Integrated energy power distribution system based on cellular topology and operation method thereof

Abstract

The invention relates to an integrated energy power distribution system based on cellular topology and an operation method thereof, the integrated energy power distribution system comprises core equipment and integrated energy base stations, and the interconnection mode between the integrated energy base stations and between the integrated energy base stations and a superior power grid is defined. Under the cellular topology, comprehensive energy power distribution system operation methods taking economy as a target and taking balance as a target are respectively designed, and operation constraint conditions are constructed by considering operation characteristics of the system. Under the double-carbon background, compared with a single-category energy system, a comprehensive energy system in which various energy sources such as electricity, gas or heat are coordinated and complemented is constructed, and the method has important significance on energy conservation and emission reduction of the whole system. The main way for realizing multi-energy complementation is at the user consumption side, so that for a power system, a power distribution system is likely to be evolved into a comprehensive energy power distribution system firstly. The system constructed by the invention can provide a basis for a future urban multi-energy interconnection and high-proportion renewable energy access power distribution network structure design and operation method.

Description

technical field [0001] The invention belongs to the technical field of power distribution planning and operation, in particular to a comprehensive energy distribution system based on cellular topology and an operation method thereof. Background technique [0002] The network structure is the basic element that affects the safety and efficiency of the network system operation, and determines the upper limit of the system improvement effect of equipment, operation and management technologies. For example, in a single-radiation line structure, feeder automation technology can only achieve rapid isolation of faulty areas, while in a hand-in-hand connection line structure, the use of feeder automation technology can further improve the transfer capability of the network. Therefore, a reasonable grid structure is a key factor to meet the needs of the future distribution network, which can enhance the coordinated support capability of dispatchable resources in operation under the a...
