摘要

针对微电网孤岛运行时分布式电源（DG）所采用的传统电压/频率下垂控制方法的不足，提出了一种具有比例-积分-微分（PID）结构的改进下垂控制方法，并根据电压和频率的变化，使用模糊推理技术来优化相应参数;设计了一种自适应模糊PID下垂控制器，以进一步有效减小微电网孤岛运行时由于扰动所造成的电压/频率振荡。通过仿真计算验证了所提出的模糊PID下垂控制器设计的正确性和有效性。

Abstract

To overcome the inherent shortcomings of the commonly used voltage/frequency droop control for distributed generators（DGs）in islanded microgrids，an improved droop control with a proportional-integral-derivative（PID）structure is proposed.The PID parameters are optimized using the fuzzy logical reasoning technology based on the variations of voltage and frequency.And then an adaptive fuzzy PID droop controller is designed to further reduce the oscillations of voltage and frequency due to disturbances from microgrids.The correctness and validity of the proposed fuzzy PID droop controller are verified by simulation.
