This application relates to the field of data processing technology, and discloses an orthogonal fusion model of emotion, fatigue, and subjective will, as well as a method for assessing mental state. For the problem of emotion recognition, this application proposes a spatiotemporal entropy feature extraction method, which has good adaptability to small sample EEG data; for the problem of low recognition rate in fatigue state recognition, it proposes a power spectrum normalization feature extraction method for brain functional connectivity, which shows higher accuracy in fatigue state recognition; for the problem of feature fusion of emotion, fatigue, and work will, it proposes a mental state assessment model based on the Taguchi orthogonal method that fuses subjective and objective indicators. Experimental results show that the spatiotemporal entropy feature emotion recognition, the power spectrum recognition fatigue state recognition of brain functional connectivity, and the orthogonal fusion mental state assessment model of subjective and objective indicators proposed in this invention can complete the task of recognizing emotional state, fatigue state, and mental state.

This invention relates to an improved method for optimal scheduling of an integrated power-electricity interconnected energy system, belonging to the field of electrical technology. The method includes the following steps: S1) analyzing the structure of the integrated power-electricity interconnected energy system; S2) building a mathematical model for optimal scheduling of the integrated power-electricity interconnected energy system; S3) solving and comparing the optimal scheduling methods of the integrated power-electricity interconnected energy system; and S4) performing simulation analysis of the optimal scheduling of the integrated power-electricity interconnected energy system. Based on decoupling analysis, this invention addresses the problems of existing distributed power flow calculation methods for integrated power-electricity interconnected energy systems by proposing an improvement based on the Schmitt orthogonal method. The improved method and the original optimal scheduling method are simulated separately, and the results are analyzed. The improved method reduces the condition number to 1 through preprocessing, reducing the number of iterations and shortening the calculation time, thereby improving computational efficiency.
