| description | The invention discloses a method and system for evaluating new energy voltage support strength in real time, and belongs to the technical field of large power grid stability analysis and control application. The method comprises the following steps: calculating a short-circuit ratio of a new energy multi-station on the basis of an alternating-current power grid equivalent impedance matrix; establishing a new energy multi-station critical short-circuit ratio data set; obtaining a prediction model; and obtaining target measurement data of the new energy multi-station in real time, inputting the target measurement data into the prediction model for calculation to obtain a real-time critical short-circuit ratio of the new energy multi-station, obtaining a real-time short-circuit ratio of the target measurement data, and calculating the real-time critical short-circuit ratio of the new energy multi-station according to a difference value between the real-time short-circuit ratio and the real-time critical short-ci |
