Small-Signal Modeling and Dynamic Analysis of Microgrid
This paper researches the small-signal stability of a 3-node microgrid,which consists of PV power generation,wind power generation,energy storage battery,resistance-inductance load and induction motor.Establish a complete small-signal model for the microgrid; analyze the small-signal stability of a calculation case by means of eigenvalues analysis ; analyze the relevance between between oscillation mode and state variable by means of participation factors; adjust the controller's parameters by eigenvalue locus method to improve the system small-signal stability.Finally,the simulation model of PV power generation system was constructed based on PSCAD/EMTDC.Simulations were conducted on the sharply rising light intensity and plunged wind speed,verifying the correctness of the small disturbance modeling and analysis.
