description The invention discloses a method for carrying out rapid load adjustment by utilizing superheated steam stored energy in front of a machine, and the method comprises the steps: respectively obtaining the superheated steam stored energy at a real-time load point and a target load point through a new calculation mode, and calculating a steam stored energy deviation; and then, the energy storage deviation is equivalently converted into load deviation and pressure deviation, and the deviation is introduced into feedforward of a coordination control system, so that the purpose of quickly adjusting the load by utilizing superheated steam energy storage is achieved. According to the method, the experiment of a field unit is avoided, the energy storage coefficient of a typical load point is calculated equivalently through historical data, steam turbine feedforward control is designed on this basis, and the rapidity of unit load adjustment is improved on the basis of fully utilizing energy storage of a superheated stea
