基于DIgSILENT软件的微电网平滑切换的研究
|
摘要
实现微电网并网/孤岛运行模式平滑切换是保证微电网安全可靠运行的前提。介绍了微电网分布式电源逆变器的P/Q和Vlf两种控制方式,并在DIgSILENT仿真软件中对由P/Q控制型分布式电源和V/f控制型分布式电源组成的微电网进行了并网转孤岛模式的仿真研究,实现了微电网平滑切换运行,维持了系统的电压和频率的稳定。
Smooth switching between grid-connected mode and grid-isolated mode in microgrid is a precondition for ensuring the sate and reliable operation of the microgrid. This paper introduces the P/Q and V/f control method used in the distributed generation inverter for the microgrid, and makes a simulation research on the microgrid composed of P/Q control and V/f control based distributed generation in changing the operation mode from grid-connected to grid-isolated based on DIgSILENT simulation software, realizing the smooth switching of the modes and ensuring the voltage and frequency stability of the system.
