Grid-connected Stability Analysis of Grid-forming Fuel Cell Power Generation Systems Based on Dynamic Characteristics
摘要
Abstract
Against the backdrop of the accelerated energy transition,the application of grid-forming capabilities of fuel cells holds great potential.This paper proposes a small-signal stability analysis method based on dynamic theory for the multi-timescale stability problem of grid-forming fuel cell power generation systems.Firstly,a small-signal model of the grid-forming fuel cell power generation system is established.Secondly,by introducing the quantitative indicators of the synchronous component and the damping component,the dynamic model of the system is constructed,revealing the stability evolution law under various operating conditions.Then,by combining the participation factor analysis method with the dynamic characteristics,the internal dynamics of the fuel cell and the dynamic coupling mechanism between the cell-side DC voltage control parameters and the power synchronous control and AC voltage control of the grid-forming converter are deeply analyzed.Finally,the time-domain simulation based on the MATLAB/Simulink platform and the hardware-in-the-loop experiment verification show that the proposed analysis method can accurately predict the stability boundary of the system.关键词
