In order to improve security operation level of UHV AC-DC power grid, the synchronous condenser is widely used in UHVDC sending and receiving power grid. A comprehensive evaluation method of synchronous condenser configuration scheme for weak sending-end HVDC power grid is introduced. Firstly, a comprehensive evaluation index system comprising the transient overvoltage, the steady-state overvoltage, the voltage stability, the effective short circuit ratio, and the investment cost is constructed. Secondly, intuitionistic fuzzy analytic hierarchy process (IFAHP) is used to determine the weights of evaluation indexes. IFAHP has shown advantages in handling uncertainty of evaluation index comparison for decision maker. Finally, the TOPSIS method is employed to rank the schemes. The simulation results of actual power grid demonstrate the effectiveness and superiority of the proposed method.
