Load shedding method for double-series coal chemical production process enterprise power grid

The invention provides a load shedding method for a double-series coal chemical industry production process enterprise power grid. The load shedding method comprises the steps that 1, different process loads are graded at intervals according to whether double-series operation exists or not and the influence degree on a production process; step 2, grading loads in each grade of load intervals according to the interlocking complexity of the production process, and arranging all the load intervals according to a priority sequence; step 3, calculating the cuttable load capacity of each grade according to the grading result; according to the power of the large power grid connection section before tripping, the load shedding amount is calculated; and 4, in combination with the power vacancy which can be borne by the enterprise power grid, according to the comparison of the load capacity needing to be sheared and the shearable load capacity of each gear, selecting the shearable load in an accumulation mode according
