Abstract
This paper presents a novel CPF-GMRES algorithm based on an adaptive preconditioner to overcome the computational bottleneck in the analysis of large-scale power system voltage stability with CPF. Considering the combination details of CPF and GMRES, an adaptive preconditioning structure is proposed to reduce the formation times of preconditioner. Initialize the preconditioning matrix in the predictor of CPF, and modify it with Broyden method in the corrector. Large number add-in strategy and a replenished one are applied to deal with the influence of PVPQ bus-type switching. Numerical results with IEEE 118-bus test system and a real power grid verify the effectiveness of the proposed algorithm, and indicate that a remarkable speed advantage is obtained compared with the conventional CPF-GMRES with the preconditioner of ILU factorization.
