摘要：
The reactive power and voltage sensitivity of AC/DC power system is an important index to measure the interaction between AC subsystem and DC subsystem, and guide reactive power optimization and control. The gradual application of new generation large capacity SC(Synchronous Condenser) in sending and receiving ends of UHVDC(Ultra High Voltage Direct Current) power system has brought challenges to the existing calculation method of reactive power and voltage sensitivity. Therefore, a sensitivity calculation method for different types of nodes is proposed based on the linearized power flow equation of AC/DC power system, and the physical meaning of the sensitivity concerning PV node is analyzed. The EPRI 36-bus system is taken as an example, and the simulative results verifies the correctness of the proposed method. © 2018, Electric Power Automation Equipment Press. All right reserved.
