Typical operation mode generation method and device of power system

The invention relates to the technical field of power system operation, and particularly provides a typical operation mode generation method and device of a power system, and the method comprises the steps: configuring the initial output of each power supply in a regional power grid in a preset typical operation scene; carrying out load flow calculation on the regional power grid to obtain load flow convergence conditions, balancing machine out-of-limit conditions and line out-of-limit conditions of the regional power grid; adjusting the start and stop states of the fire/hydroelectric generating units except the specific fire/hydroelectric generating units in the regional power grid under the preset typical operation scene based on the load flow convergence condition and the balancing machine out-of-limit condition of the regional power grid; and correcting the initial output of each fire/hydroelectric generating set in the regional power grid in the preset typical operation scene based on the line out-of-lim
