| 摘要: |
| 为了提高单相分布式电源的能量利用效率，提出了两种基于自适应陷波器的单相分布式电源并网的控制方法，它们应用于不同的场合。其中 P控制系统以有功功率的控制为核心，PQ控制系统以有功功率和无功功率的控制为核心。采用提出的方法，可以使得光伏电源以最大功率并网，电池电源输出所需功率。在某些特殊场合，采用提出的PQ控制可以使分布式电源进行一定的无功功率补偿。由于自适应陷波器在信号检测方面具有优良的性能，与传统的并网控制系统相比，两种控制方法结构简单，抗干扰能力强。最后通过仿真验证所提方法的快速性和准确性。 |

| Abstract: |
| In order to improve energy utilization efficiency of signal-phase distributed generation (DG), two novel single-phase DG grid-connected control methods are proposed based on adaptive notch filter (ANF) and they are applied in different conditions. The P control system takes active power control as the core, and the PQ control system takes active power and reactive power control as the core. The photovoltaic source can output the maximum power when it is connected with the grid, and the battery source outputs required power by using the proposed methods. In some cases, the DGs can provide reactive power compensation to some extent if the proposed method is employed. Since the ANF has a good performance on signal detection, compared with the traditional grid control system, the two methods have simple structures and offer a high degree of immunity and insensitivity to the grid disturbance. Finally, the rapidity and accuracy of the proposed methods are verified by simulation. |
