Island micro-grid dispatching operation feasible-solution-free short-time line dynamic capacity increasing method

The invention relates to a non-feasible solution short-time line dynamic capacity increasing method for dispatching operation of an island micro-grid. The method comprises the following steps: generating a daily load curve sample of the island micro-grid; constructing an island micro-grid economic dispatching model to solve the dynamic increasing capacity of the line current-carrying capacity; and introducing the steps of equality constraint completion and inequality constraint correction, and predicting a line needing dynamic capacity increasing and the dynamic capacity increasing capacity thereof by using a neural network. According to the invention, through dynamic capacity increase of a transmission line, the problem of boundary adjustment when no feasible solution exists in island micro-grid dispatching operation is solved; a rich load scene is provided for deep learning model training; and finally, introducing the steps of equality constraint completion and inequality constraint correction, solving a qu
