Stability Analysis with MFD Criterion in Meshed Microgrid Based on Impedance Model
摘要
Abstract
This paper addresses the high-frequency harmonic stability of meshed inverters in islanded microgrid.Firstly,the impedance based closed-loop transfer function matrix of the microgrid which contains many meshed inverters is obtained.Then the stability of the system is assessed by the Matrix-Fraction Description (MFD) stability criterion.The analysis of the system has smaller amount of computations and simple character because of the impedance-based analytical approach.Furthermore,simulations and experimental results are performed to validate the effects of the line parameter and control parameter of the voltage and current controllers on stability.In addition,the case verify the correctness of the system modeling and the effectiveness of the MFD stability criterion.关键词
