Time-of-use electricity price period division optimization method and system, terminal equipment and medium

The invention discloses a time-of-use electricity price period division optimization method and system, terminal equipment and a medium, and the method comprises the steps: obtaining the daily load data of a user, and determining the peak membership and valley membership of each time point through a fuzzy semi-gradient membership function; according to a fuzzy clustering algorithm, the peak membership degree and the valley membership degree, determining an initial time period division scheme; and correcting the initial time period division scheme by using a user responsivity attribute index to obtain a target time period division scheme. According to the time-of-use electricity price period division optimization method provided by the invention, the initial period division scheme is optimized and adjusted by constructing the user responsivity attribute index, and a basis is provided for subsequent pricing model optimization. The method not only can enhance the peak clipping and valley filling energy efficienc
