The invention provides a power system economic dispatching system and method, and the system comprises a generator set output power acquisition device, a wind power output power acquisition device, a power grid constraint condition acquisition device, and a controller which is connected with the generator set output power acquisition device, the wind power output power acquisition device and the power grid constraint condition acquisition device. The controller is configured to set generator set output power and wind power output power in a power system, establish an initial economic dispatching model based on a preset wind power output power prediction interval and operation constraint conditions, and then perform optimization processing on the initial economic dispatching model by using a teaching and learning algorithm. Therefore, the globally optimal scheme is obtained, and the operation of the power system is more economical and reliable. 本申请提供的一种电力系统经济调度系统及方法，所述系统包括发电机组输出功率获取装置、风电输出功率获取装置和电网约束条件获取装置，以及连
