According to the method, while accurate solving of the power distribution network operation optimization mathematical model is guaranteed, the complexity of binary variable solving is reduced, and the solving speed of the power distribution network operation optimization mathematical model is improved, so that the daily growth calculation amount of the power system dispatching optimization model at the present stage is met.

Description

technical field [0001] The invention relates to the field of power system planning and operation and the theory of quantum mechanics, in particular to a demand-side response collaborative optimization method based on a quantum approximate state. Background technique [0002] Under the background of the energy revolution driven by the national strategic carbon reduction goal of "carbon peaking and carbon neutrality", a high proportion of new energy sources and gradually replacing fossil energy will become the mainstream development trend. Determinism brings a series of problems to the reliable operation of the grid. In order to ensure the stable operation of the power system, if the traditional method is used to adjust the output of the thermal power unit to stabilize the fluctuation of the new energy output, on the one hand, the frequent start and stop of the thermal power unit will increase the operating cost of the thermal power plant and aggravate the fatigue and fatigue ...
