A cogeneration unit and wind power joint heating system and a scheduling method therefor. The joint heating system comprises a coal-fired steam-extraction condensing-steam cogeneration unit (A), a wind turbine generator unit (B), an air conditioner heat pump () parallel-connected to the coal-fired steam-extraction condensing-steam cogeneration unit (A) and to the wind turbine generator unit (B) via a power cable network (), and a hot water heating radiator () connected to the coal-fired steam-extraction condensing-steam cogeneration unit (A) via a heating pipe network (). The joint heating system also comprises an integrated scheduling control device (), a first remote centralized controller (), a second remote centralized controller (), and a third remote centralized controller (). Heating is provided to a user by the hot water heating radiator () and the air conditioner heat pump (); while electricity is provided jointly by the coal-fired steam-extraction condensing-steam cogeneration unit (A) and the wind turbine generator unit (B). The scheduling method comprises: after detecting over a period of time the state of power supply and the state of power consumption of the user via the integrated scheduling control device (), making a prediction for an upcoming period of time, and then scheduling on this basis. Under the premise of ensuring electricity supply and heat supply, the scheduling method reduces hot water flow outputted for heating, and compensates with electricity heating.
