摘要
微电网不仅合理有效解决了大电网与分布式电源之间的融合问题,而且充分发掘了分布式电源的各项优势。微电网中的分布式电源基本上都需要通过电力电子设备与大电网进行接口,而这些电力电子设备又会对电网带来谐波问题。因此,如何对微电网的谐波进行合理控制具有重要研究意义。首先指出滤波系统应用于微电网环境下所面临的问题与挑战,进而对一种非常适用于微电网谐波治理的混合滤波器控制策略及其参数设计原则进行了研究,最后通过实验结果验证了所提出的控制策略及系统参数选择的合理性。
Micro-grid not only solves the fusion problem of traditional power grid and distributed generation effectively,but also gives full play to distributed generation benefits. The distributed generation in micro-grid is connected to the power grid by using power electronic devices,which generate serious harmonic problem. Therefore,it is very important to research on harmonic elimination of micro-grid. The problem and challenge faced by filter system with micro-grid were pointed out and then the control strategy and parameter design for a new hybrid power filter especially suitable for micro-grid were analyzed. Finally,experimental results verify the effectiveness of the proposed control strategy and parameter design.
