address the problems of limited dynamic performance and low control flexibility in the traditional power control of grid forming inverters,a flexible grid connected power control method for grid forming inverters is proposed.First,a proportional–integral (PI) droop based grid forming power control strategy is designed to alleviate the tuning conflict between the droop and damping coefficients.A feedforward control method is then introduced to incorporate configurable zeros.By assigning these zeros,the second order system is reduced to a first order one,thereby achieving improved dynamic performance in both power reference tracking and grid frequency response.The proposed method allows customizable adjustment of settling time and ensures power dynamics without overshoot.Simulation results demonstrate that the proposed power control strategy achieves overshoot free tracking of the power reference during transients,with dynamic settling times consistent with theoretical designs.Moreover,the inverter autonomously responds to grid frequency and voltage variations,exhibiting strong robustness.Finally,an experimental platform for the grid forming inverter was established,further verifying the correctness and effectiveness of the proposed method.
