When the complete blackout of power system happened, selecting out the optimal black-start scheme quicklySandSaccurately is a primary for making sure fast restoration. A method based on game theory and radar chart was proposed to assess black-start schemes. Firstly, indexes’ objective and subjective weight were calculated by using entropy method and IAHP. And then game set model and subjective and objective weight were combined to establish integrated weight; Secondly, for ranking and optimization black-start schemes, radar chart was drew based on central angle related to integrated weight, and feature vector was extracted to construct reasonable evaluation function. This method was applied in TianJin’s power grid to prove its effectiveness. Compared with existing numericalSmethods, not only its calculation process is more efficiently, but also two types of results with calculated value and radar chart are provided. Decision basis could be offered scientifically and efficiently for dispatchers to select black-start schemes.
