The invention provides a regional multi-system double-layer decentralized optimal scheduling method considering a double-layer carbon emission optimal distribution model, and constructs a regional multi-energy system double-layer carbon emission optimal distribution model, an upper regional multi-energy main system mainly considers a power distribution network system, a gas distribution network system and a heat distribution network system; the real-time carbon emission constraint is formulated based on real-time environment monitoring, the historical carbon emission of each multi-energy subsystem in the lower-layer area is decomposed to each multi-energy subsystem in the lower-layer area in real time, and each multi-energy subsystem in the lower-layer area needs to meet the real-time carbon emission constraint while being optimized; and finally, solving the double-layer decentralized optimization scheduling model of the regional multi-energy system between the upper layer and the lower layer by adopting an improved target cascade analysis method. According to the method, the total network loss of the upper-layer distribution network system of the regional multi-energy system can be reduced, the operation cost of each energy subsystem in the lower-layer region can be reduced, and meanwhile, the optimal distribution scheme of the overall carbon emission of the regional multi-energy system is determined.
Description
technical field [0001] The invention belongs to the technical field of power system operation management, and in particular relates to a regional multi-system double-layer decentralized optimal dispatching method considering a double-layer carbon emission optimal distribution model. Background technique [0002] At present, China is still in the middle and late stages of rapid urbanization, and energy consumption and carbon emissions in various regions of the country continue to increase every year. However, with the continuous expansion of energy demand and the continuous deterioration of ecological environment problems, the regional multi-energy system has shown a new development trend. The traditional multi-energy system planning and operation is limited to a single form of energy such as electricity, natural gas, cold, and heat, and cannot fully utilize the complementary advantages and synergistic benefits of multi-energy systems between regions. [0003] Compared with ...
