Power grid risk prediction method and device, storage medium and computer equipment

The invention provides a power grid risk prediction method and device, a storage medium and computer equipment, and the method comprises the steps: obtaining a preset risk index set when a risk prediction instruction is received, so as to determine risk index data corresponding to the risk index set; constructing a risk pre-judgment model according to the risk index data; wherein the risk pre-judgment model takes the lowest power grid safety index as a target, and takes the wind field power, the photovoltaic station power, the fluctuation load power and the operation state of each power transmission line in the N-1 fault scene as a decision variable set to be optimized; and obtaining a preset constraint condition, and solving the risk pre-judgment model to obtain at least one potential risk scene. Uncertain factors such as related data and load fluctuation of new energy are taken as decision variables instead of probability modeling, so that the data magnitude required by modeling can be reduced, the difficul
