Abstract

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.

Description

technical field [0001] The present invention relates to comprehensive energy, in particular to a user-side comprehensive energy system hierarchical control method and system. Background technique [0002] The integrated energy system on the user side is an integrated energy network in which multiple energy sources interact and complement each other. During the operation of the user-side integrated energy system, it is impossible to achieve the balance of supply and demand, the consumption and suppression of renewable energy for the generation, transmission and distribution, conversion, storage, consumption, and transaction of various energy sources. The integrated energy system on the user side can not only control all units at one level, but also divide them into several energy stations according to the spatial distribution of energy load and energy supply equipment for hierarchical management and control. Contents of the invention [0003] In order to solve the above-me...
