Small-Signal Stability Analysis and Parameter Optimization of Grid-Forming Wind Turbine

The grid-forming virtual synchronous permanent magnet synchronous generator (PMSG) wind turbine considering source-side characteristics, as a novel research focus, lacks comprehensive studies on its stability and parameter optimization. This paper establishes a state-space model incorporating source-side characteristics and the dynamics of both machine-side and grid-side converters. Using eigenvalue analysis, the impact of control parameters on stability is studied, and an optimization model for control parameters is proposed. The particle swarm optimization (PSO) algorithm is employed for global parameter optimization. A 5 MW PMSG simulation model in PSCAD/EMTDC validates the theoretical analysis and parameter design.
