Invited Talk Title | Transient Stability Analysis and Stabilization Strategy for Grid-Forming Converters under Multiple Constraints
Abstract
With the rapid development of new-type power systems dominated by renewable energy and power electronic devices, low inertia, weak grid support and prominent stability problems have become critical challenges. Grid-forming (GFM) converters, as key equipment for new power system construction, face severe transient synchronization instability under large disturbances due to limited overcurrent capability and complex voltage-dynamic coupling. This report focuses on the transient stability analysis and stabilization strategies of GFM converters under multiple constraints. First, the windup phenomenon of GFM converters with priority current limiter is revisited, and a power angle criterion for this phenomenon is derived based on critical switching angle and fault-clearing angle. Second, the voltage-dynamic coupling effect on transient stability in high R/X ratio networks is revealed, and a port-controlled Hamiltonian (PCH) model is established to characterize the stability boundary accurately, with an energy reshaping control proposed for stability enhancement. Furthermore, a coordinated control strategy is designed to balance transient stability, GFM capability and current limitation by adaptively adjusting terminal voltage characteristics. Experimental results verify the effectiveness of the proposed methods in enhancing transient performance under various grid strengths. This work provides theoretical support and technical solutions for the reliable and stable application of GFM converters in new-type power systems.
