Layered optimization scheduling method for deep peak regulation of thermal power generating unit

The invention relates to the technical field of power grid peak regulation, and discloses a hierarchical optimization scheduling method for deep peak regulation of thermal power generating units, which comprises the following steps: dividing a power system into a plurality of subsystems, each subsystem comprising a plurality of thermal power generating units, and meanwhile, the load requirements of the subsystems are different; through a multi-objective optimization algorithm, sustainable utilization of the environment and resources is considered while system requirements are met; independently calculating each subsystem by adopting a hierarchical optimization algorithm to obtain an optimal scheduling scheme; the scheduling of the thermal power generating unit is intelligently optimized by using an artificial intelligence algorithm; in consideration of uncertainty and volatility of new energy, the new energy resources are dispatched in a range and are dispatched together with a thermal power generating unit;
