摘要：
Aiming at the challenge of static voltage stability region（SVSR） construction of AC／DC system with hybrid multi-terminal high voltage direct current （Hybrid-MTDC），a predictor-corrector method to investigate the SVSR boundary（SVSRB） of AC／DC system with Hybrid-MTDC is presented. Considering the control strategy switching characteristics of the multi-type converter stations and the control strategy cooperation among converter stations，a continuation power flow（CPF） model for the AC／DC system with Hybrid-MTDC is constructed to find the first critical point on the SVSRB. By using the obtained first critical point information，according to the topological characteristics of SVSRB，the proposed predictor-corrector model is used to obtain the adjacent critical point in SVSRB of AC／DC system with Hybrid-MTDC rapidly and correctly，and then the SVSR of AC／DC system with Hybrid-MTDC is formed. The proposed method is analyzed and verified in IEEE 5-bus and IEEE 118-bus test systems with Hybrid-MTDC. The result shows that the proposed method can achieve the SVSR construction in AC／DC system with Hybrid-MTDC effectively and correctly. © 2023 Electric Power Automation Equipment Press.
