摘要

微电网是现代电力系统的重要组成部分。低惯性贡献的分布式发电、低压馈线、不平衡负荷、比X/R比和低短路功率值的存在，使得对分布式发电稳定性方面的观察不同于传统大系统稳定性。本文综述了适用于永磁发电机的电压和频率稳定控制方法。简要介绍了永磁同步电动机的分类和工作方式。提出了几种电压和频率控制方法，并提出了分层频率控制方法。

Microgrid Stability: A Review on Voltage and Frequency Stability

Microgrids (MG) take a significant part of the modern power system. The presence of distributed generation (DG) with low inertia contribution, low voltage feeders, unbalanced loads, specific X/R ratio and the low short-circuit power values makes the observation of the MG stability aspects different from the conventional bulk power system stability. This paper presents a review on the voltage and the frequency stability control methods applicable on the MGs. A brief overview of classification of MGs and MG operating modes is given. Some methods of voltage and frequency control are proposed and hierarchical frequency control is presented.
