The invention discloses a user side comprehensive energy system regulation and control method, which is characterized by comprising the following steps of dividing a regulation and control period intothe regulation and control time periods according to the user side load energy demands and a time sequence rule; calculating by adopting a fuzzy clustering algorithm based on the regulation and control time periods to obtain the energy consumption grades; and based on the regulation and control time periods and the energy consumption grades, combining with the energy value label sorting of the energy devices to perform regulation and control, so that different grading standards are set under different regulation and control scenes and different regulation and control time periods, the gradingregulation and control of the user-side comprehensive energy system are more reasonable and flexible, and the problem that the supply and demand balance of the energy generation and distribution cannot be achieved, is solved.
