Blockage identification method and system considering new energy uncertainty and energy storage

The invention relates to a blocking identification method and system considering new energy uncertainty and energy storage, and is used for solving the problem that blocking identification is difficult due to the fact that the new energy output level of a novel power system of new energy and an energy storage device cannot be accurately evaluated. According to the scheme, the load loss power of each load node at each time is obtained by using the robust blocking evaluation model, and then the blocking degree of the power transmission line between the load nodes is analyzed and identified based on the load loss power of each load node at each time. The objective function of the robust blocking evaluation model is to minimize the load loss amount of the power system. Constraint conditions met by the method include new energy output constraint based on new energy uncertainty, energy storage device constraint based on new energy uncertainty, thermal power generator constraint based on new energy uncertainty, and
