To further enhance the closed-loop operation level of real-time generation scheduling and achieve coordinated and stable operation of regional and provincial power grid

a generalized tie-line mode real-time generation scheduling model is proposed. The concept of generalized tie-line scheduling is introduced for the first time and a mathematical model each is developed for the regional and provincial power grid

respectively. Coordinated allocation of real-time deviation is realized between the two types of mathematical models by tracking their respective generalized tie-line scheduling while guaranteeing the execution rate of the geographical tie-line. In addition

the regional power grid realizes overflow among the control areas and analyzes the tracking situation of each control area generalized tie-line scheduling by means of two-stage optimization.
