A comprehensive evaluation method of solitary network frequency control strategy based on multiple indicators is proposed to improve the accuracy of solitary network frequency control. Firstly, the evaluation index system of the orphaned network frequency control strategy is established, and on this basis, the single control strategy is evaluated. The objective and subjective weights of the indicators are determined by the entropy value method respectively, and the comprehensive evaluation value of the control strategy is obtained, and the orphaned network frequency control model is preferred. The experimental research is conducted through the actual data of an isolated network in a certain place, and the experimental results show that the method can effectively judge the control effect of each isolated network frequency control strategy, and the most suitable isolated network frequency control strategy can be selected in a targeted manner.
