摘要
联网运行和孤岛运行是微电网主要运行模式,前者有着较为良好的频率稳定性,而后者则会发生频率扰动现象,如何有效解决这种问题,是当前微电网推广应用过程中的研究重点和热点,已经引起了国内外学者及专家的广泛关注。此文简要介绍了微电网,分析了较为常用的传统下垂控制策略,在此基础上提出了一种微电网电源虚拟惯性频率控制策略,并通过仿真分析对其可操作性进行了验证,旨在充分发挥微电网的应用优势。
Networking operation and islanding operation are main operating modes of microgrid. The former has relatively good frequency stability, while the latter is subject to frequency disturbance.How to effectively solve this problem is the focus and hotspot of current microgrid application process attracting widespread attention from domestic and foreign scholars and experts.The paper briefly introduces the microgrid and analyzes the commonly used traditional droop control strategy.Based on this,it proposes a virtual inertial frequency control strategy of microgrid power supply,and validates its operability through simulation analysis to take application advantages of microgrid.
